摘要: 目的:通过三维有限元法了解锥形锁柱结构平台转换种植体系统不同基台材料疲劳寿命。方法:建立平台转换连接种植体支持的下颌第一磨牙三维有限元模型,分析不同基台材料疲劳寿命。结果:不同材料平台转换连接基台的疲劳寿命均是钛基台>氧化锆基台>氧化铝基台。结论:钛基台、氧化铝基台和氧化锆基台的疲劳寿命均在30年以上,决定不同材料基台疲劳寿命的关键是其应力集中点,即基台与种植体连接处。

Abstract: Objective: To realize the fatigue life of taper lock abutment in platform switching implant with different materials. Methods: The image making software was used to set up the three-dimensional finite element models which simulated the platform switching abutment connection with alveolar bone complex. Results: The rank of fatigue life of these different implant abutment materials was titanium>zirconia>alumina. Conclusion: The fatigue life of these implant abutment materials were over 30 years. The key factor of different material fatigue life is the point of stress concentration.
