[Biomechanical study of rigid fixation of the maxillofacial fractures]

Due to the ascending incidence rate of traffic trauma, more and more fractures in oral and maxillofacial region were encountered, which become more severe than before and damage the patient's quality of life and appearance. Biomechanical principles play an extremely important role in treatment of fractures,and study of biomechanical changes of fractured bone before and after rigid internal fixation will improve the effectiveness of therapy. The author summarized the biomechanical studies in the field of rigid internal fixation of fractures in oral and maxillofacial region.
