摘　　要：随着种植技术和数字化技术的快速发展,口内数字化印模已是口腔种植修复中常用的印模方法。目前,口内数字化印模直接应用于无牙颌患者种植修复的准确性尚有所缺欠,这是由于无牙颌种植印模的准确性要求较高,而口内数字化印模尚存在识别和拼接的技术难点。对此,学者们提出了多种优化扫描策略的方法,如黏膜修饰法、辅助结构法、改良扫描杆法等,可在一定程度上提高无牙颌种植口内数字化印模的准确性。同时,立体摄影测量作为一种新兴的数字化印模方法正逐步发展成熟,准确性良好。本文从无牙颌种植修复口内数字化印模的准确性研究现状出发,综述了提高无牙颌种植口内数字化印模准确性的策略,以期为临床应用提供参考。With the rapid development of implant techniques and digital technology,intraoral digital impressions have become a commonly used impression method in implant restoration.At present,the accuracy of intraoral digital impressions directly applied to implant-supported prostheses in edentulous jaw remains inadequate.This is due to the high accuracy requirement of full-arch implant impressions,while there are still technical challenges in intraoral digital impressions about recognition and stitching.In this regard,scholars have proposed a variety of scanning strategies to improve the accuracy of intraoral scans,including mucosal modifications,auxiliary devices and novel scan bodies.At the same time,as a new digital impression technique,stereo photogrammetry has been developing steadily and exhibits promising accuracy.This article reviews the research progress on the accuracy of edentulous full-arch implant impressions and techniques which can improve the accuracy of intraoral digital impressions thus providing a reference for clinical application.
