editorial | Dr Scott D. Ganz Editor-in-Chief Are we there yet? This is a common question that arises when discussing advances in technology and whether we have arrived at a point where progress has stabilised and brought us to a satisfactory and stable state. It seems that no matter how fast our computer is, wait a week and there will be a faster version on the market. How about the recent advances in laptop computing power? Is 32 GB of RAM enough to make exocad fly, or do we need 64 GB or even 128 GB? There was a time when a mobile phone did not even have a camera, then there was one which took good low- resolution images and now the iPhone 15 Pro Max has an A17 Pro chip and a main camera that can capture images of up to 48 MP! Who would have guessed that our phones would be able take 4K video good enough for making movies? How much memory or storage capacity will we need to have to store not only all of the patient images we take but all of our family videos? How about our intra-oral scanners? We love our scanners for their flexibility over conventional analogue impressions for crown and bridge or implant restorations. We were so happy to have the ability to digitise the mouth that speed was an afterthought, accuracy being the goal. Then, of course, we realised that time was money, so we pushed the limits to achieve scanning of an arch at record speed! Was that enough? Not while tethered with a cord! Many scanners have made the move away from the cord to a wireless solution and have not suffered a reduction in speed or accuracy. One of the major catalysts for the acceptance and adoption of our digital workflows has been 3D printing. At first, we had to send our STL files to a large commercial 3D printer because 3D printers were too expensive for everyday clinicians to own. The bringing of 3D printers to the masses was a huge catalyst because we could now have technology right in our private clinic, ready to print models for crown and bridgework or for surgical guides to facilitate implant placement. We could print a mandible for educational purposes or a full skull if the print plat- form was large enough. It was not long before the same problem of speed arose. Stereolithography was slow. Most printing happened over hours not minutes. The race for speed then became a focus for the marketplace, and printers became faster and faster without sacrificing accuracy. Part of the speed problem was not just the architecture of the printers but the resin utilised. New resins for crowns and dentures were introduced to the market. It was soon apparent that, if a laboratory was going to move to 3D printing, it would also need more than one printer, one for the crown and one for the model, which would be fabricated using another resin. We can all agree that technology is wonderful, essential and helpful for our daily practice of dentistry. We can also agree that, if we blink, we may miss the latest innovations for devices and ancillary components of today’s digital workflows. So, are we there yet? Our industry is on the path to integrating technology into most aspects of dental sciences, and while we might reach amazing milestones, we may never be satisfied with the current state of the art. I am therefore personally pleased that we continue to march forward and excited that many of these advances will continue to be showcased within the pages of our publication, digital. Enjoy our current issue! Respectfully, Dr Scott D. Ganz Editor-in-Chief 03 2 2024

news | except in Germany, where survey results showed that procedure utilisation and dentist outlook had improved. Sharing more of the company’s market intelligence, Campion said that dentists in Australia continued to exhibit some negative sentiment about market con- ditions, that patient volumes had declined in Japan and were stable in China and that Canadian patients seemed to have delayed treatment during the period, owing to the phased roll-out of the country’s new dental plan. “We are taking a cautious stance here with the macro uncertainties that continue to impact parts of our business, most notably imaging,” Campion said. Glenn Coleman, Dentsply Sirona’s chief financial officer (CFO), alerted investors to the company’s first-quarter highlights—53% sales growth in China, a 14% increase in global clear aligner sales and 9% growth in CAD/CAM— all of which were offset by declines in sales of imaging equipment. Global sales of SureSmile clear aligners in- creased by 9% and the company’s direct-to-consumer aligner, Byte, grew by 18%, bucking a negative trend in the demand for at-home aligner systems. Align Technology ships more teen cases than ever before The maker of Invisalign had the first quarter it needed after a run of disappointing results in 2023. Sales at the company reached US$997.4 million, a 5.8% year-on-year increase. Clear aligner revenues, at US$817.3 million, were up by 3.5%, and those from imaging systems and CAD/CAM services increased by 17.5% to reach US$180.2 million. First-quarter shipments of clear aligners increased by 2.4% year on year to reach 605,060. At 199,200, Align’s teen shipments were up by 5.8% and greater than in any quarter previously. CEO Joseph Hogan told investors that Align had achieved a number of milestones during the period, such as the acquisition of Cubicure, a leader in direct 3D-printing solutions, which Align hopes will revolutionise its produc- tion process. The company also launched the Invisalign palatal expander system in the US and Canada, and Hogan said that it was one of the most significant inno- vations in the company’s 27-year history. Straumann Group posts 15% organic growth Yang Xu, CFO of Straumann Group, told analysts in the company’s earnings call that the multinational had had a “solid quarter”. Sales of CHF643.8 million (€660.8 million*) represented year-on-year growth of 8.1%, or 15.1% on an organic basis. “We still see headwinds in the doctor-led direct-to- consumer [clear aligner] business.”