m o c . k c o t s r e t t u h S / o n N E o c N © i i l | practice management The COVID-19 practice manager 2021: Four steps to confi dence—Part 2 Chris Barrow, UK Business author Michael Gerber expanded on this in his award-winning 1995 book, The E-Myth Revisited. By sharing with his readers a parable—the story of Sarah’s pie shop—Gerber was able to demonstrate that every business employs five basic management systems (with my dentistry examples): – marketing systems—the way you get new patients in the door; – patient journey systems—the way you care for and sell treatment to your patients; – financial systems—the way you measure and analyse the money that flows through your business; – operational systems—the way you make sure that things work and are compliant; and – team systems—the way you hire, train, appraise, pay, promote, discipline and remove your people. The role of the practice manager as head of systems is to ensure that all of these systems are in place and are fol- lowed to the letter—because if you do that, success follows. Introduction I promised you a series of articles specifically for practice managers as we move into the post-pandemic environ- ment, to cover: – leadership; – management; – teamwork; and – extreme self-care. In the first part of this series, we looked at the character- istics of great leadership and how this applies to the role of the practice manager. We discussed the communities who look to you for guidance; answers to some common FAQs from practice managers; your personal manifesto; the Karpman Drama Triangle; the Courtesy System; and The Chimp Paradox—overall, what it takes to be a leader, even when you do not feel like one (most of the time—as great leaders will tell you). Would it not be great if I could say so off you go then and finish this article now? Sadly, it is rarely that simple. What gets in the way? If a system is the wrong system, you will soon find out. That is why it is essential to have your sys- tems constantly under review. Think about how many systems became defunct after lockdown 1.0 and had to be adapted to our new working environment. The ability to change course quickly when external factors change is called “pivoting”, and it is a sign of an agile business when it can pivot quickly. Many of us have learned all about pivoting and agility in the last 15 months. Those who have not are in trouble. As a man- ager, you have to equally be aware of internal changes in your business, whether systemic or the people you hire, and exercise the same degree of agility in changing course (or crew) should it be necessary. Management The economic pundits suggest that franchises are the most successful business model in history, measured by financial return on investment. Franchises make more money because they are designed to create simple and repeatable systems which, if followed, will ensure success. For many years now I have shared a monthly manage- ment meeting agenda with my clients as a template for the questions they should be able to answer on a regu- lar basis. Imagine this as a sea vessel taking a positional reading in order to determine whether it is on course. As you work through this agenda, ask yourself whether you have this information to hand and/or how quickly 06 2 2021

| opinion “You cannot push people into digital dentistry” An interview with Prof. Markus Blatz, chair of the Department of Preventive and Restorative Sciences By Iveta Ramonaite, Dental Tribune International Prof. Markus Blatz has always been excited about technological advancements in dentistry. However, he only uses dental technology when it is evidence-based and provides a true benefi t for the patient. It is safe to say that Prof. Markus Blatz has dedicated his life to the furthering of clinical and theoretical knowl- edge in order to advance dentistry. His passion for the dental profession is unmistakable and can be seen in his numerous degrees, professional awards and academic publications, among other achievements. In his current role, Blatz serves as chair of the De- partment of Preventive and Restorative Sciences and assistant dean for digital innovation and professional development at the University of Pennsylvania School of Dental Medicine in Philadelphia, US, where he founded the Penn Dental Medicine CAD/CAM Ceramic Cen- ter and is leading the Digital Innovation Initiative. In this interview, he discusses all things digital dentistry, in- cluding the CAD/CAM workflow, 3D printing and the use of artificial intelligence (AI). Prof. Blatz, you’ve dedicated a large part of your life to dentistry and have received numerous teaching and research awards. What inspired you to start using digital technology in your clinics, and how happy are you with the results? Innovative clinical protocols, new technologies and ad- vanced treatment concepts that have a positive impact on patient care have always been at the center of my work, going back to my time at the University of Freiburg in Germany. A strong quest for clinical excellence and an excitement about new technological developments and materials, paired with a deep passion for teaching and research, motivated me to engage in digital den- tistry and material research early on. However, I am not someone who always has to have the “latest and great- est” tools out there. For me, these tools need to provide 08 2 2021

