摘要/Abstract

摘要： 牙体缺损修复中,通过口内扫描获取数字化印模的技术以其简单、舒适、快捷的特点越来越多地被应用于临床。数字化印模的精度(包括正确度和精密度),是影响修复体密合性和修复最终成败的关键。各种口内扫描设备扫描原理不同,扫描精度有所不同。另外,临床操作中采取的扫描方案、预备体质量和口腔环境等因素都会影响到扫描精度。了解口内扫描原理和扫描精度相关影响因素,在临床操作中采取相应的应对策略可以提高扫描精度,最终提高牙体缺损数字化修复的成功率。

关键词: 口内扫描, 精度, 正确度, 精密度

Abstract: In tooth defect restoration , the technology of obtaining digital impression through intraoral scanning is used more and more frequently in clinical practice because of its simple, comfortable and fast characteristics. The accuracy of digital impression (including trueness and precision) is the key to final success of restoration. The scanning accuracy is different because of different scanning principles of various intraoral scanning equipment. In addition, the scanning scheme adopted in clinical operation, preparation quality and oral environment will all affect scanning accuracy. Understanding the principle of intraoral scanning and relevant influencing factors of scanning accuracy, and taking corresponding coping strategies in clinical operation can improve scanning accuracy, and then eventually improve the success rate of digital restoration of tooth defects.

Key words: intraoral scanning, accuracy, trueness, precision
