Abstract:

The wide application of digital scanning technology in the field of dentistry has made medicine more modern and convenient. It has become popular to obtain digital face models through facial scanning systems. In order to reproduce the perfect maxillofacial shape and proportion, accurate facial scanning equipment is indispensable. For all kinds of facial scanners on the market, their working principles and scanning characteristics are not the same. This article will summarize the development of digital facial scanning technology, introduce different technical principles and discuss the clinical application, and look into the application prospect of this technology in the medical field. The limitations of this technology are proposed, in order that the digital facial scanning technology can be better applied in clinical practice.

Key words: facial scanning, 3D stereophotogrammetry, stomatology
