Visitors to EuroPerio10 immerse themselves in joint EFP/Osteology Foundation session Topics included wound healing and soft-tissue management news At EuroPerio10 attendees are being treated to multiple lectures by world-renowned speakers and getting updates on the latest in periodon- tics. On the first day, attendees were also invited to a joint session held by the European Federa- tion of Periodontology (EFP) and Osteology Foundation—and it was well attended. The pri- mary focus was placed on tissue regeneration, wound healing and soft-tissue replacement. “Periodontics is coming back to the lead role in clinical practice”—that was the message from Prof. Phoebus Madianos from the Depart- ment of Periodontics at the National and Kapo- distrian University of Athens in Greece and chair of EuroPerio10, during the press confer- ence yesterday afternoon. Indeed, as Prof. Madi- anos accurately noted, periodontics is “in the heart of the body”, and its crucial role is felt not only in dentistry but also in medicine in general, and taking care of one’s oral health can greatly improve quality of life. Opening the session, Prof. Anton Sculean, chairman of the department of periodontics and the executive director of the School of Dental Medicine at the University of Bern in Switzer- land, gave a brief introduction to the Osteology Foundation and warmly presented the three © Dental Tribune International From left: Profs. Anton Sculean and Sofia Aroca. keynote speakers as well as Prof. Andreas Stav- ropoulos, who is not only the president of the EFP but also a close friend of Prof. Sculean’s. Starting off the discussion, Prof. Sofia Aroca, who is a dentist in France, graciously de- livered her lecture, in which she talked about soft-tissue graft harvesting and the benefits of using collagen matrix and introduced some studies on the topic. Commenting on her pres- entation, she told Dental Tribune International (DTI) that her research team was the first to pro- vide a long-term follow-up of the use of the Geistlich Mucograft collagen matrix. “I was re- ally proud to show the nine-year follow-up of this material and to share with my colleagues the most important factors that they should take into consideration,” she said. The next to present was Prof. Nikolaos Donos, chair of periodontics and implant den- tistry at Queen Mary University of London in the UK, who spoke on wound healing after sur- gical procedures. Dr Giovanni Zucchelli, associ- ate professor of periodontics at the University of Bologna in Italy, then talked about soft-tissue management for aesthetic defects around im- plants. In the coming days, attendees will have the opportunity to participate in a number of lec- ture sessions as well as to attend live mucogin- gival and bone regeneration surgeries, night- mare sessions illustrating worst-case treatment scenarios, video sessions, debates, interviews and symposia. “EuroPerio is a huge meeting to all of us per- iodontists. This is the only place where you can talk clinic, research, science and the future,” Prof. Aroca told DTI. The best EuroPerio ever EFP host press conference at EuroPerio10 On 15 June, prior to the official opening ceremony of EuroPerio10, the European Federation of Periodontology (EFP) invited members of the press to a press conference in order to give them an overview of the congress. For example, the representatives emphasised the high scientific level of the congress programme, which features 41 sessions that are organised on four parallel tracks. For the first time, the main sessions will be recorded and will become available for about three months © European Federation of Periodontology l a n o i t a n r e t n I e n u b i r T l a t n e D © s e g a m i l l A EuroPerio10 presents parallel live surgeries On Thursday morning, Hall D was packed with attendees eagerly awaiting the livestreaming of two mucogingival surgeries that were to be performed to cover multiple gingival recessions. Two of the most widely used approaches were presented: the tunnel technique, which was performed by Dr Ion Zabalegui from Bilbao in Spain, and the coronally advanced flap, performed by Dr Massimo de Sanctis from Vita-Salute San Raffaele University in Milan in Italy. The surgeries ran in parallel and were shown alternately, allowing attendees to follow the critical steps of each method.

