Construction of ideal three-dimensional geometric model of human craniofacial complex

Objective: To develop a kind of digitized method in order to construct three dimensional geometric model which includes 22 bones,all teeth and temporomandibular joints of human craniofacial complex.Methods: A voluntary patient of skeletal class Ⅲ malocclusion in permanent dentition was chosen as a model.Multi-slice spiral CT(SCT) image reconstruction technique and self-programmed were used in combination with ANSYS and Solidworks software.Results: A 3-D geometric model of human craniofacial complex was constructed.It included 22 bones,28 teeth and temporomandibular joints of human craniofacial complex.It could be observed in any dimension.Conclusion: In order to develop a model of human craniofacial complex,the method adopting SCT 3-D image reconstruction technique,ANSYS and Solidworks software was confirmed to be precise and effective.
