Abstract

The restoration of endodontic tooth is always a challenge for the clinician, not only due to excessive loss of tooth structure but also invasion of the biological width due to large decayed lesions. In this paper, the 7 most common clinical scenarios in molars with class II lesions ever deeper were examined. This includes both the type of restoration (direct or indirect) and the management of the cavity margin, such as the need for deep margin elevation (DME) or crown lengthening. It is necessary to have the DME when the healthy tooth remnant is in the sulcus or at the epithelium level. For caries that reaches the connective tissue or the bone crest, crown lengthening is required. Endocrowns are a good treatment option in the endodontically treated tooth when the loss of structure is advanced.

摘要

牙髓病牙齿的修复对临床医生来说始终是一项挑战，这不仅是因为牙齿结构大量丧失，还因为大面积龋损侵犯了生物学宽度。本文研究了II类洞型更深的磨牙中7种最常见的临床情况。这包括修复类型（直接修复或间接修复）以及洞缘的处理，例如是否需要深部边缘提升（DME）或牙冠延长术。当健康的牙体残余位于龈沟或上皮水平时，有必要进行深部边缘提升。对于到达结缔组织或牙槽嵴的龋齿，则需要进行牙冠延长术。当结构丧失严重时，内冠是牙髓治疗后牙齿的一种良好治疗选择。
