A digital design method for the shape of a bionic dental crown with individual functions

Abstract

The invention relates to a digital design method for the shape of a bionic dental crown with individual functions. The steps are: batch scan normal occlusal upper and lower jaw dentition as a standard template database; is the data D1; use the adjacent teeth and opposing teeth in D1 as the common area to match with the data in the standard template database, and select the matching data D2; use the crown data in D2 at the same position as the tooth to be repaired and the data to be repaired Dental preparations were fused to generate initial restoration data; the cusps were staggered and adjusted so that there was no intersection with the opposing teeth; the functional occlusal surfaces of the two adjacent teeth in the mesiodistal and the crowns on the opposite side of the dental arch were extracted , to generate the motion trajectory of the teeth to be repaired; use the envelope surface of the movement of the opposing cusp as the functional occlusal surface shape of the teeth to be repaired. The invention can imitate the process of senior dental experts designing the bionic axial surface, the functional occlusal surface and the physiological wear surface of the tooth, so as to realize the rapid bionic design.

Description

technical field [0001] The invention relates to a three-dimensional design of the most suitable fixed denture shape for the shape of a tooth crown, in particular to a digital design method for the shape of a bionic tooth crown with individual functions. Background technique [0002] The existing digital design methods for the shape of fixed dentures are mainly divided into database method, mirror image method and copy method. Although the anatomical shape of the crown to be repaired can be quickly reconstructed, the ability to design the shape of individual physiological functions is significantly insufficient and has not reached the ideal. bionic design goals. Contents of the invention [0003] The purpose of the present invention is to provide a digital design method for the shape of a bionic crown with individual functions, which can imitate the process of senior dental experts designing the bionic axial surface, functional occlusal surface and physiological wear surfac...