| opinion In late 2019, we opened the Digital Design and Milling Center, a state-of-the-art facility featuring chairside digital technologies including scanners, design computers, mill- ing machines and ceramic furnaces. In this center, there is a designated dental technician who assists dental students with the design and fabrication of restorations. Novel learning technologies and pedagogies that recog- nise students’ learning styles and preferences are also part of the digital innovation initiative. The PDM learning technol- ogy team, which I founded and supervise, includes curricu- lum designers and learning technology experts. The team is responsible for the development of blended e-learning/ online curricula and continuing education courses, digital course manuals (iBooks), videos and modules for blended learning, examination software, MOOCs (massive open on- line courses) and “gamification” tools and for the integration of AI, virtual reality and haptic technologies. Virtual reality dental training simulators have been part of our educational programmes for many years. The use of our Digital Design and Milling Center has been tremendous and exceeded even my wildest expectations. In fact, we are now fabricating between 70 and 80% of single-unit restorations from our student clinics with chairside CAD/CAM technology! What are some of the state-of-the-art tools, tech- niques or software that you’re using in the School of Dental Medicine, and how do they facilitate your work and that of your students? The laboratory-based CAD/CAM Ceramic Center features multiple face and model scanners, three industrial five-axis milling machines that can mill a full spectrum of materials and types of restorations, and multiple sinter furnaces. There are several computer stations with professional 3D design- ing software that can design and fabricate pretty much any type of restoration, from single-units to tooth- and implant- supported full-mouth reconstructions. The centerpiece is newly developed virtual treatment planning software that produces digital wax-ups in a timely and predictable manner. “AI will soon become critical in aesthetic and functional planning and design and material selection, customised for each patient.” You’ve been actively involved in the initiative since Day One and have contributed greatly to its success. What are you most proud of, and did it live up to your expectations? Definitely, I am most proud of our great team, staff, faculty and students. Despite initial hesitations about digitalising our workflows, undergoing intense training helped us realise that these tools make our work easier and more predictable. You cannot push people into digital dentistry, but you can show them why and how to use it and what the real benefits are. It appears that the COVID-19 pandemic has given digi- tal dentistry, especially chairside restoration fabrication, a great boost. In order to limit the number of times one has to change protective gear and clean the treatment area, dental professionals now carry out more procedures in one longer appointment. This means that it is now possible to fabricate indirect restorations in one such appointment. Additionally, the reduction of laboratory expenses is signif- icant. However, the clinician can still choose to send the intra-oral scan files to an outside laboratory, so all previous options are still available. The Digital Design and Milling Center for in-office CAD/ CAM technologies features 12 design computers and various software programs for planning, designing and milling restorations. There are ten high-speed milling ma- chines and eight ceramic furnaces for firing and finishing restorations. Students learn to select, mill and finish the materials for their patients’ restorations. Currently, we have 17 intra-oral optical scanners throughout the school’s clin- ics, and we are expecting to receive more equipment soon, some of it updated. Our goal is to scan every patient who comes to our clinics and to eliminate preliminary alginate impressions for the diagnostic cast. To that end, both centers are equipped with new 3D printers. We also incorporate digital files into elec- tronic health records. This has various advantages, includ- ing the space-saving storage of diagnostic models and the fabrication of an identical restoration in the event of failure. As a university that distinctly focuses on the sciences, all of the above facilities, tools, workflows and materials are being heavily used for research. Our studies cover the entire spec- trum of modern restorative dentistry and CAD/CAM technol- ogy, with a special focus on the physical, optical and biologi- cal properties as well as the manufacturing of new materials. Students and residents engage greatly in our research ac- tivities, as evidence-based dentistry plays an integral role in our education, training, treatment planning and clinical care. When entering our programmes, every student receives an iPad already equipped with the necessary documents, ap- plications, software and files. One of these applications is dedicated to digital smile design in order to allow students to learn about dental and facial aesthetic parameters and, ultimately, include these in the treatment planning process, so that they are able to share planned smile designs and 10 2 2021

Many of us are somewhere between learning new techniques, integrating these into workflows, being successful and offering the highest possible benefit for the patient (Fig. 1). For many years, digitisation in dentistry progressed with chairside dentistry, which is still connected to the CEREC system (Dentsply Sirona). Today, digitisation in dentistry means being perfectly in time in terms of workflows, (wo)man power and use of machines. Only the best possible balance of all the technical components allows the dentist to deliver a restoration within the planned time. And it is not only the dentist’s time which counts; demanding patients have the highest expectations regarding how little time they will spend in the practice. Acceleration of software, “saving clicks”, was one of the issues which seemed to be a guarantee of greater speed, while production time was a constant. It meant for the dentist and the dental assistant in many cases hurrying between treatment rooms and the in-office laboratory. In order to bridge the time between processing and post-processing, patients have to wait in the practice (or go out for a short walk), while the dentist takes care of another patient, is attending to an emergency case, is in the hygiene room or is finishing the crown her- self or himself. Fig. 1: An intense workflow in the dental office might be overwhelming. The last few years have been characterised by enormous technical progress in dentistry, especially with regard to digi- tisation. However, the vast majority of processes in dentistry are just the translation of analogue processes into digital ones. The main goal behind all efforts it seems is making treatment more comfortable for the patient and faster for the dentist. Depending on the different practice structures, dentists reach this goal with more or less investment in new tech- In 2018, the Slow Dentistry movement arose in Switzerland and demanded, for example, longer appointments to allow for sufficient hygienic measures, treatment and patient care.

