Abstract:
Intraoral three-dimensional scanning technology has been adopted in stomatology field and developed rapidly with improved accuracy. At present, the scanning accuracy of the intraoral three-dimensional scanners used in restoration of single crown, three unit fixed partial bridge and single implant crown satisfies the clinical requirements. While for restoration of multi-unit fixed, the scanning accuracy is not enough. There are still technical bottlenecks for scanning functional motion boundary of soft tissue, especially for direct acquisition of edentulous functional impressions. Through literature review and analysis, we summarize the intraoral scanning accuracy of oral hard and soft tissues, and analyze the clinical applicability and limitations of intraoral scanning technology, providing reference for clinical application.
