部自由端牙缺陷对假肢设计构成挑战.
了解支组织的应力分布对于长期的假肢成功至关重要.

研究的目的:

评估不同可拆卸部件设计和假肢材料对下自由端缺陷支组织应力分布的影响.
通过使用数字Roach附件,分析部牙周带,牙粘膜和接接口的应力分布.

主要方法:

创建了肯尼迪一级下牙状况的3D模型.
测试了12种假肢模型,将两种可拆卸部件设计与六种CAD/CAM修复材料 (,PEEK,二酸盐等) 结合起来. ) 的情况.
使用三维有限元分析来评估应力分布.

主要成果:

带有扣臂的Roach附着物对牙周带有更高的应力,但对附着接口和粘膜位移的应力降低.
高弹性模量材料,特别是常规和超透光,对固定部件的固定部件表现出有利的结果.

结论:

建议使用带有扣臂的CAD/CAM Roach附件来保护粘膜软组织.
建议使用常规和超透明的合金作为Roach附件的固定部件,用于管理下自由端缺陷.