Prof. Phoebus Madianos, the chair of EuroPerio10, called the congress, which is the main event for the EFP and the European periodontics community, “the Olympic games of dental congresses”, a title which is justified by the magnitude and impact of the event. He further stressed that periodontics will continue to assume a leading role in clinical practice in dentistry and in medicine in general owing to the growing recognition of its role in systemic dis- eases such as diabetes and cardiovascular disease. In this respect, EFP is committed to improving interdisciplinary communication and collaboration on an institutional level as well as on a practi- tioner level. EuroPerio10, therefore, features a considerable number of interdisciplinary sessions that focus on topics such as cardiology, endocrinology and neurology. Prof. Nicola West, the secretary general of the EFP, highlighted that sustainability has become a key component in the federation’s decision-making process. She also stated that the topic had been key in the organisation of EuroPerio10. She said that this year’s congress will provide about 50 % fewer printed materials compared with EuroPerio9 and that all printed materials are made from re- cycled paper. Among other sustainability measures, free public transport tickets were given to all attendees. 2 17 and 18 June 2022

Neoss celebrates anniversary with NeoScan 1000 Company showcases brand-new intra-oral scanner in Copenhagen © Dental Tribune International © Dental Tribune International news Neoss booth (#C2.18) at EuroPerio10. In commemorating 20 years of its pursuit of treatment simplicity, Swedish implant manufacturer Neoss has pre-launched its new intra-oral scanner, the NeoScan 1000. Dental Tribune International visited the company’s booth (#C2.18) at EuroPerio10 to find out more about the easy-to-use fast-scanning device for a digital workflow. The scanner is both compact and lightweight, causing no dis- comfort for the user, even if it has to be held for a long time. It is user-friendly, allowing the entire process of scanning, optimising and exporting to be done without having to touch the computer. In addition, the NeoScan 1000 is connected to the computer via USB, so no additional power supply is needed. The intra-oral scanner delivers high-resolution and true- colour images, allowing users to distinguish tooth structure and soft tissue so that they can easily identify margin lines and un- dercut areas. On top of this, the scanner comes at an attractive price. It will be fully launched in September in Europe, the US and China. “I’m excited to be here with the Neoss team at EuroPerio10, supporting the dental community, to share and discuss the latest technologies, including our brand-new intra-oral scanner, the NeoScan 1000,” said Dr Robert Gottlander, CEO and president of Neoss Group. Demonstration of NeoScan 1000, Neoss’ new intra-oral scanner. The NeoPro scanner software offers dental professionals fea- tures such as scan history management, smart reminders, margin line tools, inspection and measurement. In combination with the integrated cloud storage offered by NeoConnect, data transfer to and communication with the laboratory can be performed in a seamless and efficient way. ScanPeg with aesthetic healing abutments In order to make scanning even easier, Neoss offers a range of healing abutments into which a dedicated ScanPeg can be in- serted for simplified and accurate single-tooth intra-oral scanning. The push-in ScanPeg is used with the healing abutment and elim- inates the need for a separate scan body. By minimising the ex- change of components, the biological seal is maintained and the tissue level preserved, making the treatment less invasive and more comfortable for patients. According to the company, this unique solution is currently only being offered by Neoss. “Designed with ease of use in mind, the superfast, light- weight NeoScan 1000 fits perfectly in our digital workflow. Com- bined with our aesthetic healing abutment with ScanPeg, it pro- duces high-precision results,” commented Dr Gottlander. He encouraged EuroPerio10 visitors to “stop by the Neoss stand and put our scanner to the test!” Research attacks perceived understanding of dental biofilm establishment and inhibition Studies underline efficacy of essential oil mouthrinse Clinical data released on 16 June at Euro- Perio10 has revealed that Johnson & Johnson’s Listerine essential oil mouthrinse delivers 4.6 times greater interproximal plaque prevention above the gingival margin than does flossing. In a dedicated symposium, three experts presented the findings of two revealing new studies which compared the use of Listerine es- sential oil mouthrinse and brushing with brush- ing and flossing alone for inhibiting the estab- lishment of the dental biofilm. The first study investigated the clinical effi- cacy of supervised mouth rinsing and flossing on plaque over the period of 12 weeks. It was led by research scientist Dr Jeffery L. Milleman, director for clinical operations and principal in- vestigator at US-based clinical research team Salus Research, and provided evidence that rinsing with essential oil mouthrinse is superior to hygienist-conducted and hygienist-super- vised flossing in preventing plaque build-up above the gingival margin. He said: “This study is further evidence that rinsing with an essen- tial oil rinse is an effective adjunct to mechani- cal methods.” Dr Kimberly R. Milleman, director, compli- ance specialist, organoleptic judge and gold standard examiner for Salus Research, pre- sented the second study, which investigated the effects of essential oil mouthwash in oral hy- giene regimens and showed that a regimen of brushing, flossing and rinsing with essential oil mouthrinse provided significant 28.4% greater 6 17 and 18 June 2022 © Dental Tribune International Dr Kimberly R.

