Three-dimensional reconstruction and orthognathic surgery simulation system of craniofacial region based on cephalograms and laser scanning / 华西口腔医学杂志

ABSTRACT

Craniofacial malformation was related to the shape and structure of the teeth, jaws and face. Assessment of craniofacial complex in three-dimensional (3D) has long been a focus for many researchers. At present, 3D imaging techniques could reconstruct the craniofacial soft tissue or hard tissue successfully. However, they couldn't reflect the comprehensive structure of craniofacial complex. For the study of the craniofacial complex, combination of 3D imaging techniques provides a promising way toward optimum 3D imaging. The purpose of this study was to reconstruct the 3D images of craniofacial hard and soft tissue based on cephalograms and laser scanning, to found the 3D measurement and orthognathic simulation and forecast system, which may provide a new method for analyzing of craniofacial malformation, and for the quantity control and evaluation of treatment results in the orthodontic treatment, orthopedics and plastic operation.
