摘要
数字化印模是指使用口内扫描仪在患者口内无需直接接触即获取组织图像,并合成三维牙列影像的印模技术。数字化印模于口腔种植修复中的应用近年来开始受到关注,但其印模精度尚不明确,尤其是多颗种植体的数字化印模精度。本文详细介绍数字化印模的原理、在种植修复不同类型牙列缺损或缺失情况下的精度以及影响精度的相关因素,以期为数字化印模在种植修复中的临床应用提供参考依据。
Digital impression is an impression technique that uses an intraoral scanner to acquire tissue images intraorally without direct contact and synthesize a three-dimensional dentition image. The application of digital impressions in implant dentistry has received more and more attention in recent years, but the accuracy of digital implant impressions is not clear, especially with multiple implants. This article reviewed different principles of intraoral scanners,the accuracy of digital implant impressions and accuracy-related factors, hoping to provide references for clinical application of digital impressions in implant dentistry.
