| 摘 要： | 通过建立套筒冠义齿的三维有限元模型，研究牙槽骨有不同程度吸收时基牙和基托下支持组织所受的应力，并将缓冲型与非缓冲型套筒冠义齿进行比较，为套筒冠义齿用于牙周病的修复治疗提供依据．与非缓冲型套筒冠义齿相比，缓冲型套筒冠义齿对垂直向加载时基牙支持组织及基托下支持组织的应力较小，而且应力在基牙及基托下支持组织的分布更为均匀；随着牙槽骨吸收程度的增加，基牙及基托下支持组织的应力增加，但缓冲型套筒冠义齿可降低其增加幅度．

| Abstract: | With the help of a three-dimensional-limited-element model of telescopic denture, the stress on the supporting tissue of the abutments and denture bases was studied when there was different absorption of alveolar bone. The resilient telescopic denture was compared with non-resilient telescopic denture. The result indicated that the resilient telescopic denture made the stress on the supporting tissue of the abutments and denture bases under vertical forces lower and its distribution more even. With the increasing absorption of the alveolar bone, the stress on the supporting tissue of the abutments and denture bases increased, but the resilient telescopic denture could deduce the magnitude. |
