Abstract

Fifty Flexi-Posts were cemented in extracted teeth and tested for tensile strength. The Flexi-Post was the most retentive post tested when compared with posts used in a similar study. The retention of the Flexi-Post became greater as the size of the post increased.

摘要

五十根弹性桩被粘结在拔除的牙齿中，并测试其拉伸强度。与一项类似研究中使用的桩相比，弹性桩是测试中固位力最强的桩。随着桩尺寸的增加，弹性桩的固位力变得更强。