— Guillaume Daniellot, CEO, Straumann Group Straumann had minor year-on-year revenue declines in the Europe, Middle East and Africa (EMEA) and the North America regions, where sales decreased by 0.9 and 2.3%, respectively. However, all regions returned organic sales increases: 5.2% in EMEA, 3.7% in North America and 11.5% in Latin America. Straumann banked CHF130.8 million from sales in the Asia Pacific region, representing a 63.7% increase in revenue and an 82.0% increase in organic sales. This strong year-on-year growth is partly due to the company’s comparatively weak performance in the region in the first quarter of 2023. Guillaume Daniellot, CEO at Straumann, remarked that the company’s performance in China had been a high- light of the quarter. He said that Straumann’s business in the burgeoning dental market continues to grow, having gained momentum last year, when the company doubled its implant shipments compared with 2022. EMEA remains Straumann’s largest market, and re- gional sales to clinicians of the ClearCorrect aligner brand increased by double digits during the period. ClearCorrect performed well in the North America and the Asia Pacific regions, contributing to strong ortho- dontic sales in established markets such as the US, Australia and Japan and in emerging markets such as Vietnam and India. “On the challenging side, we still see headwinds in the doctor-led direct-to-consumer business, namely DrSmile,” Daniellot said, citing persisting macroeconomic challenges among consumers. He said that Straumann had shifted from paid marketing to organic demand generation for DrSmile and had achieved 3.7% growth in North America, despite a “softening market”. Envista says patients will prioritise dental care In Amir Aghdaei’s last earnings call as Envista CEO, and his successor’s first, the outgoing chief said that the quarter had proved challenging and resulted in modest 09 2 2024

trends & applications | comfortable with AI-written blogs, newsletters and articles (but check the facts). Let us look into current and future applications of AI in dentistry. At BDCDS, I will be considering these possi- bilities. I would like to take a low-altitude swoop over the dental AI landscape and get my audience thinking about how they can embrace these potential uses: – new patient enquiries handled by AI capable of answering initial questions and able to triage the patient to the right clinician; – calendar management by AI to maximise the pro- ductivity of fee-earners and negotiate convenient appointment times for patients; – initial assessments by AI that will speed up the diagnostic element of patient consultations; – treatment planning by AI that will combine the sales element of the conversation with precise itemisation of the treatment pathway; – AI smile design, allowing patients to see a realistic improvisation of their post-treatment appearance and functionality; – guided implant surgery with AI acting as an autopilot to the clinician and increasing accuracy of placement; – dental office administration utilising AI to streamline every aspect of financial monitoring; – AI-driven marketing activities that will automate external, internal and inbound marketing systems; and – compliance checked by AI regularly to ensure that your team stays in their lane. For all of that, I can imagine a modern Luddite re- enacting my 70s pub scene, arguing: “AI will never replace people in the business of dentistry or the delivery of clinical dentistry.” Canute was wrong, so was Bracegirdle, and so has every critic or doubting Thomas been ever since. I doubt things are going to change—because everything is about to change. Be prepared. about Chris Barrow has more than 50 years of work experience and has been active as a consultant, trainer and coach to the UK dental profession for over 25 years. His main professional focus is through his Extreme Business company, providing coaching and mentorship to independent dentistry around the world via virtual consultancy, practice visits, a workshop programme and an online learning platform. His blog, Thinking Business, enjoys a strong following. During the COVID-19 pandemic, Barrow created the Regeneration Coaching Programme to help practices to survive lockdowns and to bounce back higher after their return to work. More information on his work can be found at www.coachbarrow.com. 21 2 2024 Quite apart from his Dickensian surname, which might have betrayed an ancestral reluctance to change, Bracegirdle was not impressed by the technology. Looking back from half a century later, I think it is fair to say that he was rather like Canute the Great, King of England in the eleventh century, willing the waves of progress to reverse and getting wet feet. This experience was a precursor to a lifetime of listening to technology laggards, who at every stage of digital evolution have predicted either rejection (“that will never work”) or doom (“just you wait, the millennium bug will close us all down”). If we re-enter the time machine, US American engineer Gordon Moore predicted back in 1965 that the number of transistors in an integrated circuit would double every two years—and history has proved him correct. I spoke to a client earlier this week who had just returned from a dental AI conference, and I could hardly get a word in edgeways as he gushed about the many ways AI is driving the dental practice. So, is AI going to revolutionise the way we work and replace people in key moments of a dental patient’s journey? The simple answer is “Hell yes!—and get over it.” I am writing this article myself by the way—no AI in my writing ever, whether it is my daily blog, monthly news- letter or articles for the media—that is just a matter of personal integrity and, frankly, because I enjoy writing. However, I recognise that, when I am advising my clients to embrace the magic of inbound marketing and to create a wealth of online oral health education to position themselves as the expert in their postcode, I am totally

