摘要

牙冠置换一直是安装固定义齿的困难方法之一,但由于美观因素和生物宽度的侵袭而经常被采用。本文将重点讨论原有牙冠边缘存在缺陷的临床情况。鉴于临床上对修复管理和牙周组织的决策必须谨慎,本文提出了一个决策树,说明了在牙冠边缘已有缺损的美学区域使用天然基台的决策过程。新冠边缘的重建是新修复体成功的关键,新边缘应位于适当的美学位置和正确的生物学位置。新边缘应具有精细、光滑和连续的形态。

Clinical solutions for natural abutments with preexisting defected crown margin in the aesthetic area.

Crown replacement has remained one of the difficult methods for installing fixed prosthesis but is often performed because of aesthetic factors and invasion of biological width. This article focuses on the clinical scenario in which preexisting crown margin has defects. Given that clinical decisions regarding restoration management and perio-dontal tissues have to be made with caution, a decision tree of the decision making process for natural abutments in aesthetic area with preexisting defected crown margin is presented. The re-establishment of a new crown margin is the key to the success of a new restoration, and the new margin should be located at the proper esthetic position and right biological position. It should have fine, smooth, and continuous morphology.
