SHOW REVIEW 40th International Dental Show • Cologne • 14–18 March 2023 Impressions Over the course of fi ve days, IDS offered visitors the opportunity to see and try out the most current innovations in dentistry. Aesthetic solutions Products in focus Austrian manufacturer edelweiss dentistry pre- sented its newest development: the edelweiss CAD/CAM BLOCK at its booth. Complete digital workfl ows, sustainability and artifi cial intelligence applications were some of the trends observed at this year’s event. » 4 » 6 » 11 IDS celebrates great comeback Thousands attend centenary of the world’s leading dental show. nIDS, which celebrated its 100th anniversary this year, was held from 14 to 18 March. According to organiser Koelnmesse, around 120,000 visitors from 162 countries attended, 60% from abroad. Like usual, attendance by EU countries, particularly It- aly, France, the Netherlands, Spain, Belgium, Romania and Greece, was high. In addition, there were many visitors from Asia, South America, the US and Canada. In total, 1,788 compa- nies from 60 countries exhibited at the show. These included 433 exhibitors from Germany. A visitor survey showed that visitors’ overall assessment of IDS 2023 was positive. Over 80% were very satisfi ed with the event, 83% praised the comprehensive showcase and almost 90% would recommend visiting IDS to their business partners. Furthermore, 84% of the respondents were satisfi ed with the IDSconnect digital platform and its additional off ers. Mark Stephen Pace, chairman of the board of directors of the Association of the German Dental Industry, commented: “IDS 2023 was a success across the board, and at the same time, it proved that even after 100 years it is still reinventing itself and developing further. IDS has once again confi rmed that it is a world-leading trade fair. The quality of the visitors was sensa- tional. Together with Koelnmesse, we will successfully lead IDS into the second century of the event’s history with energy, am- bition, creativity and vision. This year’s slogan of ‘100 years of IDS—shaping the dental future’ refl ects the outstanding impor- tance of the trade fair today and in the future.” Chief Operating Offi cer of Koelnmesse Oliver Frese added: “Over fi ve days, we experienced an IDS that more than lived up to its claim as a leading international hub. This gives the global dental industry the necessary impetus for the coming months and, at the same time, underlines the global appeal that ema- nates from IDS. The result of the event is all the more remark- able as the geopolitical framework conditions are currently a challenge.” The overall feedback from the exhibitors was very positive too. Fred Freedman, vice president of member services at the Dental Trade Alliance and president of International Dental Manufacturers, stated: “IDS is the largest and best international dental meeting in the world. The 2023 IDS can be summed up in one sound bite: IDS is back. With the enormous crowds and thousands of international distributors and visitors, this is a must for all US manufacturers and companies looking for new international business.” Simon Campion, president and CEO of Dentsply Sirona, con- cluded: “It was important for us as a company to be back on-site and meet our customers in person because that makes a diff er- ence. Under the motto ‘United for better dentistry’, we off ered our visitors a programme with 40 hours of live demonstrations and hands-on training. In addition, we made clear statements on the topics of digitalisation and sustainability with our panel dis- cussions. We can positively impact the lives of millions of pa- tients. We can only do this through mutual exchange and closer collaboration.” In an interview with Dental Tribune International, Stanley Bergman, CEO and chairman of the board of Henry Schein, men- tioned that “one of the highlights in attending IDS is the oppor- tunity to tour the exhibit hall, preview the vast array of new technologies and products being showcased and meet with many of our Team Schein members representing our busi- nesses across the Europe, Middle East and Africa region. At- tending IDS also provides an opportunity to meet with our supplier partners and to speak with our customers—dentists and other dental professionals—and together discover the lat- est innovations and advancements in the fi eld”. He continued: “Many of these products and technologies are designed to make dental procedures easier and more effi cient, leading to better patient care and satisfaction. This includes easy-to-use clinical digital workfl ow solutions fostering open ar- chitecture and product interoperability, advancements in 3D printing and resources to enhance workfl ow management, sys- tems and product integration. That’s why it is so motivating to experience fi rst-hand the reaction of dental practitioners to our company’s rich line-up of activities promoting technology ad- vances in dentistry, a wide range of value-added services and educational insights from industry and professional thought leaders.” Trends in 2023 and beyond Two topics stood out at this year’s IDS: completely digital workfl ows and sustainability. Furthermore, a considerable num- ber of companies showcased artifi cial intelligence (AI) appli- cations. Straumann, for example, introduced a new software solu- tion for its Virtuo Vivo intra-oral scanner which will improve the speed and accuracy of digital impression taking. Intra-oral