interview | Almost 20 years ago, I saw a lecture by Dr Sascha Jovanovic, and he disrupted my thinking. I hope I can do the same for new generations of dentists and inspire them. My experiences, including traumas, failures and negative influences, have shaped me significantly. I’ve encoun- tered many industry trends not supported by science, and this taught me the importance of adhering to core principles. This is partly why I chose not to expand into a network of clinics; I prefer to maintain control to ensure the highest quality of care for my patients. At the White Clinic, it’s the dedicated people, not the brand, that define our success. Why do you feel the need to share your knowledge and what you feel is important in dentistry? Is this driven by your passion for what you do or is it more than that? Everybody likes to be recognised for what they do, to be valued and appreciated. I gave my first lecture in 2002. Back then, when you got invited to give a lecture, there was no social media. It was an opportunity to talk about science and share an idea, and of course, you felt appre- ciated. I’m a musician at heart, and I have always enjoyed entertaining and feel comfortable in a crowd. I guess public speaking triggered my love for being on stage and entertaining other people. Nowadays, I am so privileged to have this platform, but still every time I finish my presentation, I get off the stage and begin beating myself up about what I’d forgotten to say. I don’t take this privilege for granted, and I put a lot of time and thought into my lectures. In a way, it feels like being a mountain climber in that each summit is a challenge or a surfer for whom every wave is different. Every lecture is unique because the audience is unique and the feedback is unique. It is, to me, an art in itself to keep an audience engaged. By keeping the audience engaged, I hope to inspire them and have a deep impact on the lives of their patients. Therefore, “By keeping the audience engaged, I hope to inspire them and have a deep impact on the lives of their patients.” it is a responsibility I take on with huge accountability and with a strong sense of ethics and principles because of my values. I do it nowadays because if I can inspire just one dentist to do something better, to go back and improve on his or her skills, the way that he or she does things, then the lives of his or her patients will also be affected by that. I think I have had a little bit of an impact in my industry that way, and I am happy about that. Given your expertise and the focus of your exocad Insights lecture on the power of virtual patient repre- sentations—avatars you called them—in dentistry, could you elaborate on how digital tools are transforming the diagnostic and treatment planning processes in dentistry? For younger dentists accustomed to digital tools, the transition might seem straightforward. However, for Gen X and baby boomer dentists raised on analogue techniques—like taking moulds, shipping them off and waiting for the finished dental work—there was often little communication with the lab. This lack of control over the process could lead to significant frustration due to the reliance on external factors that were difficult to manage. Companies like exocad developed this extraordinary tool that allows you to see the future. Everybody knows that AutoCAD is one of the top tools for architectural design. Similarly, exocad is the software for designing teeth. There is an absolute similarity between building a house 23 2 2024

interview | Imagine this happening in dentistry. Of course, patients can’t treat themselves, but what if we gave patients tools to make better-informed decisions? Currently, patients choose dentists based on location, cost, accessibility and recommendations—criteria that lack a scientific basis. Yet, everyone is seeking the best care. I envision a future where patients don’t go to dentists for initial check-ups; instead, they visit scanning centres. There, they will be able to get comprehensive scans, like CBCT, panoramic and facial scanning, integrated with dynamic motion tracking. After the visit, the data will be uploaded to the cloud, where an ethically designed bio- logical treatment plan will be created. The patient will then receive recommendations for a dentist based on clinician experience, technology available to the dentist and user feedback. This approach will revolutionise patient acqui- sition, moving beyond traditional referrals to a system driven by artificial intelligence (AI) feedback. Many lab technicians globally face a common issue: they receive poor-quality scans from dentists, but are expected to work with them regardless, as there’s little hope for improved scans. This situation isn’t ideal, and patients deserve to be aware of this. I foresee a shift driven by patients themselves, revolutionising how they choose their dentists. With advancements in technology and AI, this change is imminent. I am eager to lead this revolution, empowering consumers to make informed decisions about their dental care. “The beauty of the software is that you can monitor each phase, you can do quality checks, and you can communicate and interact [...].” Your work with the Slow Dentistry Global Network emphasises the patient experience and safety during dental visits. How do you see the integration of digital dentistry aligning with the principles of Slow Dentistry and improving the overall patient journey in dental care? People may believe that Slow Dentistry is about working very slowly. It is not. It is about having time in your daily workflow to do things properly. If you are seeing 20–30 patients a day, you will not have time to properly disinfect the room, for example. Taking an intra-oral scan properly can take 15 or 20 minutes, depending on the case, whereas a traditional silicone impression can take 5 minutes, so technically, it is faster to take a silicone impression than an intra-oral scan. It takes, let’s say, 5–8 minutes to take a CBCT scan and 30 minutes to interpret it. A facial scan can take seconds, but it takes you an hour to fuse it in exocad. You must have time in 25 2 2024