She said: “Mouthrinse covers the whole tooth, and when we grade plaque, we are grading it right along the gingival margin and interproxi- mally.” Both studies underline the fact that Lister- ine essential oil mouthrinse—in addition to me- chanical cleaning—delivers more effective oral health. Periodontist Prof. Nicole Arweiler, director and chair of the department of periodontics and peri-implant diseases at the University of Mar- burg’s dental school and hospital in Germany, commented: “Problems start when the dental bi- ofilm becomes established on hard surfaces— the teeth, fillings, or other niches—and starts to develop a life of its own. We know that perio- dontal microflora influence our susceptibility to several diseases, including bacteraemia, endo- carditis, diabetes, autoimmune disease and lung disease. We also find that patients with perio- dontitis have the same markers as for rheuma- toid arthritis.” She continued: “Mechanical hygiene meas- ures to remove the dental biofilm are often in- sufficient. There are many people who do not brush or floss appropriately, plus there are situ- ations when mechanical cleaning is not possi- ble, such as when patients have sutures or fol- lowing new implants. Additionally, there are groups, such as the elderly or people with disa- bilities, who find it difficult to adequately clean using brushing and flossing. An antibacterial mouthrinse can help to kill or ‘defang’ residual biofilms that dental patients have been unable to remove.” Editorial note: For details of the studies and references, please visit www.listerine.eu..

“Periodontics is now the most active specialty” An interview with EuroPerio10 Scientific Chair Prof. David Herrera interview © EFP Prof. David Herrera is the scientific chair of this year’s EuroPerio congress. At EuroPerio10, Dental Tribune International had the opportunity to speak with Prof. David Herrera, who is the scientific chair of this year’s congress. He is a professor of periodontics and the associate dean of dental clinics at the Com- plutense University in Madrid in Spain. He is also the director of the university’s postgradu- ate programme in periodontics, which is accred- ited by the European Federation of Periodontol- ogy (EFP). Prof. Herrera, being scientific chair of Euro- Perio10 sounds like quite a challenge. How has the experience been so far? I have been involved with the EFP for many years. Being the EuroPerio10 scientific chair has been my most important commitment to date. I have been responsible for designing and organ- ising the scientific programme. This is a duty that usually lasts for the three years in between the EuroPerio congresses, but of course, owing to the pandemic and postponing of the con- gress, I have been active with it for the last four years. As the scientific chair, I have had the best time. It is a reward to work with the best prac- titioners in the world. It has been a lot of very challenging work, not an easy job. You must al- ways perform at your best, but at the same time, it is a privilege to get to work with the top ex- perts in the field. When I contacted some of them, I expected that they would not have the time, that they would not be interested in pre- senting a 20-minute lecture. However, this was not the case. They reserve the EuroPerio dates years in advance and wait for the invitation. Even the biggest names do that. We usually do not get negative answers. This year, we have over 130 top-level experts participating. Do you think you are going to miss it? After EuroPerio10, I will wear another hat again as the chair of the EFP Workshop Commit- tee. It is the committee that has been involved in the preparation of the EFP guideline on Stage IV periodontitis. AD EFP has compiled a comprehensive scientific programme with more than 130 speakers for EuroPerio10. Could you please outline the high- lights of this year’s congress? The live surgeries are definitely a