有限元分析在髓腔固位冠修复中的应用进展

Application progress on finite element analysis in endocrown restoration

摘要

随着粘接材料的更新升级、牙髓根治技术的长足进步及修复制作工艺的飞速发展，对于龈距离短、剩余牙体组织少、根管治疗术后死髓磨牙的保存呈现了美好前景。保存天然牙、残冠继续行使功能使得髓腔固位冠的修复理念得到临床医生的接受与认可。利用有限元法进行应力分析具有高效、精确、可重复等优点。本文就有限元法在髓腔固位冠修复中的应力研究应用进行综述，探讨髓腔固位冠修复中的注意事项。

Abstract

The preservation of low occlusal-gingival distance, few residual dental tissues, and dead pulp molar after root canal treatment has good prospects given the updating and upgrading of adhesive materials, the rapid progress of radical pulp technology, and the rapid development of restorative production technology. The preservation of natural teeth and the continuation of residual crown function have made the repairing concept of endocrown accepted and recognized by clinicians. Stress analysis using finite element method has the advantages of being efficient, accurate, and reproducible. This paper reviews the application of finite element method in endocrown repair and discusses precautions in endocrown repair.
