Digital dentistry has developed rapidly in recent years and there have always been different questions concerning this computer-based field. A long time ago, the first question was whether one may use metal ceramics or full ceramics. The question has already been answered as full ceramic restorations can be used today, with a few exceptions. Then the question of working full digitally or rather conventionally emerged, especially in the field of impression taking. Today intraoral scanners are so far developed that they can cover a larger area of dentistry. At the moment the question arises whether teeth still need to be prepped to improve the hold of the crown, or can new developed cement provide this hold. In this poster I will present you different cases in which we have used different techniques and different materials in order to answer to this question.
Case 01 A patient with a TMJ arthrosis presented herself in our clinic and asked for a complete new treatment of the upper and lower jaw. The occlusion and interocclusal distance must therefore be optimized. This may requires extensive prosthetic proceedings, such as bite elevation using an adjusted splint and complete prosthetic rehabilitation. A bite splint was performed conventionally using normal a physical impression and Kavo articulator to raise the bite. After six month the patient was scanned with intraoral scanner and the works were made of different materials. Lithiumdisilicate monolithic was used in the lower jaw’s front and the front of the upper jaw was made of buccal veneered zirconium. The patient was then very satisfied.
Case 02 A patient with a deep bite presented herself in our clinic with the desire to optimize the overall bite and aesthetics. In the first step we decided to treat the patient fully digitally without taking a physical impression. The patient received an aesthetic milled splint, with which we raised the bite by 4 mm. She was satisfied with the splint and liked to wear it, what made our therapy relatively easy. The splint was then followed by a highly esthetic temporary made of hybrid composite in natural colors, of which she was very enthusiastic about. We then prepared minimally and used different materials according to the indications. We used monolithic zirconium in the posterior regions.
Case 03 Our third patient with a lips palate column with missed tooth in the front; he did not want an implant, because it would make several operations unavoidable. We opted for the non-prep and fully digital workflow for this patient in order to be able to quickly treat the patient within two sessions. We have preferred for all-ceramic cantilever resin-bonded fixed dental prostheses here.
The current digital dentistry technology allows with its variety a range of minimally invasive care, and replaces the conventional technology in many areas.
