【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]:Aim: to study the fatigue life of different abutment materials in conical locking column structure platform transfer implant system by three dimensional finite element method. Methods: the three dimensional finite element model of the first mandibular molar supported by the implant was established and the fatigue life of different abutment materials was analyzed. Results: the fatigue life of different material platform was zirconia base platform. Conclusion: the fatigue life of titanium, alumina and zirconia base is more than 30 years. The key to determine the fatigue life of different materials is the stress concentration point, that is, the joint between the base and the implant.