interview | medical industry and have doctors prescribe dental treat- ments—because they typically do not. A patient can have cancer, and his or her physician may not know that it might be linked to an oral cyst. I decided to use my platform to get dentistry back into mainstream medicine. That leads to a question I wanted to ask you, relating to your new passion, biological dentistry, and its impact on systemic health. Is it your goal then to reconnect dentistry with medicine? I am so passionate about this, and frustrated at the same time, that I developed an AI-based program called Missing Link. The goal is to use an existing panoramic X-ray, which many people have, to support doctors and patients who are looking for answers and not getting them. We know that most doctors are overwhelmed with work and that healthcare systems are overburdened. Even in rich countries, it is difficult to get a good doctor to spend time with you. What if the missing link in health- care is dentistry? The doctor can scan the patient’s pan- oramic X-ray very quickly using Missing Link to detect any inflammation in the jaw. The patient might not be aware of low-grade inflammation, especially if he or she has no pain, which is not always the first symptom of a problem. Missing Link provides screening and not a diagnosis. So Missing Link is directed at medical doctors not at dentists? Yes, it is aimed at medical doctors. Based on the findings of Missing Link, the doctor will refer the patient to a dentist for proper diagnosis and treatment. In that way, Missing Link will generate a whole new set of patients for the dental community. The dentist too might want to use Missing Link for his or her patients to confirm his or her findings. We developed this platform for the medical community to provide a clear rationale for dental visits. Using AI, it helps doctors demonstrate the necessity of specific diagnostics like CT scans, enhancing patient understand- ing and cooperation. Traditionally, radiologists use similar processes to identify fractures that require surgery. Our tool fills a crucial gap in healthcare communication by facilitating requests for detailed diagnosis and follow-ups between dentists and other medical professionals. How do you manage all you do and stay sane and have a good work–life balance and the time to take good care of yourself? In short, what is a day in the life of Miguel Stanley like? Firstly, I have a very stable family life. Secondly, I have a very limited social life. Thirdly, I have an incredible team of people working with me. I have 48 people at the White Clinic, and we only have seven treatment rooms and do not work on weekends. “Our tool fills a crucial gap in healthcare communication by facilitating requests for detailed diagnosis and follow-ups [...].” I go to events where I can have a huge impact and change people’s lives or at least give them new per- spectives. My day starts at 6:00 a.m. Because I am a surgeon, I do not smoke and I do not drink alcohol. The level of focus I need for my surgeries is like that of a chess player or an athlete. I need to be incredibly focused for a long period. I started fasting about seven years ago. One of the keys to longevity is fasting. We’ve known that since Hippocrates. I never have breakfast and two to three times a week, I only have dinner. This allows the body to go into ketosis and gives you an extraordinary amount of focus and clarity. I use ancient integrative knowledge to keep my body very healthy. I sleep well and monitor my sleep. I treat my job like a religious duty; it is a very sacred thing to me. When I show up to work in the morning, I need to be focused and rested and ready for my commitment to help my patients heal. It is not just a job; it is a mission. The older I get, the more I am committed to having a healthy mind in a healthy body. So, when I go home, my phone is off, and it is family time. I need to really focus on what matters. I can also say, even if people don’t really believe this, that I am where I want to be, it is my luxury to be able to decide this, and I do not try to please anybody. You have previously said that dentistry is one of the most stressful professions. How do you manage stress personally? Managing stress in dentistry requires discipline and a dependable team, which I’m fortunate to have. I don’t handle everything on my own; I rely heavily on my trusted colleagues. We maintain constant communication and share responsibilities. For instance, my orthodontist has been with me for 22 years, and my cosmetic restorative dentist for 18 years. These long-standing relationships contribute to a solid support system. Additionally, by focusing solely on one clinic and selectively accepting only 30–40% of potential patients, I ensure that we never overextend ourselves, and that helps keep our work environment manageable and stress at bay. I only attend about 12 international conferences a year and carefully pick the ones I want to go to. I make sure All images: © Akira Schüttler, exocad 27 2 2024

