科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙科CAD/CAM技术的使用
数字牙科数字牙科

背景情况:

准确的数字模型对于现代正牙治疗至关重要,包括清晰对齐器治疗.
计算机辅助设计 (CAD) 软件自动化了牙细分,但其准确性需要验证.

研究的目的:

为了比较三种商业CAD软件包中自动牙细分的准确性.
评估牙拥挤严重程度对细分精度的影响.

主要方法:

扫描了三种不同拥挤程度的打字台.
28个单独的牙被扫描为参考 (STL文件).
用2D (点差异,宽度) 和3D (面积,体积) 测量来评估细分精度,并与参考文件和软件 (ArchForm,OrthoSystem,VISION) 进行比较.

主要成果:

大多数测量显示不准确,一般趋势是超大尺寸的细分牙.
拥挤的严重程度并没有显著影响细分的准确性.
软件性能各不相同,OrthoSystem和VISION的准确性高于ArchForm,尽管差异通常不是临床上显著的.

结论:

自动牙细分表现出固有的不准确性,独立于拥挤严重程度.
虽然大多数单点差异在临床上是可以忽略不计的,但 mesial 和牙点,以及 mesiodistal 宽度,显示出明显的高估.
过度估计牙宽度可能会影响清晰对齐器治疗中的近距离缩小计算,可能导致过度切除牙质.
