ARTIFICIAL TOOTH AND METHOD FOR PRODUCING A DENTURE BASE

摘要

Artificial teeth are inserted into a denture base for producing a denture. The artificial teeth have an outer part, which is visible in the inserted state. An inner part is arranged within the denture base in the inserted state. A tooth edge with a change of angle is embodied between the outer part and the inner part. For producing a denture base, cavities are generated in the denture base. In order to be able to produce the cavities with the aid of automated production methods such as CAD/CAM methods, there is a virtual subtraction of the artificial teeth from a virtual denture base. As a result of this, a cavity edge which corresponds to the tooth edge is generated. The cavity edge is used during the production of the cavity by a CAD/CAM method for setting the tool movement.

1. Artificial tooth for insertion into a denture base, comprising
an outer part visible in the inserted state, and an inner part arranged in the denture base when in the inserted state, wherein a tooth edge with a change of angle is formed between the outer part and the inner part and the inner part is free of undercuts with respect to a direction of insertion in which the tooth is inserted into the denture base.
