摘要/Abstract

摘要： 随着微创理念逐渐深入,髓腔固位冠作为根管治疗后的修复方式,因可以保留更多的牙体组织,不切削根管内过多健康牙本质,简便快捷,受到很多医生青睐。髓腔固位冠的强度对牙齿存活率至关重要,因此国内外学者进行一系列实验对其进行研究。该文主要从髓腔固位冠的材料、预备方式、髓腔延伸长度、修复体牙冠厚度等方面对抗折强度的影响作一综述,以期为髓腔固位冠修复根管治疗后的牙齿提供一定的临床依据。

Abstract: In recent years, with the concept of minimally invasive surgery gradually gaining popularity, endocrown has been favored by many doctors as a simple and fast repair method after root canal treatment, because it can retain more tooth tissues without excessively cutting healthy dentin. The strength of endocrown is very important to survival rate of teeth. Therefore, a series of experiments were conducted by scholars at home and abroad to study the fracture strength of endocrown. In this paper, factors influencing the fracture strength of endocrown were reviewed, including materials, preparation methods, length of the pulp chamber extension and thickness of the prosthesis crown, in order to provide some clinical reference for dental restoration after root canal treatment.

Key words: endocrown, fracture resistance, dental restoration, minimally invasive, root canal therapy