scans are the entry point for digital workfl ows and will be au- tomatically connected to the Straumann AXS platform and var- ious services in the future. Following its recently established partnership with Smilecloud, Straumann launched its smile design and centralised collabo- ration platform developed by dentists for dental professionals in selected European markets. Smilecloud allows clinicians to design virtual mock-up smiles for patients. Straumann also launched its fi rst dynamic surgical naviga- tion system to perform implant treatment in a fully digital work- fl ow. Straumann Falcon will be available in select European countries. ClearCorrect launched an array of new innovations to help dentists treat complex cases. Included in the launch were im- provements to ClearCorrect’s aligner via an enhanced end-to- end workfl ow that allows dentists to effi ciently treat patients who have missing or erupting teeth with pontics, bars and guides. In addition, ClearCorrect launched the ClearCorrect

opinion Artifi cial intelligence: A gift to dentists Dr Kyle Stanley explains the benefi ts of artifi cial intelligence technology in dentistry. 9 m m o o c c . . k k c c o o t t s s r r e e t t t t u u h h S S / / 8 8 4 4 1 1 s s v v © © nThe May 2019 edition of The Atlantic magazine contained an arti- cle titled “The truth about dentistry”. In it, the author visualised dentists— not a particular dentist but dentists in the abstract—as sinister authority fi gures looming over the helpless patient’s recumbent form, drill in hand. Mistrust permeated the scene like swamp fog. “When he points at spectral smudges on an X-ray,” the author pleads, “how are we to know what’s true?” Then there was the Dustin Hoff - man movie Marathon Man with its Nazi dentist-cum-torturer, and the famous—or, if you’re a dentist, noto- rious—1997 Reader’s Digest article by a writer who visited 50 dentists in 28 states, picking them at random out of the Yellow Pages, and was given treatment plans ranging in cost from under US$500 to nearly US$30,000. That one really hit a nerve, so to speak. Dentists have had their share of bad rap, but still, the experience of the Reader’s Digest writer was pro- bably not terribly far from the truth. It was borne out, with eerie accu- racy, by a 2021 Dental AI Council study intended to quantify the sus- pected inconsistencies in dental diag- nosis and treatment. The same set of full-mouth radiographs was pre- sented to 136 dentists, and they were asked to provide tooth-by-tooth diag- noses and a treatment plan. A per- son with confi dence in the scientifi c basis of dentistry might naturally ex- pect a limited amount of diversity among the responses and would as- sume that the commonalities would far outweigh the diff erences. Not so. Not once did more than half of the participants agree about the diagno- sis for a given tooth. The variety of estimated costs was almost comical, ranging from US$300 to US$36,000— fi gures strikingly similar to those cited by the Reader’s Digest author. Worse, the range of cost estimates did not present as a bell curve, the majority of responses clustered to- gether and only a few outliers at the extremes. Instead, the distribution was more or less fl at; the frequency of a cost estimate of US$1,000 was about the same as that of a cost esti- mate of US$10,000. Other studies have found that den- tists’ interpretation of radiographs— the very foundation of diagnosis— was far from reliable. Estimates of cavity depth and recognition of radi- olucencies were wrong as often as they were right. In another study, three dentists examined several thou- sand radiographs; their interpreta- tions were in full agreement only 4% of the time. Houston, we have a problem How should we account for this lack of precision in a medical fi eld? Is it due to dishonesty? To greed? To variations in skill? To honest diff er- ences of opinion? Whatever the rea- son, it gives dentistry a bad name. But there is a remedy. It comes in the form of a powerful new technology that is already transforming many aspects of our lives: artifi cial intelli- gence, or AI for short. AI is an umbrella term covering a wide range of computing techniques. They range from “general AI”—intelli- gence indistinguishable from that of a human being, in all circumstances— to “narrow AI”, specialised programs whose expertise is limited to a par- ticular class of problem. Most make use of a programming technique called a “neural network” by loose analogy to the structure of the hu- man brain, and all have in common the property of trainability. They learn by taking in vast amounts of data of a certain type—say, photographs of faces or samples of text—and extract- ing commonalities. Once trained, an AI program can pick out a particular face in a crowd or write an essay or a love poem as well as or better than you can. General AI is the darling of sci- ence fi ction writers, but is very far from realisation. No AI system has anything like the broad knowledge of all aspects of the world that a hu- man being has, and so, for the time being at least, we do not have to worry about being taken over by in- dependent-minded and malevolent ro- bots like the notorious HAL of 2001: A Space Odyssey. Even the compara- tively limited task of safely operating a car in an urban environment has not yet been mastered, despite years of eff ort and oceans of investment. Narrow AIs, however, already easily match or surpass