METHOD FOR DESIGNING A TOOTH REPLACEMENT PART, METHOD FOR WORKING A DESIGNED TOOTH REPLACEMENT PART, TOOTH REPLACEMENT PART, AND COMPUTER-READABLE MEDIUM

摘要

The invention relates to a method for designing a tooth replacement part, which is intended to be able to be mounted on a residual tooth area and in which a spacer (1) is provided between the tooth replacement part (2) and the residual tooth area (3), and the subsequent step of testing whether one or more undercuts (4) are present in the tooth replacement part. The invention further relates to a method for working a designed tooth replacement part with one or more undercuts present, wherein a spacer is provided between the tooth replacement part and a residual tooth area and wherein a form of the spacer is modified in order to remove the undercut or undercuts of the tooth replacement part. The invention also relates to a method in which the formation of undercuts is avoided by provision or modification of a spacer. The invention moreover relates to a tooth replacement part provided with a spacer, wherein the spacer of the tooth replacement part has first and second spacer areas and between these a transition area, with no undercut present in the transition area. The invention also relates to a corresponding computer-readable medium.
