无托槽隐形矫治技术——口腔正畸的机遇与挑战

Opportunities and challenges during the development of the orthodontic invisable aligner technique

无托槽隐形矫治技术是20世纪90年代后期出现的一种新兴正畸矫治技术。该技术没有与传统固定正畸技术一样的托槽和矫正弓丝等装置,其生产和加工过程是基于数字化三维重建与快速成型技术等现代先进的高科技技术,使得该技术在美观性、舒适性、便捷性、疗效可预测性等方面均具有无可比拟的优越性,受到国内外口腔正畸界的广泛关注,并在正畸临床治疗中得到不断应用和推广。随着材料学、计算机软件和硬件学、工程制作技术等相关技术的快速发展,无托槽隐形矫治技术在其发展中迎来了一些新的发展机遇;与此同时,作为一个刚刚出现10多年的新技术,其发展与临床应用还面临诸多的困难和挑战。本文对该技术的发展历史、现状以及应用前景进行论述。

The bracketless invisible aligner technique has been considered as a new developed orthodontic technique since its appearance during the period of late 1990s.It is characterized with the advantages of more aesthetic,comfortable,simple,high-efficient and predictable compared with current traditional orthodontic techniques depending on brackets and wires for orthodontic tooth movements.There have been many opportunities for further development and clinical application for the technique with the developments of material sciences,computer software and hardware technology,rapid prototyping techniques,et al.Nevertheless,kinds of difficulties and challenges have been and should be met either at present or in the future for this relatively new technique which just occurred around 10 years ago.The histories,developments with opportunities and challenges and prospects of the technique will be reviewed and discussed in this paper.