A master crown was scanned (CEREC Primescan, Dentsply Sirona) and reconstructed in BioCopy mode in CEREC Software 5.1 (Dentsply Sirona) to copy the mas- ter crown design, and KATANA Zirconia Block STML was milled in the CEREC MC XL milling unit (Dentsply Sirona). The 24 crowns were high-speed-sintered at 1,560 °C for 19 minutes (CEREC SpeedFire); the sintering parameters were generated automatically during milling. Translucency was measured in geometric specimens of 1 mm in thick- ness made out of the different layers of zirconia materials and lithium disilicate within the polychromatic zirconia as well as in comparison with IPS e.max CAD LT. We found that all the zirconia groups showed a higher frac- ture load than lithium disilicate initially and after ageing sim- ulation and that the high-speed-sintered KATANA Zirconia STML showed a higher fracture load after chewing simu- lation than initially but a lower Weibull modulus (Table 1).1 We also found that lithium disilicate was more translucent than the zirconia material in this research (Fig. 3).1 Properties of the advanced lithium disilicate CEREC Tessera Since March 2021, another lithium disilicate material has been available for CEREC users: CEREC Tessera is a strong glass-ceramic with 700 MPa biaxial tensile strength. The block is made of a new material that includes virgilite, a lithium aluminium disilicate that makes up about 10% of the volume. New virgilite crystals form during firing and are embedded in a zirconia-enriched glass matrix.2 The post- milling processing requires glazing and in the preheated CEREC SpeedFire furnace (400°) takes only 4.5 minutes. To the author’s knowledge, there is no publication compar- ing optical or mechanical properties of other lithium disili- cate products (IPS e.max CAD) or lithium silicate (Celtra Duo, Dentsply Sirona).

| study Digital workflow for colour verification of indirect anterior restorations Dr Les Kalman, Canada 1 2 3 Fig. 1: Zirconia veneer facial surface. Fig. 2: Zirconia veneer internal surface. Fig. 3: Zirconia veneer proximal surface. Introduction Dentistry is experiencing a continuous and rapid evo- lution into a digital platform,1 as an increasing number of clinic procedures can be completed with the aid of technology.1 Digital dentistry provides many benefits to the clinical workflow, including increased efficiency,2 reduced environmental impact,3 and a more acceptable approach for the clinician and patient,2 especially in light of specific restrictions related to COVID-19.4 Combining the digital dentistry platform with recent ad- vances in dental materials provides improved predict- ability of procedures,5 especially in challenging anterior aesthetic cases. Zirconia has traditionally been used in posterior regions6 owing to its very high strength.6 However, zirconia may also be used in the anterior regions for veneers (Figs. 1–3)7 and crowns (Figs. 4–6), as it exhibits high strength and translucency and re- quires minimal preparation.7 Although many aspects of dentistry have benefited from a transition to digital methods, others remain grounded in dated and historic approaches.8 One specific clin- ical procedure is that of colour verification of indirect restorations. Digital dentistry can facilitate virtual impressions, digital design and output, but the verification of colour is 7 4 5 6 Fig. 4: Zirconia crown facial surface.

This subjective approach can prove timely and costly, as it is a procedure that requires chair time and possi- ble local anaesthetic. If the colour is inaccurate, which occurs about 49% of the time in dental schools,9 it can prove frustrating for the clinician and patient. This investigation presents a novel digital workflow (Fig. 7) for the colour verification of indirect anterior “Colour verification was completed using a novel digital workflow. The software (Smile Shade) was opened on an iPad and paired with the wireless Bluetooth sensor.” 18 2 2021 restorations, specifically zirconia veneers and anterior crowns, as an in vitro study. Materials and methods Master models for a single veneer for tooth #22 (Fig. 8) and full crowns for teeth #11 and 21 (Fig. 9) were digitally scanned (Straumann CARES 3, Straumann). A veneer for tooth #22 and full zirconia crowns for teeth #11 and 21 were digitally designed using dental software (exocad) by a dental tech- nician and exported as STL files (Figs. 10–12). The files for the veneer for tooth #22 and the crown for tooth #21 were transferred to a commercial laboratory (Glidewell) for the fabrication (Figs. 13 & 14; BruxZir Esthetic, Glidewell). The laboratory prescription requested six identical units of the tooth #22 veneer (Fig. 15) and six identical units of the tooth #21 full crown (Fig. 16) to be fabricated and finalised in Shade A1 with graduations identical to the VITA shade tab. Once completed, the units were shipped, unpackaged and assessed. Colour verification was completed using a novel digital workflow (Fig. 17). The software (Fig. 18; Smile Shade) was opened on an iPad and paired with the wireless Bluetooth sensor. The sensor contacted the tooth and recorded the colour and then transmitted the informa- tion to the iPad, which provided a colour description. The entire process required about 3 seconds to complete (Fig. 7). The determination of colour was ex- pressed in cyan, magenta, yellow and key (CMYK); red, green and blue (RGB); lightness, redness vs greenness, yellowness vs blueness (LAB) and hexadecimal num- bers (HEX) which are all different means of describing colours objectively. The shade tab was colour identified using the novel digital workflow. The same procedure was applied to identify the colour of the six tooth #22 veneers and the six tooth #21 crowns. Results The colour identification of the VITA shade tab is dis- played in Figure 19. The colour identification of the six zirconia veneers is displayed in Figure 20 and the six anterior crowns in Figure 21.

