超声器械在肩台预备中的应用现状和研究进展
Research progress on ultrasonic instruments applied in refined margin shoulder preparation

摘要： 随着固定修复肩台预备要求的不断提高,近年来,超声器械被用于牙体预备肩台的精修中,其良好的肩台光滑效果顺应了口腔固定修复精细化发展的趋势,而超声器械在肩台应用领域的研究目前仍以体外实验为主,本文就国内外超声器械在肩台预备应用中的研究进展进行回顾、分析和展望。
Abstract: In recent years, ultrasonic instruments have been applied for margin shoulder refining with higher standard raised in fixed prosthesis. It’s excellent effects in smoothing margin shoulder complied with the precision trend. While the in vitro research occupied an predominant position in relevant aspects. This article was written to conduct a retrospective analysis and develop future tendency on application of ultrasonic instruments in margin shoulder perfection.
