摘要/Abstract

摘要：

易于人（医师和技师）或机器（口扫和仓扫等）辨识的清晰的肩台是固定修复体获得良好长期稳定的治疗效果的关键。牙体预备肩台的制备方法以徒手和经验为主,缺乏全面客观的术前设计、术中核查及最终检验,肩台预备术的精度亟待提升。本文详细提出了可获得高预备精度的“三定三选三步”的临床路径,以及“车针尖端引导”的精准肩台预备法则和方法。

Abstract:

A clear shoulder platform that can be easily identified by doctors and technicians or machines (mouth scan and warehouse scan) is important to obtaining a good long-term and stable fixed prosthesis treatment effect. At present, the preparation of the shoulder platform is usually based on free hands, and the practical operation is mainly guided by experience. Moreover, no comprehensive and objective preoperative design, intraoperative verification, and final test are available. Thus, the accuracy of shoulder platform preparation needs to be improved. In this study, the clinical pathway of “three determination, three selection, and three steps” with high accuracy of preparation and the precise shoulder preparation method of “bur-tip guidance” are proposed in detail.

Key words: tooth preparation, tooth shoulder platform, clinical pathway, precise restoration, esthetic dentistry