Fig. 23: Zirconia veneer with shade tab and no LED light. displayed mild variability between the six units and vari- ability with the shade tab. The colour of the six crowns were quite consistent, but varied from the shade tab. Discussion The digital workflow indicated a difference in colour be- tween each veneer, between each crown and between the indirect restorations and the shade tab. Whether the colour difference is of clinical significance will depend on the decision of the clinician and patient. The identification of colour in dentistry can be a chal- lenging endeavour, as it is affected by several variables.10 Even external light may influence the colour. Figures 22 and 23 depict the zirconia veneer next to the shade tab, one with an LED ring light and one without, respectively. Similarly, Figures 24 and 25 depict the zirconia crown next to the shade tab, one with the LED ring light and one without, respectively. Although the same shade tab (A1) is present in all four images, the colour of the shade tab and the restorations may appear dif- ferent. The novel digital workflow functions with a very high dynamic range micro colour sensor that has an auto- matic temperature control and an inter-device repeat- ability of < 1 ∆E, (∆E represents the distance between two colours), which illustrates that the software can detect very subtle changes in colour. It is a very accurate method for colour identification and verification, using a different method to describe dental colour with 24 25 Fig. 24: Zirconia crown with shade tab and LED light.

| case report Magical All-on-4 Dr Stanko Miletic, Dr Ivan Miletic & Pavel Metelka, Croatia & Czech Republic 1 Fig. 1: Successful treatment results from the past with our aesthetic implant workflow. Surgeon Stanko Miletic takes care of an effective implant treatment as a base for the prosthodontic treatment per- formed by dentist Ivan Miletic, who also registers the indi- vidual information of the patient for the dental technician Pavel Metelka, who digitally produces the final restoration. The digital data is stored in case of future patient services. We have been performing full-arch or full-mouth resto- rations in this manner for the past eight to ten years. Just in the past three to five years, we have treated over 400 cases together in this way, most of them with the All-on-4 technique with an immediate loading protocol (Fig. 1). As material, we primarily use Ceramill PEEK White (Amann Girrbach) for the substructures, combined with single zirconia crowns made from Zolid FX Multilayer (Amann Girrbach). The crowns are cemented to the PEEK substructure, and for the anterior region, we always perform a little cut-back for an aesthetic flourish. The gingiva is layered with pink composite. In some cases, we use a se- lective laser melted substructure veneered with composite. In this article, we will present a prosthodontically driven case to demonstrate the importance of team commu- nication between surgeon, prosthodontist and dental technician. Only good team communication leads to a functional and aesthetic result. The case involved a full-mouth All-on-4 rehabilitation with immediate loading using screw-retained bridges with a PEEK substructure combined with all-ceramic single crowns. We will present each phase of the aesthetic implant workflow, from sur- gery to prosthodontics and the laboratory work. Initial situation The patient came to our office with a denture in the max- illa which he had had for more than 30 years.

Prosthodontic planning As soon as the surgery is finished (Fig. 6), we capture the impression, height and facebow registration immedi- ately. We consider our design of the definitive restoration in the so-called alpha bridge, the initial—temporary— design (Fig. 7). This part is very important, as we can test the new height, function and aesthetics of the first de- sign. We use Ceramill TEMP Multilayer (Amann Girrbach) for the alpha bridge; everything is done at the level of the multi-unit abutment. After three to four months, we capture a digital pan- oramic scan for control and perform a percussion test of the dental implants. We then start to plan the de- finitive restoration. One important thing we consider in the planning is the feedback from the patient regarding the alpha bridge. We perform the bite and facebow registration of the alpha bridge with the Artex facebow (Amann Girrbach; Fig. 8). Afterwards, we send the temporary bridge and bite and facebow registration to the dental laboratory for articula- tion and scanning. Creating pictures of the patient is a great way to check the planned final aesthetics on the screen (Fig. 9). We first go through the aesthetic and functional checklist with the patient and review the aesthetics later in the pic- tures. Adjustments are made in the design software as needed to gain the optimum aesthetic result. After the CAD is done, we proceed to milling the beta bridge in the Ceramill Motion 2 (Amann Girrbach) using Ceramill TEMP Multilayer. We use the beta bridge as a final try-in before we start to design the definitive restoration. Also, in this process step, we take pictures of the patient and ask him or her about the look and feel of the adjusted restoration. If everything is fine, we proceed with the definitive restoration. Definitive restoration After the try-in of the beta bridge has been successful regarding function, aesthetics and, of course, patient approval, we start to design the definitive substructure using Ceramill PEEK as material. When designing the substructure, the basis for the later zirconia crowns is also created at the same time (Fig. 10). The substructure needs to be designed 1–2 mm deeper than we expect 9 Fig. 9: Aesthetic check with patient pictures. 24 2 2021

