[Precision validation of 3-D reconstruction of the craniofacial hard tissues based on 2-D digital radiograph].

Purpose: In this study, we validated the precision of 3-D craniofacial reconstruction of hard tissues based on 2-D digital cephalometric radiograph, in order to increase the level of orthognathic diagnosis and treatment, and promote communication between doctors and patients.

Methods: Deformation modeling based on 2-D digital radiograph and CT modeling was performed in 7 volunteers. 64 items were measured which described craniofacial hard tissue structure, intuitive overlapping and objective analysis were conducted.

[Development of 3-D reconstruction system of the craniofacial hard tissue based on 2-D digital radiograph].

Purpose: In this study, we used data from digital cephalometric radiograph to develop a 3-D craniofacial reconstruction system. The system was developed by Visual C++6.0, VTK on the platform of Windows XP, to increase the level of orthognathic diagnosis and treatment, and promote the communication between doctors and patients.
