天然牙联合种植体支持可摘局部义齿修复多数牙缺失，可以解决KennedyⅠ、Ⅱ类牙列缺损（特别是有多数牙齿的缺失）情况下，可摘局部义齿在固位、稳定、支持方面存在的问题。同时，这类修复方法也可作为由于患者骨组织或经济原因不能行固定种植义齿修复的一个很好的选择。然而，有关这类修复的基础研究与临床报道比较少，且仍缺乏系统性。本文从生物力学及临床设计须注意的问题两个方面对此进行初步的阐述。

The restoration of multiple teeth missing with removable partial denture supported by a combination of implant and nature teeth

With regard to partial edentulism with free end （the Kennedy Class I and Class I ） , particularly for those patients who have multiple teeth missing, the removable partial denture supported by a combination of implants and natural teeth is a good solution which may provide sufficient retention, stability and support. And this treatment method can also be a good alternative for the patients who are not suit- able to receive the treatment of implant supported fixed den- ture because of bone resprotion or economic limitation. Howev- er, the related basic research and clinical reports are still rare and not systematic. This paper discussed two aspects of this new treatment method, including biomechanics and clinical design.