interview | of and knowledge on advanced dental technologies and their application to holistic dental care, about his approach, findings and experience with AI in dentistry and implantology in particular. The integration of AI in dentistry can have various effects on the dentist–patient relationship. From your perspective, what are the major benefits of using AI in the dental practice in this regard? I had the opportunity to use an AI diagnostic tool with one of my patients yesterday. I asked the patient how it made her feel to see me using AI as an aid in my diagnosis of her health, and she said that she thought it was a good thing as long as I employing my own experience and knowledge to interpret the AI findings. I reassured her that this was the case and that when used with care and expertise AI is becoming an invaluable tool. Actually, the biggest benefit I see is that I am less likely to miss a meaningful finding, and it greatly enhances trust between dentist and patient. Have you been able to further individualise treatment plans since you implemented AI in your office? Our dentists and patients at Lotus Dental Wellness have all experienced the benefits of cutting-edge technology for almost a decade. Each patient already receives very individualised care with every case and treatment. AI only enhances our sensitivity and ability to stay true to a pre- ventive, minimally invasive, accurate diagnostic and treat- ment workflow. Now, if it is not used, patients will ask for it. Some of the data is still anomalous, so it can be over- whelming or hard to explain. Overall, it adds value for me and my patients. Does it save time? How efficient is the use of AI in your office? Yes, it saves time, because it draws out and quantifies findings that may otherwise be unremarkable. In the case of periodontitis and bone loss, I found myself making different treatment recommendations based on seeing measurements of the cemento-enamel junction to the crest visible on routine radiographs. The severity of caries is also now quantified, so decision-making is facilitated, as well as risk assessment. Can AI tools help address dental anxiety among patients? How do patients perceive the trustworthiness of AI-driven diagnostic and treatment recommen- dations? I think the key here is that care, compassion and the goal of improving well-being drive the entire dentist–patient relationship when it is functioning properly. With the aid of AI, trust no longer relies solely on a dentist’s personality or powers of persuasion, both of which are pretty irrelevant to quality of care. Much of what drives patient anxiety is the loss of control or of confidence that what is being done is the right thing. AI helps with that. Robotic surgery conducted by Dr Shepard DeLong and Dr Travis G. Hunt. Let’s dig a bit deeper into the clinical aspects and benefits of AI to your work and your routines in your clinic. We know that you are using a robotic surgery aid. What is it exactly that you have implemented? What are specific challenges in oral surgery utilising a robot? This question strikes close to home. I pour my soul into advancing technology for the dental industry. In almost every way, the quality of care, the beauty of form and the nuts and bolts of strength and function have been enhanced with digital workflows. The ease of operating has increased for our dentists, and our practice has a cult-like following of believers. Good ergonomics and long-term well-being of dentists and other members of the dental team are part of our core values. Robotic surgery for implant placement is the latest addition in our office. m o c . e b o d a . k c o t s – s e y e k n p © i 2 2024 29 © Shepard DeLong

interview | Zeramex/Nobel and Z-SYSTEMS—successfully and fully guided. It was laborious to get all the companies to work together to put the sizes and shapes into the software as fast as possible, and yet we placed a lot of implants while calculating all the data the software didn’t have right yet. Other challenges include carrier systems and implant mounts that are not retentive enough or too retentive for the rigidity and freedom of a robotic arm and incorpo- rated dental handpiece. Also, driver lengths, hand-based carriers and low maximum torque values add to the challenges. How does AI play a role in selecting the most suitable zirconia implant size, shape and placement for each patient? At this point, AI plays a negligible role in implant selection. I know this will come. As talk to text and AI can code, we will move towards an automated, ultra-precise surgical and restorative plan. For now, it is a lot of thought, experience and care that goes into making each case a success. In what ways can AI assist in real-time decision-making during surgery, considering factors like bone density and tissue response? This is where the haptic guidance of the Yomi robot and the freehand feel of the X-Guide allow the surgeon to feel the bone. Visualisation of the surgical site with physical guidance is where Yomi shines. During surgery with X-Guide, the surgeon’s eyes must be on the screen. With Yomi, you get both freehand tactile feel and haptic feedback, and you can use real-time visual ob- servations to modify surgery towards achieving great outcomes. How are ethical concerns addressed, such as patient consent, data security and the responsible use of AI in the context of oral surgery? Have you faced any issues on that? Thank you for asking. Almost all our patients have been very receptive of Yomi. Its use in our practice was pre- ceded by X-Guide and my previous commitment to place ceramic implants exclusively. There is regulatory clearance on all these products and devices, and yet we encounter the unknown and untested when using all of them together. This is where new connections, new workflows and, ultimately, new solutions to human health problems will come from. We have a thorough under- standing of risk and believe privacy, autonomy and informed consent are all paramount in modern medicine. There will be new standards of care. It is up to us to define them. I know that the readers of digital will take what I have said here with a proverbial grain of salt or a bit of healthy caution. I think that is wise. Let experience guide your wisdom and opinion. After you see some- thing intriguing, promising even, follow your own in- tuition and go where it leads. If we utilise new ideas and technology while allowing our human knowledge and hearts to guide what to do, the results are going to build a new reality. This is just the beginning. AI, robotics, ceramic implants—the future we are creating is already here. When we see solutions, I think we must share. I look forward to continuing our conversation and journey!

