Over the last 37 years, crown-lengthening procedures have been used predictably to restore teeth broken down from caries, trauma, and extensive wear. With crown lengthening, the dentogingival junction is "re-created" at a more apical level on the root to accommodate the junctional epithelium and the connective tissue attachment. Forced eruption can be used in addition, or as an alternative, to tooth lengthening. The authors discuss the indications for tooth lengthening, forced eruption, and orthodontic extrusion, as well as the treatment planning for these procedures.
在过去的37年里，冠延长术已被可预测地用于修复因龋齿、外伤和严重磨损而损坏的牙齿。通过冠延长术，在牙根上更根尖的水平“重新创建”牙龈牙本质界，以容纳结合上皮和结缔组织附着。此外，或作为一种替代方法，可使用强制萌出术来延长牙齿。作者讨论了牙齿延长、强制萌出和正畸压出的适应症，以及这些手术的治疗计划。
