Abstract

Intra oral scanning or IOS is a relatively new method of fabricating the removable prosthetic that promises to make the conventional impression obsolete. This narrative review will be an attempt to compare and describe the existing reported applications of IOS in fabrication of different types of removable prostheses in prosthodontics and its effectiveness. An electronic database search was carried out in PubMed, MEDLINE, Scopus, and Embase with emphasis on articles from January 2013 to March 2024. The review looked at in vitro studies and clinical reports on DI, CDI and various forms of DDs and DP. Thus, patients expressed a significantly higher level of preference for the digital scanning technique over conventional impression taking methods in terms of discomfort, nausea, and breathing problems. It has been most beneficial in the fabrication of RPD’s, and implant supported prostheses with better fit of the prosthesis. Nevertheless, the usage of IOS in complete dentures remains somewhat limited and weakens through the difficulties in capturing edentulous arches properly. Thus, even if IOS technology has high initial costs and initial difficulties, in the long run, it can be a useful instrument to improve the work of a contemporary dental practice. Thus, it can be concluded that further investigations are required to fill the existing gap and introduce the intraoral scanner for additional applications in removable prosthodontics. This review will also extend IOS’s applicability of supporting prosthodontic practice to increase patient benefits and enhance the fabrication process.