The Aoralscan 3 scan appeared to be the most photorealistic in comparison. This type of scan texture is characteristic of many IOSs manufactured in China—whether you prefer realistic-looking capture of the intra-oral structures or a more illustrative representation is purely personal preference. Monochromatic scans can also be taken and previewed in scanners’ native software. Scans in monochrome provide a better view of the preparation quality and are even recom- mended to check for any scan issues that are not as obvi- ous when viewed in colour. Monochromatic scans of the same tooth preparation were captured using the five scanners and previewed in their native software. Unlike the native colour rendering, only two notable differences were evident between the five scans (Figs. 4a–e). The iTero Lumina monochromatic scan was bright, almost overexposed, and the edges looked sharply defined. The CEREC Primescan scan had slightly more definition of the occlusal morphology and the mesial and distal margins. Exported scans in third-party software All IOSs have an open architecture that allows scans to be exported and sent to laboratories. These scans are usually exported in three various formats: STL, PLY or OBJ. STL files are exported as monochromatic scans, whereas OBJ and PLY files store colour. Not all IOSs can export OBJ and PLY files, whereas STL files are widely used as a default in the entire industry. This particular set of scanners is capable of exporting scans in these formats: – Aoralscan 3 and Medit i900: STL, PLY and OBJ – TRIOS 5 and iTero Lumina: STL and PLY – CEREC Primescan: STL Table 1: File sizes of the file formats each scanner can export.

opinion | the STL, PLY or OBJ files received and to take a closer look at the detail captured within each scan and the amount of data (Figs. 5a–e). By exporting the scans outside their native software, we can view the scans objectively without the customised colour and opti- mised surface rendering of the individual scanner’s built-in software. Preparation margins can also be reviewed using this software (Figs. 6–10). In the close-up images of the preparation margins and the tessellated mesh (Figs. 11a–e), CEREC Primescan seemed to have had the densest mesh, closely followed by Aoralscan 3 and then the Medit i900, TRIOS 5 and iTero Lumina. There are yet to be any studies investigating the clinical significance of mesh density, and it is important to note that a denser mesh does not necessarily indicate a better scan. 14a When comparing IOSs, we usually compare them to CEREC Primescan, which is commonly regarded as one of the best IOSs in terms of accuracy. It is also a scanner I use daily in the office to fabricate same-day crowns that fit perfectly. In that light, when we compared the preparation margins captured by each IOS (Figs. 12a–e), the iTero Lumina scan also looked quite sharp. The buc- cal and lingual margins were very defined (Figs. 13a–e). Overall, all the scanners did a very good job, especially on the lingual margin, which was supragingival and sharper. The buccal margin, which was closer to the retraction cord, seemed to look less sharp but still acceptable. Keep in mind that iTero Lumina is not currently approved for restorative use by the company—in fact you cannot even choose this in the laboratory form. This option will be released later this year. The company says the scans will be even better once this is released. We will soon find out. Just for interest, iTero Lumina’s scanning technology has a maximum capture distance of 25 mm, whereas CEREC Primescan can measure depth of up to 20 mm. The Medit i900 is around 30 mm. We allocated CEREC Primescan as our reference point when looking for capture deviations to compare against the other scanners (Figs. 14a–c). Based on the coloured deviation key, the meshes of the scans taken with the other scanners were within 50 μm compared with the scan taken with CEREC Primescan. Within the same display mode, we also viewed the aligned scans in a sectional view, which showed minimal differences between the scans. Conclusion 14b 14c Figs. 14a–c: Deviation map of the scans compared with CEREC Primescan’s scan (a; scale of 50 μm) and sectional view (b & c). Very little deviation around the preparation area. may vary slightly based on the combination of the clinician’s scanning technique and the specific scanner used. This variation can influence the final outcome of the dental laboratory technician’s restoration margin. Overall, iTero Lumina and the Medit i900 look promis- ing and add to the long list of capable IOSs on the market right now. Did these perform as well as you thought they would?

