The Biofunctional Prosthetic System provides a solution to this problem: it comprises the intraoral registration device Gnathometer M. Gnathometer M is prepared for needle point tracing based on a closed-mouth impression. This was also done in the present case. First, the device was correctly positioned in the mouth by means of a mounting jig. Then the needle point tracing record was made (Figs 7 and 8).
Suitable denture teeth were selected during the same appointment. We generally believe that it is very important to involve the patient in the selection process. Information about the patient’s satisfaction with previous tooth moulds, shades and tooth positions is also very helpful. In addition, a form selector was used (Phonares II FormSelector), which assisted in determining the suitable tooth moulds based on the patient’s interalar width. The Phonares denture tooth line allows teeth to be selected that are matched to the individual characteristics of the patient. Even though these teeth are „prefabricated”, they do not look like they are ready-made. Thus dentures result [...]