human abili- ties, and they have become the tools of choice for performing many exact- ing tasks. Many of these involve com- puter vision, the analysis and recog- nition of objects or imagery. More than a decade ago, it was found that a trained AI could recognise and cat- egorise nodules in radiographs of cancer patients’ lungs as accurately as a panel of oncologists could, and much faster. Computer vision and AI are now familiar parts of the oncolog- ical toolkit, and they are being ap- plied to a widening array of medical fi elds. One of those is dentistry. Dentists are in an excellent posi- tion to take full advantage of AI. There exists, to start with, a virtu- ally limitless supply of dental radio- graphs for training. The radiographic image is the coin of the realm in den- tistry; patients are accustomed to having their pathologies explained to them with reference to the “spectral smudges on an X-ray” evoked by The Atlantic’s reporter. The range of pathologies to be detected is rela- tively narrow, and the AI program can not only identify them but also quantify them with greater than hu- man precision. The dental radiograph is, therefore, an ideal application for the sharp focus of narrow AI. The second opinion—so to speak— provided by an AI program is directly valuable to the practitioner. The com- puter is hypersensitive to subtle grey- scale gradations; it may detect some- thing the human reader has over- looked. More importantly, it is never tired, distracted or rushed and so is not prone to the types of mistakes and oversights that people routinely make simply because they are hu- man. The AI program may in many cases simply duplicate the percep- tions of the human, in which case nothing is gained but confi rmation, but it may add information over- looked by the human or diff er in its interpretation, leading to a re-exami- nation and re-evaluation of the evi- dence. Even if these benefi ts may seem minor to an experienced practitioner confi dent in his or her abilities, there is another side of the AI experience to consider: the patient’s. The results of the AI program’s analysis are pre- sented to the patient in vivid, intui- tively understandable form. The radi- ograph no longer consists merely of spectral smudges, but has become graphically compelling, having high- lighted areas, colour-coded outlines and explanatory labels. For a patient, the enhanced display conveys a heightened sense of precision, clarity and objectivity. The diagnosis is no longer just the opinion of one person, whom a cynic might suspect of ulte- rior motives. It need not be taken on faith; it is supported by the unbiased authority of a digital computer. While the graphic presentation of a computed analysis may impress a patient as something more than human, the practitioner should be aware that the AI program is an assis- tant, not a supervisor. Even though the accuracy of AI’s radiographic analyses in various medical fi elds has been shown to be indistinguisha- ble from that of human interpreters, the AI program actually knows much less about teeth (or lungs or livers) than the trained and experienced practitioner does. What it does know, and knows very well, is how a large number of specialists have inter- preted a very large number of radio- graphs. Its fi ndings are, in eff ect, those that hundreds or thousands of dentists would make if they were to vote on the content of a given radio- graph. Where there is not unanimous agreement, majority opinion prevails, or fi ndings are presented in terms of probabilities. The practitioner using the AI program remains entirely free to form a diff erent opinion or to disre- gard the advice the program gives, but has the benefi t of knowing what a large group of peers would have made of the radiograph in question. The most signifi cant impact of dental AI, however, is not that it nec- essarily brings a superhuman level of certainty to the data upon which diagnoses are based—although in most cases it may—but that it provides, for the fi rst time, an objective and uni- versally accessible standard of refer- ence. Objective standards are pre- cisely the thing that dentistry has lacked in the past, and their absence has given rise to suspicions about the candour and consistency of den- tal diagnoses. Look at the Reader’s Digest writer: guided only by a phone book, he collected a bewilderingly large variety of diagnoses. If he had visited only dental offi ces using an AI assistant, he would have been given a much smaller variety, and the dif- ferences would have been due to small variations among the radio- graphs made by diff erent practices rather than to the whims of individ- ual dentists or the immediate fi nan- cial needs besetting them. Consistency is not the only thing AI brings to dentistry. It also provides support for insurance claims and fa- cilitates record-keeping, tracking of patients’ dental health and compari- son of performance among multiple practices in an organisation. It trains dentists at the same time as dentists train it. In the future, it may reveal connections between dental health and general health that we do not now suspect. Those are some of the collateral benefi ts. Above all, however, AI will give patients the reassurance of knowing that the condition of their teeth is not merely a matter of opin- ion. 7 Editorial note: This article was published in digital—international magazine of digital dentis- try vol. 4, issue 1/2023.