high- light. Prof. Giovanni Zucchelli performed the first live surgery at the University of Copenha- gen during the last EuroPerio congress in Am- sterdam in the Netherlands. First, attendees will be able to see and compare two different approaches to treating multiple areas of gingi- val recession. Dr Ion Zabalegui from Bilbao in Spain and Dr Massimo de Sanctis from Milan in Italy will perform the same surgery live, and attendees will be guided through each step. The other live surgery will be performed by Dr Istvan Urban from Budapest in Hun- gary. At EuroPerio10, the EFP guideline on Stage IV periodontitis therapy will be discussed. What are the most significant challenges in this re- spect? Periodontitis in Stage IV is the most severe, most advanced periodontitis. There is bone de- struction of 50 % or more, and the difference be- tween Stage IV and Stage III is that sequelae arise from this. The teeth are moving, or they have moved into a different position. The masti- catory function is not good, and there may be more than five teeth missing, so there are a lot of problems facing a patient in Stage IV perio- dontitis. Even if we can treat the infection and the periodontal tissue is healthy again, the mouth is not functioning properly. Therefore, you need something else. You need periodontal therapy. In this current guideline, we are describing what else you need to do for the patient with Stage IV periodontitis. What do you need to do to restore the masticatory function? You might need orthodontic therapy, prosthodontics or dental implants, whatever you need to do when the periodontal tissue is healthy again to get a stable environment and restore a healthy mouth. SIGN UP NOW Dental Tribune e-newsletter International Newsletter – 16 September 2021 eptember 2021 Europe Newsletter – 2 June 2021 Therefore, it seems essential to have an inter- disciplinary approach with regard to treatment of Stage IV periodontitis. Exactly. It is very important. Orthodontists, prosthodontists and other specialists seem to be very afraid of these cases because they believe the prognosis is going to be poor and that it is not worth investing time and money in those patients. However, based on evidence and what the guideline demonstrates, it is in most cases treatable. You can do something and something much better than removing the teeth and plac- ing implants, because tooth retention has a bet- ter prognosis than the prognosis of an implant. The guideline gives recommendations to periodontists, orthodontists and prosthodon- tists so that they may work successfully to- gether for better treatment results. These most severe cases are usually treated with full extraction, full-mouth dentures and implants. We have shown that this can be avoided. Of course, more advanced analysis and diagnosis are needed in order to be suc- cessful, but it is feasible and worth exploring. At the end, a full-mouth extraction might be needed, but this guideline provides another way to look at a case. How would you describe the current direction of the field of periodontics and the factors that are effecting change? Within the dental specialties, I think that periodontics is now the most active specialty in Europe. From the clinical practice perspective, demand is high because periodontitis is highly prevalent. The ageing population is another fac- tor because periodontitis is encountered more in older populations. Periodontics is also closely connected to what I would call basic science—microbiology, biology, histology—more than the other spe- cialties. I would say that 20% of the scientific publications in dentistry are about periodontics, and 25% of systematic reviews in dentistry are about periodontics. In the end, periodontitis is easily treatable, and the diseases associated with implants are very difficult to treat because the surfaces of the teeth can be cleaned, whereas the implant surface is difficult to treat or decontaminate.

