On the fourth lecture of the online spring semester of 2021 dr. Péter Hermann (Vice-Rector for Educational Affairs, Head of the Department of Prosthodontics, professor) held a presentation about the latest digital technology of dental fittings. During the lecture he presented the operation of the intraoral scanner and showed how modern methods have changed the work of dentists.
Dr. Péter Hermann pointed out that it is inevitable that digital technology will replace analogue methods in the field of dentistry and dental fittings. In his presentation titled “Increased use of digital technology during making of dental fittings” dr. Hermann (Vice-Rector for Educational Effairs, Director and Professor of the Department of Prosthodontics) showed the traditional way of making dental fittings and how the latest technology has changed this process over the years. In the past we took analogue impressions of the jawbone (which is a negative imprint). Then gypsum was poured in this to produce a dental replica. Later on a wax pattern of the dental fittings were put on the replica. This was followed by another pouring, resulting in a metal frame which was later concealed by using ceramics. The vice rector added that modern dental impressions can be made in a digital way -using an intraoral scanner. The data is then transferred to computers in the laboratory, where a special machine makes dental crowns using milling. Before applying the dental fitting, the final step requires manual precision.
In the past few years a question has been raised among dental technicians: Will their work be needed in the future or machines will take over the industry. Actually, there is no reason to be afraid, Steve Jobs once said: Technology alone is not enough, someone needs to make the system work.
Dr. Péter Hermann also added that earlier dental technicians had to learn the technique of dental casting, nowadays they have to acquire other sorts of knowledge concerning dental fittings. The Department of Prosthodontics is striving to help dentists: 13 intraoral scanners have been tested between 2019 and 2021, giving a guidance to colleagues on how to choose the most suitable machine. The vice rector drew special attention to the fact that digital technology is much safer during the current epidemiological situation, as large part of the information is transmitted online, it requires less physical contact than the traditional, analogue methods.
Dr. Péter Hermann introduced the tools and materials used in new dental fitting procedures. He also mentioned 3D printers: printed materials are not precise enough, as they have different physical features and colours than the traditionally made materials. Therefore they can not be used as the final product of dental fitting. However, this technique can be applied for producing temporary dental fittings and it can replace gypsum to produce dental patterns.
The use of digital technology has become more common in the field of implantology- said the vice rector. He also added that thanks to the study of dental materials and technological development, materials can be used for more different purposes than before. Zirconium dioxide was used before as a substitute for the steel frame, however nowadays due to developed milling techniques the whole occlusal surface and the crown can be made of it. Dr. Péter Hermann also pointed out that doctors should choose the most advantageous and least invasive dental fitting procedure for each patient.
He mentioned the importance of choosing the right tooth color. Take a brilliant the dentist and a dental technician, who makes the dental fitting according to his best knowledge. If the color doesn’t comply with the patient and the dental fitting’s surrounding, we can be sure that the patient will not be satisfied. This emphasizes the subjectivity of colour vision and perception.
Digital dentistry requires the knowledge of different areas (such as computer science, physics, mathematics) that are not closely related to dentistry. The next generation of dental fitting professionals will have to acquire these, said dr. Péter Hermann adding that Semmelweis University and Neumann János University plan to start a B.Sc. programme in Digital dental planning. Students will be able to acquire the basics of these areas during the course.
At the conclusion of the presentation the vice rector illustrated dental fitting methods and techniques using practical examples, which had been previously mentioned in his presentation.
