Learning exciting new technologies in digital dentistry

Course experience - Fundamentals of CAD/CAM
by Dr. Anas Salim

My course experience at the Nordic Institute of Dental Education (NIDE) was very interesting, especially for me as a dentist and PhD student. Most of the dentists are motivated to learn and improve their theoretical and clinical knowledge, and to understand and pursuit the innovations in the changing world. It is necessary, for example, for the clinicians to be involved and learn about innovations and technologies in digital dentistry, how to adapt them to benefit their patients. Therefore, I was excited to learn about new technologies and innovations produced toward enhancing the quality of dental care and perfection of dental treatment, as well as overall satisfaction of patients.

The staff was very helpful and replied to all our questions. During the course, we were able to understand the terminology and methods regarding the CAD/CAM techniques. The term CAD/CAM technology itself is the abbreviation of Computer-Aided Design and Computer-Aided Manufacturing, respectively. Simply, it means that “digital technologies” and “dental treatment” are incorporated together in one term “digital dentistry”, toward performing the best possible dental care.

The content of the course was sufficient to general dentists and specialised dentists who need to go through the CAD/CAM procedure starting from the beginning. Moreover, the course successfully addressed the CAD/CAM process from the chairside step until cementation of a crown inside patient’s mouth. At the end of the course, we were able to make more than two restorations.

The course and other side-program activities were properly planned. The content of the course was also sufficient for all of us with little knowledge in CAD/CAM systems. It is an excellent choice for prosthodontists and general dentists interested to improve their knowledge in this technology. The first part of it (theoretical part) of the course was enough to cover the scientific basics of the CAD/CAM system. The theoretical part successfully addressed several topics.  For example: the history of CAD/CAM system, indications of using it, limitations, preparation concepts, types of materials, criteria of materials selection, protocols of adhesion to tooth structure, cementation procedures, many clinical cases, and some clinical tips to ensure the accuracy of work and proper scientific ways to deal with different clinical emergency scenarios.

The second part of the course was more practically oriented. It also addressed several practical topics needed during the clinical restorative procedure itself. Starting from the registration of intraoral structures in three-dimensional mode (occlusal surfaces, buccal and lingual side, other intraoral anatomies), using a professional and high-accurate intraoral optical scanners. After obtaining a clear registration of intraoral structures, the second step was designing the crown on the prepared tooth in 3-D model, using a well-designed software (Planmeca Romexis).  After including all the required details of the desired final restoration (length, width, type of material, and other details), we sent the final design to milling machines. After cutting the prepared crown and checking occlusion, we were trained to stain and glaze the restorations. The final shape of the restoration was very accurate. It was a very fast procedure. In less than 30 minutes, we were able to scan, design, and send the desired crown to mill, which again took only 8-15 minutes to prepare the crown!

It is also important to mention the remarkable and unforgettable visit to the Planmeca’s seaside villa. We spent a really nice time together at the harbour seaside. We also enjoyed the place and a nice Nordic dinner which reflects the Finnish culture.

Finally, when someone hears about Finland, the first thing to come to his or her mind is the best quality. Since Finland has been ranked as number one in education, life quality, health treatment, etc., NIDE as an educational institute is combining more than one of these characteristics, it is am educational institute located in Finland. Therefore, I am highly recommending the courses of NIDE to all the general and specialised dentists and clinicians interested to learn and improve their scientific knowledge in dentistry.