CAM software (Amann Girrbach) and Ceramill Motion 2/ Mikro milling machines. For the crowns, we use the highly aesthetic zirconia material Zolid FX Multilayer (Fig. 12). Since it was a full- mouth rehabilitation and we did not have to orient our- selves on existing residual teeth, we decided to produce the crowns in Shade A2/A3. Zolid FX Multilayer brought us lifelike colour shades, adequate transparency and acceptable bending strength. For the posterior region, we use full-contour crowns, and in the anterior region, the crowns have been slightly anatomically reduced (cut-back) to make space for ceramic veneering (Fig. 13). To achieve the highest possible level of detail right after milling, we chose the HD milling strategy. With that strategy, the fissures are finished with a 0.3 mm bur. The greatest benefit of PEEK-based screw-retained bridges is that we can place the crowns directly on the model during veneering. Because we used the cut-back library developed by dental technician Knut Miller in the CAD, it is easy to veneer the anterior region and at the same time keep a constant shade for all the crowns. The veneering process gives us the freedom to play with the aesthetics, transparency, colours and natural look of the patient’s smile. Since we knew from the interviews with the patient that he was very satisfied with the shape of the anterior teeth and the height of the smile line from the temporary bridge, we used this shape as the base for the veneering. For that reason, we copied the tooth shapes from the tempo- rary anterior crowns in the CAD software and milled the crowns afterwards in Ceramill Wax White (Amann Girrbach; Fig. 14). In the second step, we produce a silicone key, which makes the veneering process as easy as it can be. It is an efficient and predictable aid. Digital systems have many benefits corresponding to manual process steps that we can use for our reliable workflow. After veneering, we need to finally check all the details of the crowns before we cement them on to the substructure (Fig. 15). | case report 14 15 Fig. 14: Milled wax crowns and a silicone key as assistive devices for the later veneering process. Fig. 15: Final check of the Zolid FX Multilayer crowns. the final margin. We will overcover the cervical margin of the crowns with gingiva in the final step. The minimum height of the substructure needs to be 7–10 mm and the width 5–8 mm and can contain cantilevers, which can be no longer then the distance between the two neighbouring implants. The milled result on the Ceramill Motion 2 DNA is smooth and precise thanks to the great milling strategies (Fig. 11). In this case, we used Ceramill PEEK White, which helped us keep the final colour of crowns without using any opaquer after luting them on the substructure. The milling strategy can be wet or dry, but only on a five-axis milling machine. By choosing the fine strategy for under- cuts, the five-axis milling on the outside shape is precise without any manual correction. For fitting on the implants, we decided to use the InCadCam solution. For multi-unit abutments, it is the best choice for a direct fit in combination with PEEK in the Ceramill Match 2 16 Fig. 16: Veneering of gingival parts with composite. 26 2 2021

| case report Achieving anatomical shape, support and colour with an Atlantis patient-specific abutment in gold-shaded titanium: A case report Dr Fernando Rojas-Vizcaya, Spain 2 3 Fig. 1: A vertical fracture of tooth #46. On probing, a distal narrow isolated pocket measuring more than 15 mm in depth was detected. Fig. 2: On the radio- graph, a radiolucency along the distal wall of the distal root with the typical J shape seen in vertical root fractures could be observed. Fig. 3: Tooth extraction was performed without damaging the alveolar walls. The socket was scraped and sutured without using grafting material. The aim of this case presentation is to show a step-by- step workflow with Atlantis patient-specific abutments. The case is of a 36-year-old patient with a vertical frac- ture of tooth #46 who was referred to our clinic. The treat- ment plan was to extract the tooth and replace it with a dental implant using a conventional placement and load- ing protocol. The challenge was to restore the position of the gingival contour and the interproximal papillae to have the appearance of a natural tooth. In order to achieve a long-term, natural-looking result, an Atlantis abutment (Dentsply Sirona) was selected to provide the optimal anatomical shape, support and colour. 5 8 6 9 28 2 2021 1 4 7

Fig. 2: Design of the healing abutment and definition of the crown emergence profile. (All images: © Dr Steffen Herzberg, Zahnärzte am Himmeloh, Witten) The replacement of missing teeth with dental implants is an established therapeutic approach that allows pre- dictable results if correctly indicated. The fact that dental implants osseointegrate is no longer questioned. Today, the primary focus is on preserving the peri-implant tissue structures and increasing patient comfort while reducing morbidity and treatment time as far as possible. Camlog has established a new workflow in implant therapy with DEDICAM Services for its new customised, anti-rotation PEEK healing abutments and PEEK impression copings, which are designed on the basis of patient- specific emergence profiles and manufactured from the same data set as part of the CAD/CAM process. The individually tailored PEEK healing abutments and PEEK impression copings, which are identical in sub- gingival design, enable preoperative, intra-operative and postoperative procedures for the shaping and transfer of peri-implant soft tissue—for which intensive interdisci- plinary exchange between the treating teams is an advan- tage. The tissue-friendly PEEK material and the optimis- ation of the anatomical emergence profiles offer clinical benefits in that there is no additional soft-tissue manipula- tion required and the shaped profile can be transferred to the master cast in a precise manner. A stable soft-tissue cuff protects and nourishes the peri-implant bone and creates the basis for a predictable aesthetic outcome of the definitive restoration. Customised PEEK healing abutments and impression copings for Camlog implants The individualised PEEK healing abutments and impres- sion copings will initially be available with the connection for CAMLOG SCREW-LINE and CAMLOG PROGRESSIVE- LINE implants. They are milled in a CAD/CAM procedure from solid PEEK rod material with a diameter of 10 mm. Milling PEEK requires comprehensive knowledge of material processing and quality assurance, since the patient-specific products demand the highest precision in manufacture. PEEK has been in clinical use in implant dentistry for many years and is predominantly used to fabricate provisional restorations. The PEEK healing abutments are approved for use in the oral cavity for a duration of 180 days. They can be ordered individually or as a set including an impression coping. The posts are available for use with either the open- or the closed- tray technique. Utilising the libraries provided for the CAD software from 3Shape and exocad, registered DEDICAM customers can design the healing abut- ments themselves and order their subsequent manu- facture. Based on the same data set, the impression copings can be manufactured upon request as well. 30 2 2021

