Abstract:

The analysis of maxillofacial soft tissue is closely related to the aesthetic effect and stability of orthodontic treatment. Three dimensional stereophotogrammetry is an important tool for orthodontists to conduct soft tissue analysis. Most of the three-dimensional photogrammetric devices have acceptable accuracy and reproducibility, and are widely used in orthodontic diagnosis, treatment planning, treatment monitoring and postoperative evaluation. With the development of computer technology and the arrival of big data era, the stereophotogrammetry technology has bright prospects in terms of promoting imaging capability, enriching software functions, enhancing user friendliness, developing automation technology and establishing and improving databases.

Key words: soft tissue analysis, three dimensional stereophotogrammetry, orthodontics
