Assessment of Different Intraoral Scanners in Intracoronal Preparations: A Systematic Review.

There are no systematic reviews on assessing the accuracy of intraoral scanners in scanning the intracoronal preparations, so this systematic review aims to assess the accurate intraoral scanner in scanning intracoronal preparations aiming to assist Dental professionals in producing improved fit of inlays, onlays and endocrowns. The objective of this Systematic Review is to assess the Accuracy of different intraoral scanners in capturing images of intracoronal preparations like inlays, onlays, and endocrowns. Literature searches were performed up to April 2024 in Cochrane, PubMed, web of science, Google scholar, Embase, Scopus, databases. Article selection was determined by adherence to inclusion and exclusion criteria. The primary criterion for article selection is “Accuracy, Trueness & Precision of Intraoral scanners in scanning the Intracoronal preparations”. The secondary condition is “Accuracy of the scanners in reproducing the details of the inlays, onlays and endocrowns during intracoronal preparations.” 20 studies out of 10,666 Potentially pertinent records were incorporated into the qualitative synthesis. Eleven in vitro studies and one in vivo study account Trios has better Trueness and Precision where as Six in vitro studies interpret trueness and precision of CEREC® Primescan and five studies infer that Carestream CS3500 has improved trueness and precision. This systematic review indicates that the Trios (3Shape) intraoral scanner demonstrates superior accuracy compared to other intraoral scanners, with CEREC® Primescan intraoral scanner following closely behind, particularly in terms of trueness and accuracy. Various additional factors should be taken into account, such as the size of the preparation, tooth location, presence of saliva, and operator's experience, all of which exert a significant influence on the accuracy of intraoral scanners. Further research and development of these intraoral scanners must be conducted for further clinical settings.
