摘要
有关口腔软硬组织和颜面部软组织的三维形态数据,过去主要是通过物理印模和制取石膏模型来复制牙颌和面部的三维形态并获取其数据,如今随着科学和计算机技术的发展,数字化扫描成为获取其数据的主要方法并逐渐应用于口腔修复领域。其中,三维数字化扫描印模以提高患者的舒适度,数字模型便于储存、整理和远程交流等优点备受青睐。本文就三维数字化扫描技术中的接触式机械扫描、激光扫描、结构光扫描、计算机体层扫描等的原理、特点和应用情况作一综述。
The three-dimensional morphology of oral and facial tissues is obtained by obtaining an impression, followed by plaster model production via conventional methods. Considering the advancements in science and computer technology, digital scanning has been developed and applied in prosthodontics. Three-dimensional digital scanning improves patient comfort. On the other hand, digital models are easy to store, arrange, and use in remote communication. These techniques include contact mechanical scanning, laser scanning, structured light scanning, computed tomography, and so on. This review focuses on the principle, features, and application of these techniques in prosthodontics.