Looking forward to clinical innovations at EuroPerio10 An interview Prof. Giovanni Zucchelli from Italy Meet the expert Prof. Zucchelli, at EuroPerio10, you held a lecture titled “Soft tissue management in esthetic defects around implants—what is the long-term outcome?” during the joint Euro- pean Federation of Periodontology and Osteol- ogy Foundation session on 15 June. What could listeners take away from your presentation? The results are very stable in the long term. More than 80 of the clinical cases I reported on had a follow-up of fi ve to 11 years, and there was not one case with peri-implantitis. We only had two cases of mucositis, and they were com- pletely resolved. All the patients were extremely satisfi ed with the aesthetic outcome. I presented how soft-tissue management around aesthetically failing implants can be integrated in a more complex aesthetic treatment. On 17 June, you will be holding a lecture on coronally advanced fl aps as part of the video session on critical factors in surgical design for periodontal regeneration of infra-bony defects. When and how should a coronally advanced fl ap approach be performed? The coronally advanced fl ap with the ad- junct of connective tissue grafting allows the clinician to treat poor mucogingival conditions associated with intra-bony defects and to im- prove the buccal and interdental (papillary) aes- thetic outcome. Prof. Giovanni Zucchelli is a specialist in periodontics and implantology. It is great! We, as speakers, really need the personal contact, maybe even more than people attending the lectures. What are you personally looking forward to at this year’s EuroPerio? Clinical innovations, because during the confi nement caused by the pandemic, people have had time to think and take further steps in research and development. From your experience as a clinician, what are some of the current trends in periodontics and implant dentistry? How does it feel to be able to teach again in person since the pandemic started? I cannot say anything other than soft-tissue management to improve patient satisfaction.

Periodontitis and peri-implantitis in implant dentistry An interview with Dr Inga Boehncke, member of the German Association of Oral Implantology interview Peri-implantitis continues to be one of the greatest challenges for dental professionals. According to studies, the prevalence of the condition will continue to rise in the coming years. Dental Tribune International spoke with implant specialist Dr Inga Boeh- ncke, who has been running her own practice in Bremen in Ger- many since 2009, about specific features of implant therapy in the case of previous periodontal disease, surgical and non-surgi- cal treatment protocols for peri-implantitis and how the treat- ment of the condition will develop in the future. Dr Boehncke, what is especially challenging about implant treatment for patients with previous periodontal disease? First, a stable periodontal situation must be established by determining and discussing the individual risk profile of the pa- tient. The type and extent of previous periodontal disease play an important role and several questions need to be addressed. Have there been recurrences? Is the periodontal situation stable? Does the patient smoke? Does the patient have diabetes? In addition, it is important to establish and monitor the haemoglobin A1c level, which should normally be determined every three months and should not exceed a value of 6.5 %–7.0 %. Interleukin polymorphisms also need to be considered, espe- cially in combination with several of the aforementioned factors, as about 10 % of patients are high responders, meaning that an inflammatory change can be associated with a stronger to exces- sive reaction. Ultimately, the compliance of patients plays a decisive role regarding the removal of plaque at home and the willingness to undergo oral hygiene at short intervals in order to determine in- dividual biofilm management depending on their risk profile. If periodontal conditions are stable—free of bleeding and with probing depths of no more than 5 mm after previous periodontal disease—we apply a 0.2 % chlorhexidine rinse three times for 30 seconds before implantation. If a film is visible on the tongue, it is removed with a tongue scraper and a chlorhexidine spray is used if necessary. Additionally, periodontally compromised pa- tients are advised to undergo systematic plaque removal in the practice two to three days before the procedure. We also admin- ister vitamin C and vitamin K2 and determine the vitamin D3 level, supplementing depending on the value. During follow-up, we closely monitor, in particular, the ade- quate removal of plaque. Postoperatively, patients are advised to rinse twice daily with a 0.2 % chlorhexidine rinse for 1 minute. Alternatively, a chlorhexidine gel can be applied to the wound area. During subsequent follow-ups, depending on the severity, risk profile and cooperation of the patients, an individual sched- ule of short intervals of monitoring involving biofilm removal and determination of the bleeding on probing is indicated. In addition, we work with the active matrix metalloprotein- ase-8 (aMMP-8) biomarker from Bioscientia, which determines collagenase activity and thus represents a kind of destruction marker. Inflammatory tissue destruction can thus be detected at an early stage before it becomes clinically visible. A value of 0 for the patient is determined two to four weeks after prosthetic restoration of the implant. One year later, another