摘要
Abstract
Objective: To explore the biomechanical theory basis in order to search for the best clinical treatment methods of first mandibular molar, through the stress and strain of local and overall jaw bone are analyzed with the finite element method. Methods: Based on a CT data of an adult jaw bone, the mandibular model was built with Mimics14.11 software. 50N of the buccolingual 45°force was given on first mandibular molar. The stress and strain change of manduble were analyzed with finite element analysis software ABAQUS6.9-3. Results: When the buccolingual 45° force is given on first mandibu-lar molar, the most strain and stress of local bone are in the jaw bottom turn to buccal. For the whole manduble, stress and strain first mainly concentrated in the first molar, the second in the opposite side of the mandibular Angle. The conduction of stress and strainb is along cross-court. mandibular. Con-clusions: The finite element analysis method can be used for the first molar mandible mechanical anal-ysis, and reveal the biomechanics mechanism of the physiology and pathology process for mandibular factors.关键词