Fig. 8: The definitive restoration with a stable and anatomically formed peri-implant mucosa. design can additionally be used without modification to design the definitive abutment. If changes are required, the current soft-tissue situation can be recorded using an intra-oral scan taken from the implant shoulder. However, for complex rehabilitations with bridge restorations on the implants, analogue impression taking with the PEEK impression posts has been proved to be advantageous. The partially digital way The partially digital way is characterised by collaboration between the surgeon, referring dentist and dental technician. In coordination with the prosthodontist, the surgeon places the implants and scans them prior to covered healing. When the implants are exposed, the customised healing abut- ments are employed to anatomically shape the peri-implant soft tissue. After tissue healing, the prosthetic restoration commences in the practice of the referring dentist. There, the dentist deals with a perfectly shaped mucosa, which is transferred to the laboratory for the fabrication of a master cast by means of the individual impression copings in an analogue procedure without any additional effort. Based on the preferences of the dental technician, the implant resto- ration is then fabricated in either analogue or digital fashion. Outsourcing to the production centre— a mix of analogue and digital The surgeon takes an implant impression or scans the implant position intra-operatively. He sends either the physical models or the scan data together with a situation scan and an opposing arch scan to Camlog. The skilled dental technicians at the DEDICAM Service centre de- sign the patient-specific healing abutment in consulta- tion with the treating clinician and submit a manufactur- ing order for the healing abutment and impression coping to the production centre. There, both are manufactured with high precision and are available in the practice when the implant is exposed in order to obtain the best clinical conditions for an anatomically shaped mucosa. Conclusion With the individual PEEK healing abutments and impres- sion copings, the workflow is flexible and convenient for everyone involved. The virtually designed patient- specific emergence profile can be safely controlled from the time of implant placement until the realisation of the definitive restoration. There is no need to manipulate the soft tissue, as would be the case after removing a stan- dardised healing abutment. An impression coping with exactly the same emergence profile, since it is created from the same data set, prevents the mucosa from col- lapsing and transfers the shaped soft-tissue profile for the fabrication of a form-congruent abutment. The easy handling, the achievement of a predictable result and the reduction of treatment appointments, pain and work steps distinguish this patient-friendly treatment con- cept. The work required for crafting a model or a silicone key for analogue fabrication of individualised impression copings with composite is eliminated. With this treatment concept, surgeon and prosthodontist work closely to- gether with the laboratory and Camlog for the ultimate benefit of the patient. PEEK has established itself in implant therapy as a tissue- friendly material for provisional restorations.1–3 In addition to optimising the mucosa and preserving the alveolar bone, an anatomically designed emergence profile cre- ates the basis for the natural red–white aesthetics of the implant restoration. The use of customised healing abut- ments and impression copings is time- and cost-efficient and a valuable part of a patient-friendly treatment concept.

| industry report KATANA Zirconia—the science behind superior product properties Mathias Fernandez y Lombardi, Germany 1 2 Fig. 1: At Kuraray Noritake Dental, all the powder is produced in-house. Fig. 2: KATANA Zirconia blank ready for milling. Users of dental zirconia are spoilt for choice these days. Countless manufacturers offer zirconia materials that differ in their mechanical and optical properties and in- dication range. What is not apparent at first sight is that the available products also differ with respect to the qual- ity of the CAD/CAM blanks offered. Blank quality is highly dependent on the quality of the raw materials and is af- fected by different aspects during raw material process- ing, pressing and pre-sintering. This has a huge impact on the surface quality, edge stability, fit and processing requirements of milled restorations. Raw material production Pre-shaded dental zirconia typically consists of metal oxides, including zirconium oxide, yttrium oxide and alu- minium oxide, as well as additives like binders and colour pigments or ions. Most manufacturers of dental zirconia obtain prefabricated powder from an external industry partner, the most popular option being Tosoh Corp. In contrast, Kuraray Noritake Dental relies on an end-to-end in-house process. This includes the production and ad- dition of the components forming the company’s innova- 3a 3b Figs. 3a & b: Overview of the recommended sintering protocols.

All the high-level preparation processes, from raw material production to pressing, are responsible for the high edge stability and surface quality of restorations milled from KATANA Zirconia.

| feature “I would love to inspire more women to get involved in digital dentistry” An interview with Dr Alison Simpson, a general dentist from Rothwell in the UK, honoured with the first Smart Integration Award By Dentsply Sirona In November 2019, 24 female dentists from seven nations received Dentsply Sirona’s first Smart Integra- tion Award for visionary treatment concepts. One of the winners was Dr Alison Simpson, a general dentist from Rothwell in the UK. She was honoured with the first Smart Integration Award for sharing her story of success in using the digital workflow. In this interview, Dr Simpson told us about her background, discussed changes in the dental industry and shared her ideas about technology and the future of the dental practice. Since 2019, Dentsply Sirona has been honouring innovative women in digital dentistry with the Smart Integration Award. 38 2 2021