aMMP8 test is carried out. Nowadays, dental implants have a high survival rate, but peri-implant infections are among the most common complica- tions. In the 2019 Delphi study of the European Association for Osseointegration, experts agree that the prevalence of peri-im- plantitis will increase in the coming years. How can dentistry meet this challenge? The prevalence of peri-implant mucositis, which is roughly comparable to gingivitis and is initially limited to the inflamma- tory change in the soft tissue, is currently approximately 43 %. Peri-implantitis, which is associated with inflammatory bone re- sorption that has already occurred, meaning it is comparable to periodontitis, affects approximately 22 % of patients. In my opin- ion, early detection of inflammatory signs and timely intervention are the pillars of postoperative care. Regular bleeding on probing assessment is a key diagnostic tool to detect inflammatory changes at an early stage. As already mentioned, destruction markers can also be used. These are helpful in explaining the therapy to the patient. In addition, patients with implants should be enrolled in spe- cial oral health programmes that include regular systematic re- moval of the microbial biofilm and early inflammatory diagnos- tics. Recent studies have found that mesially and distally splinted implants, as well as implants with an over-contoured restoration, pose an increased risk of peri-implantitis. The more difficult plaque removal for patients and the resulting accumulation of plaque plays a central role in this. The design of the implant superstructure in terms of facilita- tion of cleaning and adequate attachment of the soft tissue should be given high priority from the outset to guarantee pa- tients easy and pain-free plaque removal at home. An unattached and thin mucosa often leads to discomfort during cleaning as well as to faster pocket formation and thus plaque accumulation. We often use Camlog’s NovoMatrix to thicken and secure the peri-im- plant tissue. Peri-implantitis can be treated both surgically and non-sur- gically or with a combination of both methods. However, there is no standardised surgical protocol yet. How can dentists guaran- tee good care for their patients? The decision of whether to treat peri-implantitis surgically or non-surgically depends mainly on the severity and the implant surface. It must be clarified whether a rough surface or even al- ready exposed contaminated threads are present. The first step is to eliminate mechanical risk factors such as overhangs that have contributed to plaque formation. The superstructures should be removed. For both surgical and non-surgical cases, the main focus lies on decontamination. Removal of the microbial bi- ofilm and thus reduction of bacterial colonisation is achieved with hand instruments, ultrasonic tips and powder-blasting de- vices that use glycine powder. In addition, we use multiple 3% hydrogen peroxide rinses and chlorhexidine rinses applied di- rectly and alternately. Local antibiotics can also be administered as a supportive measure. We use Ligosan Slow Release from Kulzer with the aim of keeping the tissue free of bleeding and reducing pocket depths. 1 3 2 4 5 Dr Inga Boehncke. In the case of defect morphologies that limit access or already advanced bone resorption, we apply a surgical therapy that in- volves flap elevation, analogous to open periodontal therapy, to achieve better visibility over the contaminated parts and thus better accessibility. For this purpose, we use fine nickel–titanium brushes for decontamination, as well as glycine powder and re- peated 3 % hydrogen peroxide and chlorhexidine rinses. Furthermore, regenerative work can be carried out, and the success of this is directly related to the morphology of the defect. If a small bowl-shaped intraosseous defect is present, it is easier to regenerate with augmentation than are already developed supra- crestal defects which show screw threads that are above bone level. If this occurs, the threads are removed and the protruding implant surface is smoothed as far as possible to eliminate rough- ness, with the aim of preventing plaque colonisation anew. There are also combined defects for which both procedures can be used. We use autogenous bone chips and a bone substitute material covered with a collagen membrane for regeneration. The main aim is to support the soft tissue, and in many cases thick- ening owing to scarring is observed. How do you think the prevention and treatment of peri-implantitis will develop in the future? Particular attention should be paid to postoperative care at short intervals in order to be able to intervene as early as pos- sible. Immunomodulatory therapies are currently under discus- sion. Through the anti-inflammatory effect of natural cranberry extract on the tissue-destroying macrophages, topical application should directly intervene in the intensity of the inflammatory re- action. Furthermore, I could imagine that new carrier materials for local antibiotics or natural extracts—as already mentioned—will be developed. Modified implant surfaces, possibly with anti-infec- tion or plaque-inhibiting properties, are also conceivable. How- ever, I think it is most important to raise patients’ awareness and motivate them to have regular and thorough follow-up care and to remove plaque at home, irrespective of the therapeutic ap- proach. After all, prevention is better than cure. Fig. 1: Implant site at which soft-tissue enhancement was performed to prevent peri-implantitis.

