Abstract:

BACKGROUND: Cranial-maxillary complex is one of the most complex and versatile structure in the skeletal system. For the biomechanical analysis of cranial maxillary complex, it is necessary to establish a precise three-dimensional finite element model
OBJECTIVE: To develop an effective and feasible method to construct the three-dimensional finite element model of cranial-maxillary complex. 
METHODS: A voluntary healthy adult with normal relationship, healthy periodontal tissues and temporomandibular joint was chosen for model establishment. Multi-slice CT scan in combination with Mimics software and MSC.Patran software were used to prepare the three-dimensional finite element model of cranial-maxillary complex.
RESULTS AND CONCLUSION: We had explored out a new quick construction method of maxillary complex. A 3D FEM of normal maxillary complex was constructed. It included 76 035 nodes and 373 819 elements. It could be observed at any dimension. The finite element model had better biomechanical characters.
