Abstract
The invention relates to a digital design method of a bionic dental crown with individual functions, which comprises the following steps: scanning normal occlusal dentitions and maxillary dentitions in batches to serve as a standard template database; scanning the tooth position preparation body to be repaired, the adjacent teeth and the opposite jaw teeth, and recording as data D1; respectively matching the adjacent teeth and the opposite jaw teeth in the D1 as common areas with data in a standard template database, and selecting matching data D2; fusing the crown data of the tooth position which is the same as the tooth to be restored in the D2 with the tooth position preparation body to be restored to generate restoration initial data; staggered at the cusp
Description
Technical Field
The invention relates to a three-dimensional design of a functionally optimal fixed denture form of a dental crown shape, in particular to a digital design method of a bionic dental crown shape with individual functions.
Background
The existing digital design method for the external shape of the fixed denture is mainly divided into a database method, a mirror image method and a replication method, although the method can realize the rapid reconstruction of the anatomical form of the dental crown to be repaired, the design capability for the external shape of the individual physiological function is obviously insufficient, and the ideal bionic design target is not reached.
Disclosure of Invention
The invention aims to provide a digital design method of a bionic dental crown with individual functions, which can simulate the process of designing a bionic axial surface, a functional occlusal surface and a physiological wearing surface of a tooth by an advanced dental specialist and realize the digital design of quick bionic intelligence of a fixed denture with the most proper function.
In order to achieve the purpose, the invention has the following technical scheme:
the invention relates to a digital design method of a bionic dental crown shape with individual functions, which is characterized by comprising the following steps: comprises the following steps:
1) scanning normal occlusal dentitions and maxillary dentitions in batches to serve as a standard template database;
2) scanning the tooth position preparation body to be repaired, the adjacent teeth and the opposite jaw teeth, and recording as data D1;
3) respectively matching the adjacent teeth and the pair of jaw teeth in the D1 as common areas with each standard data in a standard template database, and selecting a group with the minimum deviation value as matching data D2;
4) fusing the crown data of the tooth position which is the same as the tooth to be restored in the D2 with the tooth position preparation body to be restored to generate restoration initial data;
5) staggered at the cusp
Adjusting to be non-intersecting with the opposite jaw teeth;
6) extracting functional occlusal surfaces on crowns of two adjacent teeth in the near and far and the same area on the opposite side of a dental arch, and generating a functional motion trail of a tooth position to be restored according to the functional occlusal surfaces;
7) guiding the overall virtual movement of the jaw dentition by using the movement track;
8) the envelope surface of the movement of the jaw cusp is used as the functional occlusal surface shape of the tooth to be restored. Thus, the three-dimensional design of the shape of the most functional fixed denture is completed.
The invention has the advantages that: the process of designing the tooth bionic axial surface, the functional occlusal surface and the physiological wearing surface by advanced dental specialists can be simulated, and the digital design of the rapid bionic intelligence with the most suitable function for fixing the false tooth is realized.