ACTEON Group, France www.acteongroup.com Booth E13 Osstem-Hiossen Meeting in Europe to take place in autumn AIC Europe, which was founded in 2001 by Osstem Implant, has confi rmed that the Osstem- Hiossen Meeting in Europe 2022 will be held as planned in October in Rome. In addition to a series of lectures to be presented on various topics re- lated to dental implant procedures, the two-day symposium will feature a live surgery, a round- table discussion and an oral competition. The last European symposium in Prague in the Czech Republic gathered dentists from more than 30 countries in Europe, the Middle East, Africa and the US. Owing to the SARS-CoV-2 pandemic, the symposium has had to be suspended for the past two years. This year, the organis- ers are looking for- ward to finally wel- coming participants to a new edition of the symposium, which will be held on 28 and 29 October at the Au- ditorium del Massimo congress centre in the city of Rome. More than 20 re- nowned experts, in- cluding Prof. Bilal al- Nawas from Germany, Dr Darko Božić from Croa- tia, Dr Silvio Meloni and Dr Francesco Mintrone from Italy as well as Waldo Zarco Nosti from Spain, will be speaking about the latest in implant den- tistry. Special guest Dr David Chong from the US will be opening the symposium. The last session on the fi rst day will be de- dicated to a round-table discussion, in which Dr Marco Tallarico from Italy, Dr Hyun-Jun Jung from Korea and Dr Chong will explain different approaches to the maxillary reconstruction of ter- minal dentition. A highlight of the symposium will be the live surgery that will be performed on the second day by Dr Jung and Dr Roberto Scrascia from Italy. Moreover, dentists and dental students will have the opportunity to present their cases in an oral competition or in the poster zone. Abstracts can now be submitted in three categories digital den- tistry, prosthetics and oral surgery. After review by the symposium committee, applicants will be informed whether they will be joining the oral presentation or exhibiting in the poster zone. On Friday night, a gala dinner featuring the fi nest Italian cuisine will offer great networking opportunities in a relaxed atmosphere. Cultural performances will entertain the guests. The whole symposium will be livestreamed through Osstem’s own global broadcasting system, DenAll TV, and other related channels. For more information, please visit www.osstem- europe-meeting.com.

GalvoSurge has been proved to eliminate biofi lm from micro- and macrostruc- tures—even in diffi cult to reach areas, leaving the implant completely clean and prepared for additional therapy, such as bone regenera- tion.1, 2 Peri-implantitis is one of the greatest un- solved problems in dental implantology, and its prevalence is expected to increase as implant treatment becomes more widespread.3 Implant cleaning is a diffi cult but essential step in treat- ing peri-implantitis, and the GalvoSurge im- plant cleaning system offers a new solution for complete decontamination of the implant sur- face independent of the bone defect and is compatible with most implants on the mar- ket.* An easy-to-use system, the process takes 2 minutes per implant and cleans areas that are diffi cult to reach, including threads, under- cuts and microstructures.2 Cleaning methods such as mechanical or instrumental debride- ment can destroy the implant surface and may leave bacteria behind. GalvoSurge has a unique mode of action that breaks away the biofi lm with hydrogen bubbles, leaving the im- plant completely clean and ready for re-osseo- integration (Figs. 1–4).1, 2 This is achieved by spraying an electrolyte solution around the im- plant and passing an extra-low-voltage current through it, producing electrolysis.

