正畸托槽定位方法的研究进展

正畸托槽的精确定位是取得快速、理想矫治效果的必要条件。随着正畸技术的日益成熟及计算机技术在口腔正畸领域的广泛应用,各种提高托槽定位精确度的方法如间接粘结技术及计算机辅助的托槽定位应运而生。与口内直接定位或石膏模型上间接定位技术不同的是,三维整合数字化模型可以虚拟托槽定位、模拟矫治过程和预测矫治结果,使得托槽定位更加准确,节省了临床操作时间。本文对托槽粘结位置、直接定位方法、间接定位方法等方面的研究进展进行综述。
Accurate bracket placement is essential for efficient and ideal orthodontic treatment. Due to the extensive integration of computer technology into orthodontics, computer-aided positioning brackets and variable methods of indirect bonding develop rapidly, aiming to position the brackets more correctly and simply. Compared with direct bonding and indirect bonding based on plaster models, three-dimensional digital maxillofacial-dental models have the advantage of simulating the virtual bracket position and the whole treatment process, predicting the final treatment outcomes, consequently, allowing for more accurate bracket positioning and less chair time. Here we reviewed the recent development of bracket placement, direct and indirect positioning technique in orthodontics
