Abstract

There is an increasing demand for techniques that make use of 3-dimensional measurement in the field of dental research. This paper utilized a new 3-dimensional vision system for tooth surface information reconstruction. The system is based on a computational framework for constructing point cloud using digital fringe projection patterns. Surface information extracted from the point cloud can be used in various dental applications, for example, extracting characteristic features, building up a filling model for tooth restoration and determining molar movement during headgear treatment.
