本文调查70例82件可摘部分义齿的164个(牙合)支托及支托窝,对支托窝底的斜度、支托窝形、支托大小及162个基牙健康情况等,进行统计分析。通过临床实践,提出能够而必须达到的要求。本文重点调查探讨(牙合)支托窝底的倾斜度,调查结果与传统观点不一致,未发现与基牙长轴呈90°或小于90°,平均与长轴垂线呈20°正夹角,据用有限元法应力分析的进一步理论性探讨,证实前磨牙15°、磨牙25°为最佳支托窝斜度,基牙受力最均匀,对临床有指导意义。
In this paper, we surveyed 164 occlusal abutments and support fossa of 70 cases of 82 removable partial dentures. The inclination, the socket shape, the support size and the 162 abutment health of the abutment were investigated. conduct statistical analysis. Through clinical practice, put forward the requirements that can and must be met. This paper focuses on investigating the inclination of the bottom of the occlusal support, the findings are inconsistent with the traditional view, did not find with the long axis of the abutment was 90 ° or less than 90 °, with an average of 20 ° perpendicular to the long axis positive angle According to the further theoretical study of stress analysis by finite element method, it was confirmed that premolar 15 ° and molar 25 ° are the best supporting socket inclination, and the abutment force is the most uniform, which is of clinical significance.
