摘要: 髓腔固位冠(endocrown)是一种利用髓腔固位的根管治疗后牙体修复的方式。其既可利用髓腔进行机械固位,又可利用修复体与牙面较大的接触面积进行粘结固位。近年来随着修复材料及粘结技术的发展,髓腔固位冠由于其备牙量少、椅旁操作时间短等特点得到国内外学者的关注。本文就髓腔固位冠的定义、适用范围、牙体预备、机械性能、材料选择及其临床研究等方面对现有的研究结果进行了系统的回顾和分析。

Abstract: Endocrown was defined as a restoration fixed to a depulped tooth, which was anchored to the internal portion of the pulp chamber and to the cavity margins, thus obtaining macromechanical retention (provided by the pulpal walls), and microretention (by using adhesive cementation). As the development of restorative materials and adhesive techniques, endocrown received increasing attention due to its minimal tooth preparation and reduced chair-side time. This paper reviewed recent researches about endocrown in the aspect of its definition, indications, tooth preparation, materials, and performance compared to crown and post-and-core crown.

Key words: Endocrown, Endodontically treated teeth, Posterior, Ceramic