| feature Does digitalisation play a major role in the UK? Do you expect it to move in that direction in the future among dental professionals? Yes, I believe that digitalisation is really about to take off, and I find it an incredibly exciting time to be in dentistry. I am so glad that I am part of the movement. As for dig- ital dentistry, colleagues who do not yet use intra-oral scanners should embrace this technology or they will soon be left behind. Patients are now aware of the ben- efits of digital dentistry, and I think it won’t be long be- fore they seek out the dentists who use digital dental technology. In a society increasingly driven by quick or even instant results, where everyone is becoming their own brand representative, delivering quick results and showing people what their smile could look like is crucial. If dentists are not onboard with this move, they will be left behind. “Digital dentistry, by its very nature, offers far greater rewards to those who approach it with a team mentality.” With concepts like the Smart Integration Award, Dentsply Sirona aims to bring more women’s ideas into the field of dentistry and to create a network for women. There are more and more women dentists and dental students in dentistry, and that trend is continuing. Is this something that you’ve observed personally in the UK? Even when I was at dental school about 20 years ago, there were more women than men in dentistry. I think it’s just taken a while for companies to catch on to that fact. However, what surprises me is that lectures, workshops and digital symposiums are pri- marily male-dominated, even as far as the audience is concerned. I find it worrying that women don’t participate in or even go to these conferences. I always ask my col- leagues why they don’t want to attend. Many of them are just too busy because they are looking after fam- ilies or working only part-time. I would love to inspire more women to get involved in digital dentistry. I find it quite upsetting that many women are not involved in this field. How did COVID-19 affect dentistry and your work in relation to patient care? Did the role of digitalisa- tion change? Does digitalisation now play an even greater role? Like every aspect of life, COVID-19 has had a tremen- dous impact on our clinic and on dentistry as a whole. Since reopening, the focus has been on keeping the staff, the patients and our families safe. This was not only in terms of negating as far as possible any chance of catching the virus but also in terms of making people feel safe in the clinic, so that we could continue to pro- vide our renowned care with minimum stress. My team was flexible and supportive, so I didn’t feel alone in the decision-making. Same-day dentistry treatments were, and are, increas- ingly reassuring for patients, as the volume of traffic through the clinic continues to go down. Patients have reduced both their own and our risk of infection by com- pleting their treatment in one appointment. Additionally, there has been a huge uptake of SureSmile treatment, the whole process of which is digital. In many ways, COVID-19 has accelerated the uptake and acceptance of new digital processes in the den- tal world. We have been able to reduce face-to-face consultations and offer virtual meetings, and patients find these more acceptable owing to increased conve- nience and time efficiency. Do you have any specific goals, either within den- tistry or otherwise related to your career and business? I would like to inspire other dentists, both male and female, to get onto the digital pathway because I have gained so much fulfilment from it. I know from my own experience how much it can enhance a patient’s treat- ment journey. My key piece of advice for those seek- ing to get into digital dentistry is that they should try to surround themselves with team members who have the same goals and desires. Digital dentistry, by its very nature, offers far greater rewards to those who approach it with a team mentality. I wouldn’t be where I am now without the team that I had around me on my digital journey.

| news Dr Janos Vág Dr Janos Vág became a dentist out of necessity, but he would have preferred to have become a com- puter science engineer. However, when it was time to choose his ed- ucational path in 1989, there were few opportunities for engineers. His father, a dentist, suggested that he could make use of his sci- entific and technical interests in dentistry as well, so Vág decided to follow in his father’s footsteps. Indeed, for the past decade, Vág has also been able to combine his interest in computer science with his profes- sion in following the evolution of digital dentistry. Working as a clinical associate professor and head of the conser- vative dentistry department at Semmelweis University in Budapest in Hungary, Vág has established an impressive academic track record, having published 49 articles— with 370 citations—in peer-reviewed journals. Dr Janos Vág believes that industry standards could help make intra- oral scanning solutions easier to compare, and studies measuring their effi cacy more helpful and reliable. (All images: © Semmelweis University) 42 2 2021 “There must be academic proof that (...) digital dental tools are really reliable” Mari Koivunen, Finland In addition to his academic research, Vág has a great deal of clinical experience. For five years, he worked at a dental practice, focusing only on clinical work. Today, he practises as a conservative dentist with an emphasis on restorative dentistry and endodontics. He also performs oral surgery and prosthetic treatments—it is common in Hungary for dental specialists to cover larger treatment areas. Digital dentistry makes work fun Although digital dentistry has been an industry buzzword for several years now, Vág said that going digital is still not on the agenda for many dentists. “Using digital workflows will completely change the work at the dental practice,” he noted. “However, most dentists are still not taking any steps to becoming digital dentists. This is not only the case in Hungary, but in the US and on a global scale as well.” He added: “In dentistry, we should be ready for new things that might not be beneficial in the first few months, but are good fun and make our work much better. Through these investments, dentists can also gain more patients, who might never go back to their previous dentists if they lack the technology.” Starting from September, undergraduate students at Semmelweis University will learn how to make inlays, onlays and single crowns using an array of CAD/CAM solutions that include an intra-oral scanner, design software and a milling machine. The goal is to teach students how to pre- pare a tooth for scanning and digital restorative design, according to Vág. “Fortunately, digital dentistry is not the future; it is the present,” he said. The need for academic proof While some dentists are not even considering going digi- tal, others are ahead of the existing academic research in their use of digital dentistry. They immediately try out new technology and find out by themselves how to make best use of it. “Some dentists already manufacture, for example, complex bridges using only digital impressions as the basis,” Vág said. “At the same time, they wonder why we are even study- ing the scanners, because they have no issues with their treatments whatsoever. But if you want to get the majority of dentists to go digital, there must be academic proof that

