正畸过程中牙齿三维方向变化的模型测量方法研究进展
Research Progress of Model Measurement Methods for Three-dimensional Orientation Changes of Teeth During Orthodontics
摘要
Abstract
The evaluation of tooth movement efficiency in three-dimensional direction is one of the important contents to evaluate the orthodontic effect.With the development of technology and the continuous progress of appliance and orthodontic technology,the methods and tools used to study the three-dimensional movement efficiency of orthodontic teeth are constantly updated.Taking the development of tooth movement measurement as the main line,this review introduces the process and basis of changing from manual plaster model measurement to computer software measurement of digital dental model.It also explains the data acquisition mode,storage file format and optional analysis and processing software of three-dimensional digital model,and reviews some previous studies on three-dimensional superimposition of three-dimensional digital dental model.In this review,the commonly used registration methods and the selection of registration region for two kinds of 3D model data obtained by optical scanning and X-ray scanning are summarized.关键词
