Abstract

Photoelastic models were used to analyse the effects of stress distribution around post-core systems. Parallel post designs were found to distribute stress more evenly to the tooth root, as compared to tapered posts. Screwed posts were found to be more undersirable.

摘要

采用光弹性模型分析桩核系统周围应力分布的影响。结果发现，与锥形桩相比，平行桩设计能更均匀地将应力分布到牙根。发现螺纹桩更不理想。
