| 摘 要： | 目的研究骨吸收导致的支持骨量减少对精密附着体天然牙- 种植体联合修复应力的影响。方法采用三维有限元分析方法，对支持骨组织有不同程度吸收的精密附着体天然牙- 种植体联合修复模型进行应力计算和分析。结果骨组织吸收、支持骨量减少后各基牙和其支持骨组织中的应力增大，改变明显。结论骨吸收与精密附着体天然牙- 种植体联合修复的应力分布具有密切相关性。

| Abstract: | Objective To investigate the effects of alveolar bone resorption on stress of tooth/implant-supported restoration connected by precision attachment using three-dimensional finite element(FEM) approach.Methods The FEM was applied to analyze the stress distribution of tooth/implant-supported restoration connected by precision at-tachment under various loading conditions when the alveolar bone was absorbed to different level.Results The stress values of the tooth,implant and their surrounding bone increased when their surrounding bone decreased by bone absorption.Conclusion The stress values of the tooth,implant and their surrounding bone were closely relat-ed with the bone resorption. |