“For the patient, the great advantage of guided implant surgery is that it [...] requires fewer surgical and prosthetic 12a sessions [...].” case report | 12b guides the healing of the soft tissue for an optimal aesthetic result.6 The integration of virtual engineering and the digiti- sation of information in dentistry has led to a new par- adigm in dental diagnosis and treatment. Specifically, computer- guided implant surgery was developed to address the limitations of traditional surgical planning, significantly improving the accuracy of implant place- ment.7 Undoubtedly, guided surgery represents a consider- able advance in dentistry and is increasingly used by implant surgeons owing to its many advantages, including excellent predictability. These advantages are illustrated in the following clinical case involving the management of a root fracture of a maxillary central incisor using the current technologies. 13a 13b 14 15a 15b 16a Case summary 16b 17 A 60-year-old male patient had sustained trauma to the maxillary right central incisor (tooth #11), and it showed signs of mobility and pain on mastication (Figs. 1a–d). A periapical radiograph and CBCT scan were taken and root fracture diagnosed. The treatment plan in- volved extraction followed by immediate implant place- ment and loading. Implant planning was performed in exoplan 3.1 Rijeka (exocad; Figs. 2–8), and a surgical guide was designed and 3D-printed from Asiga DentaGUIDE on the MAX UV printer (Asiga; Figs. 9–11). After tooth extraction (Figs. 12a & b), implant surgery was carried out (Figs. 13–17) and a provisional crown was fitted.

case report | 5 6 No abnormalities were found during the extra-oral examination. The patient presented with a low smile line. The intra-oral examination revealed terminal dentition due to generalised periodontal disease. The patient presented with severe resorption of the posterior maxilla bilaterally (Fig. 1). The radiographic examination showed generalised alveolar bone resorption with vertical bone defects (Fig. 2). In accordance with the radiographic and clinical evalua- tion, the patient case was classified as surgically and prosthodontically complex in terms of the International Team for Implantology’s SAC classification (Fig. 3). The SAC classification aids in assessing the degree of difficulty and risk associated with implant-related rehabilitation. Treatment planning Our patient was presented with various treatment plans, encompassing both removable and fixed rehabilitation options. Among these, the patient was informed about the DIGILOG treatment concept. After considering the choices presented, the patient chose to proceed with the DIGILOG option. The DIGILOG concept was developed in collaboration with oral and maxillofacial surgeon Dr Christopher A. Gurries. This approach enables communication between surgeon and prosthodontist with the use of digital technology and analogue surgical treatment, supporting predictable treatment outcomes. Two steps were included in our workflow for immediate full-arch treatment using the DIGILOG concept: the printing of prototypes of the prostheses to assess the peripheral borders, vertical dimension of occlusion, aesthetics, phonetics and occlusion; and the scanning of the intaglio surfaces, peripheral borders and occlusion and transfer of that information to the laboratory to finalise the peripheral borders and vertical dimension of occlusion before milling the monolithic final prostheses. CoDiagnostiX software (Dental Wings) was used for planning the analogue surgical placement of two Straumann zygomatic implants and two Straumann BLX implants in the maxilla and of four Straumann BLX implants in the mandible. The protocol chosen was immediate placement after atraumatic extraction of the remaining teeth while protecting the remaining bone (Figs. 4 & 5). The patient’s STL file was generated and sent to the in-house laboratory to create a 3D-printed model for the surgical planning, allowing us to obtain a surgical model (Fig. 6). 7 To avoid complex procedures for implant placement and to decrease morbidity and costs for the patient, no augmentation was planned. On the same day as implant placement, the milled prostheses would be delivered. Six months later, two digitally fabricated fixed full-arch implant prostheses would be placed. In summary, the treatment workflow was as follows: 1. data acquisition for fabrication of two temporary PMMA prostheses; 2. implant surgery and immediate placement of the temporary prostheses; 3. digital design and manufacture of the final zirconia prostheses; and 4. delivery of the final prostheses and an occlusal splint six months after implant surgery. 8 9 10 41 2 2024

case report | 16 17 Prosthetic procedure The patient was followed up, and at six months after implant placement, an indirect digitisation of the back- poured master cast was done, allowing for superimposi- tion of the tooth position to the implant position (Fig. 11). The final tooth set-up and occlusal scheme were done digitally to ensure optimised aesthetics and function (Fig. 12). Once everything had been digitally verified, the final zirconia prostheses with layered porcelain gingivae were fabricated (Fig. 13). The occlusion was checked, and the patient was given a 3D-printed occlusal splint to protect the implant-supported prostheses, acting as an absorber and distributor of occlusal forces (Fig. 14). A panoramic radiographic was taken to monitor the health around the dental implants at delivery of the prostheses (Fig. 15). The patient was provided with hygiene instructions and scheduled for regular check-ups to ensure ongoing care and monitoring. Treatment outcomes Digital and analogue can be seamlessly integrated to enable a comprehensive assessment and treatment. Optimal planning and meticulous examination play pivotal roles in determining the outcomes of the treatment. A personalised surgical approach is imperative to address the diverse needs and requirements of each individual patient. On the same day as extraction surgery, employing the principle of immediacy and without the necessity of guided bone regeneration, an outstanding functional and aesthetic outcome was accomplished with two Straumann BLX implants and two Straumann zygomatic implants in the maxilla and four Straumann BLX implants in the mandible. Six months later, the patient was very pleased with the retention and aesthetics of the final full- arch implant prostheses. The clinical and radiographic evaluation yielded stable and favourable results, indi- cating positive progress. The prostheses fulfilled the patient’s expectations and needs. She was delighted with the significant change in her smile and in her quality of life (Figs. 16 & 17). Authors’ testimonial The DIGILOG concept, using digital technology to com- plement fundamental surgical and prosthetic principles, along with a scientifically designed armamentarium, allowed for treatment of this case and a predictable outcome.