The fi rst randomised controlled clinical trial has shown excellent results.1, 4 At six months, all implant sites treated with the GalvoSurge system were free of infl ammation, and com- plete or signifi cant bone fi lling had been achieved around all implants, depending on the bone defect.1 The 18-month results con- fi rmed that the electrolytic cleaning effectively decontaminated the implant surface, allowing the reintegration of the implant into the sur- rounding tissue. Signifi cant radiological gains in bone and reductions in probing pocket depth, bleeding on probing and suppuration were proved and remained stable over the 18-month period.4 In an in vitro study, Galvo- Surge removed oral biofi lm signifi cantly better than other methods of cleaning dental im- plants currently available on the market.2 Fur- thermore, a recently published histological analysis showed that new bone had formed af- ter cleaning with GalvoSurge on an implant surface previously contaminated by biofi lm. These pioneering results demonstrate that re-osseointegration in humans is possible after cleaning with GalvoSurge (Fig. 5).5 Developed and manufactured by the Swiss company GalvoSurge Dental, this dental im- plant cleaning system is distributed exclu- sively by Nobel Biocare.

FIVE WAYS IN WHICH PERIO PLUS REGENERATE PROTECTS YOUR PATIENTS industry More information growth of cells—hence the name “regen- erate”. What is more, the acid protects the regenerating mucosa by creating a protective layer over it. This further sup- ports regeneration, minimising opportu- nities for infection and other complica- tions. Stronger teeth and protection from caries Xylitol not only lends Perio plus regenerate its pleasant taste without spiking blood sugar or insulin, it also helps keep the teeth healthy and pro- tects them from caries. This is because oral bacteria such as Streptococcus mu- tans will ingest xylitol in a similar way to glucose, but cannot use it for fuel. Ingest- ing it leads to further inability to take up glucose, resulting in the bacteria dying. A proper mouthrinse at the proper time can go a long way to- wards protecting your patient’s oral and overall health. Perio plus regenerate is a mouthwash that will help you do just that, in fi ve different ways. Thanks to its composition, Perio plus regenerate has fi ve dis- tinct patient benefi ts: • protection against and elimination of harmful bacteria; • prevention of bad breath; • enhanced mucosa regeneration; • tooth strengthening and protection from dental caries; and • protection of the teeth, gingivae and oral mucosa. Protection against and elimination of harmful bac- teria and prevention of bad breath The two key components of Perio plus regen- erate are chlorhexidine and Citrox. Chlorhexidine digluconate (0.09 %) has been used in dentistry for over 70 years and is very effi cient in eliminating harmful bacteria, a factor which is critical, especially after sur- gery and other procedures. Citrox is a much newer ingredient based on natural biofl avonoids. Derived from bitter oranges, it is very effective against bacteria, viruses and fungi alike. In Perio plus regenerate, Citrox is fur- ther combined with polylysine amino ac- ids to create the Citrox/P formula. As a result, it creates a protective layer on the teeth, gingivae and oral mucosa. Teeth, gingivae and oral mucosa protection • as additional short-term infection protection during epidem- Perio plus regenerate is unique in the combined action of several of its ingredients: hyaluronic acid combines with poly- mers to create a protective layer, while chlorhexidine binds to the mucosa and teeth, helping fi ght bacteria. All of this helps to keep the mucosa protected, reducing the risk of viral or bacte- rial infection. ics. How to use Perio plus regenerate: • Rinse with 10 ml undiluted for 60 seconds. • Use morning and night, for up to one month. • Rinse with 10 ml undiluted for 60 seconds. • Use morning and night, for up to one month.