| interview “The future is certainly looking bright” An interview with Heikki Kyöstilä, chairman and CEO of Planmeca By Claudia Duschek & Jeremy Booth, Dental Tribune International the design and ergonomics of these products could easily be improved. That is why I decided to set up my own business. I thought, “Why not start manufacturing products of our own?” The beginning was financially tough, since Finnish banks did not easily grant loans to start-up companies. I had to sell my sailing boat—my only possession, back then—in order to raise an initial capital of 5,000 Finnish marks, which is roughly the equivalent of €7,000 today. However, having realised that the Finnish dental market simply was not big enough to build upon, I immediately aimed for the international market. Today, there are only around 4,000 dental professionals in Finland, whereas the number is close to 2 million globally. Luckily, I had the opportunity to take part in the International Dental Show in Munich in 1971. I exhibited my first products at the fair—an ergonomic dental stool and an instrument cabinet. One of the biggest challenges in the beginning was sim- ply putting Finland on the map and getting the word out about Finnish dental products. It was not only our com- pany that was unknown but also our country of origin. Many of our customers had no idea where we were located; however, little by little, we began to gain a foot- hold in the industry. What have been the greatest milestones in the his- tory of Planmeca? Businesswise, I would say that the achievement that I am personally the proudest of is that of having se- cured the largest individual sales deals in the history of dentistry. Planmeca entered the US market in 1983 with the sale of 10,000 patient chairs, and we delivered over 1,000 dental units to Saudi Arabian dental institu- tions in 2012. In terms of technological innovations, one of our most significant milestones was the development of the Planmeca Dimaxis all-in-one software concept in the 1990s. It really was a groundbreaking and bold in- novation at the time and was launched long before the term “software ecosystem” became a buzzword. Heikki Kyöstilä founded Planmeca in 1971. As the company marks its 50th birthday, Dental Tribune International asked Kyöstilä if he had ever considered selling the successful dental business, to which he replied: “Quite frankly, no.” (All images: © Planmeca) This year, Planmeca is celebrating 50 years of con- tributions to modern dental practice. Many of our read- ers will know Heikki Kyöstilä, chairman and CEO of the Finnish dental manufacturer. Kyöstilä has been cred- ited with putting Finland on the global dental map, and he has remained humble and customer-focused even as Planmeca set sales records and grew into a house- hold name in dentistry. Dental Tribune International spoke with Kyöstilä to find out more about Planmeca’s achievements and about the man who founded one of the largest dental manufacturers in the world. Mr Kyöstilä, you founded Planmeca in 1971 as a small-scale business; however, you quickly ad- opted a global approach. What was the rationale behind the founding of the company and what have been the greatest obstacles so far during its development? Back in the 1960s, when I was working as a sales rep- resentative for a Finnish dental supply company, almost all dental products sold in Finland were imported. I re- alised that—especially when it came to patient chairs— 44 2 2021

| interview Heikki Kyöstilä has been in the healthcare business since the 1960s. “For me, Planmeca is a way of life and I certainly do not see retirement as an option anytime soon. I want to continue to stay close to my customers and staff, and I want to be involved in everything that is going on in the company. Working together with dental professionals towards a mutual goal of better patient care is truly rewarding.” “(The) need for dental care has certainly not diminished despite the changing world.” No one could have imagined the events of 2020—it was a year unlike any other. They say that necessity is the mother of invention, and we certainly had to discover new ways of working and of interacting with our cus- tomers. When the pandemic began, we quickly real- ised that we must move customer interactions online. As a starting point, we organised a full series of webi- nars in several different languages as part of our new 46 2 2021 Time to Learn training concept. These webinars have allowed our customers to further improve their exper- tise and to make the most of their Planmeca equipment. Webinars have proved to be an effective way for us to cover highly topical themes such as infection control. We have already organised over 100 webinars in differ- ent languages. All in all, we have been lucky that many of our custom- ers have been able to keep their services open most of the time—at least partly—and the need for dental care has certainly not diminished despite the chang- ing world. Before the pandemic, Planmeca participated in thousands of dental events, trade fairs and con- gresses worldwide. How have you managed to build and maintain relationships with your customers and partners over the past months? Indeed, it has always been very important for us to meet customers at events around the world and, es- pecially, to welcome guests here in Helsinki. Before the pandemic, thousands of dental professionals visited our headquarters every year. This has not been possi- ble during the pandemic and we have had to arrange these meetings virtually, which has actually brought us even closer to our customers in many ways. For example, we took our popular Digital Dentistry World Tour online for the first time ever. It was a com- pletely new type of dental event that was streamed in eight languages. Thousands of viewers from over 100 countries were able to tune in at the same time, and it was quite exciting to meet so many of our customers at once. What lies in the future for Planmeca, and where do you see the company’s greatest potential for growth in the near term? The future is certainly looking bright. We have several interesting dental and medical projects underway in our R & D department. We continue to deepen our knowledge, expertise and involvement in different specialty areas, such as orthodontics, medical im- aging and new 3D applications. This will allow us to explore new technological possibilities and business opportunities. At the age of 75, is retirement an option for Heikki Kyöstilä? For me, Planmeca is a way of life and I certainly do not see retirement as an option anytime soon. I want to continue to stay close to my customers and staff, and I want to be involved in everything that is going on in the company. Working together with dental profession- als towards a mutual goal of better patient care is truly rewarding.
