Abstract:
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.
