Abstract

The invention provides a dental occlusion surface recovering method. The method includes the steps that the vertexes on the residual occlusion surface of an inlay preparation and projection points, on a standard tooth model, of the vertexes are obtained, the projection points are dispersed to the corresponding vertexes, and the projection points are moved to a standard tooth by carrying out Laplacian deformation on the standard tooth so that the standard tooth can be tightly attached to the inlay preparation; as Laplacian deformation is carried out multiple times, model self-crosslinking can be prevented, and moreover key information of fossa, groove, cusp and ridge on the residual occlusion surface is retained.

Description

technical field

[0001] The invention relates to the field of denture restoration, in particular to a tooth occlusal surface restoration method and system. Background technique

[0002] Prosthodontics has found through statistical surveys that although there are differences in human teeth, the general shape is basically similar. Therefore, based on a large number of statistics, a set of standard dental banks has been summarized. Each individual tooth can correspond to the teeth in the standard dental bank. A standard tooth.

[0003] In the prior art, when a defective tooth needs to be repaired, the defective tooth is usually repaired based on the residual part of the defective tooth and the standard tooth. curve) surface fitting technology to obtain the complete occlusal surface of the residual part, but the dimples, grooves, cusps, and ridges on the occlusal surface of the teeth are randomly distributed, and only relying on NURBS surface fitting technology will lead to dimp...