How to send us your work submission guidelines | m o c . k c o t s r e t t u h S / s l i e x p 2 3 © Please note that all the textual compo- nents of your submission must be com- bined into one MS Word document. Please do not submit multiple files for each of these items: · the complete article; · all the image (tables, charts, photo- graphs, etc.) captions; · the complete list of sources consulted and · the author or contact information (biographical sketch, mailing address, e-mail address, etc.). In addition, images must not be embed- ded into the MS Word document. All im- ages must be submitted separately, and details about such submission follow be- low under image requirements. Text length Article lengths can vary greatly—from 1,500 to 5,500 words—depending on the subject matter. Our approach is that if you need more or fewer words to do the topic justice, then please make the article as long or as short as necessary. We can run an unusually long article in multiple parts, but this usually entails a topic for which each part can stand alone because it contains so much in- formation. In short, we do not want to limit you in terms of article length, so please use the word count above as a general guideline and if you have specific questions, please do not hesitate to contact us. Text formatting We also ask that you forego any special formatting beyond the use of italics and boldface. If you would like to emphasise certain words within the text, please only use italics (do not use underlining or a larger font size). Boldface is reserved for article headers. Please do not use un- derlining. Please use single spacing and make sure that the text is left justified. Please do not centre text on the page. Do not indent paragraphs, rather place a blank line be- tween paragraphs. Please do not add tab stops. Should you require a special layout, please let the word processing pro- gramme you are using help you do this formatting automatically. Similarly, should you need to make a list, or add footnotes or endnotes, please let the word process- ing programme do it for you automatically. There are menus in every programme that will enable you to do so. The fact is that no matter how carefully done, errors can creep in when you try to number footnotes yourself. Any formatting contrary to stated above will require us to remove such formatting before layout, which is very time-consum- ing. Please consider this when formatting your document. Larger image files are always better, and those approximately the size of 1 MB are best. Thus, do not size large image files down to meet our requirements but send us the largest files available. (The larger the starting image is in terms of bytes, the more leeway the designer has for resizing the image in order to fill up more space should there be room available.) Also, please remember that images must not be embedded into the body of the article submitted. Images must be submitted separately to the textual sub- mission. You may submit images via e-mail or share the files in our cloud storage (please contact us for the link). Please also send us a head shot of your- self that is in accordance with the re- quirements stated above so that it can be printed with your article. Image requirements Abstracts Please number images consecutively throughout the article by using a new number for each image. If it is imperative that certain images are grouped together, then use lowercase letters to designate these in a group (for example, 2a, 2b, 2c). Please place image references in your article wherever they are appropriate, whether in the middle or at the end of a sentence. If you do not directly refer to the image, place the reference at the end of the sentence to which it relates enclosed within brackets and before the period. In addition, please note: An abstract of your article is not re- quired. Author or contact information The author’s contact information and a head shot of the author are included at the end of every article. Please note the exact information you would like to ap- pear in this section and format it accord- ing to the requirements stated above. A short biographical sketch may precede the contact information if you provide us with the necessary information (60 words or less). · We require images in TIF or JPEG for- mat. · These images must be no smaller than Questions? 6 x 6 cm in size at 300 DPI. · These image files must be no smaller than 80 KB in size (or they will print the size of a postage stamp!).
