摘要/Abstract

摘要：

全冠拆除常需花费大量临床时间，尤其是氧化锆全瓷冠的拆除。树脂粘接剂的界面难以分辨，使用高速手机拆除时容易对剩余牙体组织造成损伤，影响再次修复效果。本文报道了1例纤维桩、树脂核和高透氧化锆全冠修复后，因美观需求重新修复的病例。使用Er:YAG激光完整拆除氧化锆全冠，并作为临时修复体继续使用。基牙和软组织未受损伤，再次修复效果满意。结果提示使用Er:YAG激光拆除旧修复体是一项安全、高效的方法。

关键词: 激光, 氧化锆, 全冠

Abstract:

The removal of a full crown typically requires considerable chairside time, and the interface between zirconia and resin cement in zirconia restoration is difficult to discern. A high-speed dental handpiece may damage residual dental tissue, thereby affecting the final outcome. The article presents a case after a restoration involving a fiber post, resin core, and zirconia full crown. For esthetic purposes, the removal of the full crown is necessary. An Er:YAG laser was used to completely remove the intact crown, which was then used as temporary restoration. A satisfactory esthetic result was attained after the final restoration. The case suggests that crown extraction with an Er:YAG laser is a safe and effective technique.

Key words: laser, zirconia, full crown