Utilising a digital pro- cess ensures that your crown or im- plant will have a better fit. Digital solutions enable improved patient communication every step of the way. It also ensures a safer workflow; you can do scans every day, two or three times per day, with zero risk to clini- cian or patient. A clinician can also keep far better track of the success and status of patient treatment from one visit to the next. With our scan- ner, you can easily check the dif- ferences between scans taken six months ago and scans taken today. Monitoring progress is very impor- tant for longer-term therapy. Using a digital solution helps keep the dis- cussion with your patients open. Zenere: With our scanner we have something that is called the quality map so dentists can check the quality of an impression before they send it to the laboratory. Our quality map has three easy colour schemes: green indicates that you have enough information, red indicates you do not have enough information and yellow means you are in between. With one click, you can literally see whether you have scanned in enough infor- mation or whether you just need to scan a little more around the area of interest. You don’t need to have everything green; you can focus on a particular area of interest or, if it is an orthodontic issue, you can scan the whole arch. Do you have anything else you would like to share with our readers about 3DISC? Pochon: Our first priority at 3DISC is to provide products that are just simple. This is key for those den- tists who do not view themselves as tech-savvy. When the technology is really mature, the technology becomes simple. It is much more about bring- ing to the dentist something which is sufficiently simple and ready to be used widely. 7  Marie-Laure Pochon is the CEO and president of 3DISC.  Luigi Zenere is 3DISC’s commercial director for Europe. customer service, sales and technical departments. We combine this feed- back with information from other departments and hold regular discus- sions with the research and develop- ment team.

When a patient presents at the den- tal clinic with one problem, often the clinician will note other existing is- sues. We want to help the clinician explain the other issues better so that the patient can easily under- stand what is going on with his or her mouth.

At the show, Dental Tribune International spoke with CEO and president of 3DISC Marie-Laure Pochon and Luigi Zenere, the company’s commercial director for Europe, about a new intra-oral scanner and about the value of tran- sitioning to a digital workflow. Ms Pochon, you have a very robust background in both business and engineering. How does this influence your role at 3DISC? Pochon: As the CEO of 3DISC, I focus my energy on three things: The first and foremost is research and development, which drives the fu- ture of our company and the develop- ment of new products. My role in- volves considering what we need to put on the market in order to take us further. My second focus is on ensur- ing that our customers are satisfied, and my third goal, which is just as important, is to drive the commercial team. Speaking to the development of new products, what goes into the deci- sion-making process when a global company like 3DISC decides to up- date a product or programme? Pochon: We have a product com- mittee that listens very closely to the voices of our customers through our “Using a digital solution helps keep the discussion with your patients open.” Marie-Laure Pochon, 3DISC CEO Pochon: During IDS, we launched a second scanner called OVO, which combines three technologies into one product: a scanner, a 2D camera and dedicated software that enables com- munication with the patient. In fact, what we want is that dentists don’t just use this scanner to send appliances to the laboratories but also use it as a clinical tool with their patients. We want the patient to have an improved understanding of what the clinician practitioner can document the 2D and 3D scans, along with comments, an optional smile design and all moni- toring data in one app on the iPad. This can then be put in the hands of the patient, and the patient can liter- ally play with their own 3D render- ing. If the clinician chooses to use the smile design feature, then the patient will be able to see the design pictures and have a clear idea of the proposed outcome of the planned procedure.  3DISC has named their latest scanner OVO so that its name is easily understood across many languages. OVO indicates both its shape and the positive meaning “to shout for joy” in Latin. 40th International Dental Show 2023 SHOW REVIEW
