Cyfrowe protezy całkowite. Pierwsze kliniczne i techniczne doświadczenie z Digital Denture System (Wieland Dental)
The patient was asked to carefully close against the opposing jaw. After that, the UTS CAD appliance was used to check the parallelism of the occlusal plane to the bipupillary line and Camper’s plane.
To determine the maxillomandibular relations, a Gnathometer CAD was used. This appliance is designed for taking needle point tracing records in edentulous patients. The bite rim supports were removed and the Gnathometer CAD mounted. Colouring material (crayon, felt tip pen) was applied to the lower registration plate and the patient was asked to perform retrusive, protrusive and lateral movements. The coloured registration plate showed the typical gothic arch tracing record produced by the tracing stylus. The perforation of the fixing plate was aligned with the arrow head of the arch (centric relation) and secured in position.
The patient was asked to occlude. This allowed us to check if the centric relation was established correctly (Fig. 9). The three-dimensional maxillomandibular record can be immobilized with a suitable material (e.g. CADBite). Lastly, the patient’s esthetic lines (midline, canine- to-canine line, smile line, lip closure line) were marked on the record. The immobilized record was then forwarded to the lab, together with information about the tooth selection and CP and BP values.

Both sides of the record can be digitized in their exact position thanks to the denture [...]
