Intraoral restoration digital design method based on big data

Abstract

The invention provides an intraoral restoration digital design method based on big data. The invention belongs to the field of dental restoration and restoration processes. Customizing a dental characteristic data distance function; obtaining jaw model characteristic data P2 closest to the current jaw characteristic data P1, and taking jaw model entity data M2, the current jaw model data M1 and the current jaw characteristic data P1 of samples where P2 and P2 are located as inputs of a non-rigid point matching algorithm to obtain a transformation function T21; finally, the transformation function T21 acts on D2, and a design scheme D1 is obtained through a self-adaptive surface fitting algorithm and serves as reference for prosthesis technicians. According to the method, excessive manual interactive design operations in the prior art are greatly reduced, and the design level, the design efficiency and the design precision of operators are quickly improved.

Description

technical field [0001] The invention belongs to the field of oral restoration and restoration technology, and in particular relates to a digital design method for intraoral restorations based on big data. Background technique [0002] Although the existing digital design of intraoral restorations can meet the requirements of digital design; however, due to too many manual interactive design operations in the design software, first, the design efficiency is low; second, too many manual interactive design operations lead to design accuracy The design effect is not high, and the design effect is excessively dependent on the operator's experience and operating skills, and sometimes it needs to be redesigned to complete the design task; third, it takes a long time to accumulate expert experience, and junior technicians need to memorize a large number of cases to design qualified products. Contents of the invention [0003] In view of the deficiencies in the prior art, the prese...
