基于牙体牙髓、牙周及功能健康的 显微微创牙体预备

牙体预备技术是口腔美学修复治疗必知必会的核心操作,通过一定量的牙修复体组织的磨除,为目标修复体提供容纳空间、粘接面与完成线等。如何在完成高质量牙体预备的同时还能保存牙体、保护活髓和牙周组织是美学修复牙体预备中亟需解决的难题。本文就微创牙体预备的概念及核心要素,显微牙体预备涉及的解剖生理学、显微牙体预备术前设计进行介绍,并总结了显微牙体预备技术临床路径,提出了显微牙体预备核心因素——量与形的新认知。

Minimal invasive microscopic tooth preparation based on endodontic,periodontal and functional health

Tooth preparation is the primary and core operation technique for dental esthetic restoration treatment, due to its effect of providing restoration space, bonding interfaces and marginal lines for dental rehabilitation after tooth tissue reduction. The concept of microscopic minimal invasive dentistry put forward the issue of conducting high-quality tooth preparation, conserve tooth-structure, protect vital pulp and periodontal tissue simultaneously. This study reviewed the concepts, physiology background, design and minimal invasive microscopic tooth preparation, and in the meantime, individualized strategies and the two core elements of tooth preparation (quantity and shape) are listed.
