Abstract

The structure of dental implant is very important to its service life. In order to investigate the effect of the biomechanical properties of anchored dental implant on the osseointegration strength and secondary stability of dental implant, a dental implant model was established based on the three-dimensional structure of human oral cavity, craniomaxillofacial region. Static analysis of dental implant under static load was carried out by using ANSYS finite element analysis software. The results show that the anchorage structure dental implants have better biomechanical compatibility than the traditional standard dental implants, and can improve the strength of the bone-bonding interface. At the same time, the side of the anchorage structure can share the stress of the alveolar bone-implant interface and reduce the risk of unintentional bone-implant damage, so as to ensure the secondary stability of the dental implant, and can better limit the degree of freedom of movement of the dental implant, indirectly promote the restoration of bone-implant injury by reducing the fretting of the dental implant.

支抗结构种植体修复上切牙缺失的生物力学特性

种植体的结构对其使用寿命有重要影响。为了研究锚定种植体的生物力学特性对种植体骨结合强度和二次稳定性的影响，基于人口腔、颅颌面区域的三维结构建立了种植体模型。采用有限元分析软件ANSYS对种植体进行静载荷作用下的静力分析。结果表明，该固支结构种植体比传统标准种植体具有更好的生物力学相容性，并能提高骨结合界面的强度。同时，侧支抗结构可以分担牙槽骨-种植体界面的应力，降低无意中造成种植体骨损伤的风险，从而保证种植体的二次稳定性，并能更好地限制种植体的运动自由度，通过减少种植体的微动间接促进种植体骨损伤的修复。
