Análise comparativa de diferentes marcas de escâneres intraorais na precisão e veracidade do escaneamento de próteses sobre implantes: revisão de literatura

Abstract

INTRODUCTION: Intraoral scanners were created with the purpose of optimizing clinical steps, offering more precision, practicality, and comfort. They are used in several applications in dentistry, one of which is dental prosthesis implant-supported. OBJECTIVE: The objective of this study is to present, compare, and evaluate, through a literature review, the precision and veracity of different brands of intraoral scanners in implant-supported prosthesis. METHODOLOGY: The bibliographic search was restricted to the electronic database: PUBMED, from February 2024 to July 2024, using the following filters: publication date [January/2019 – July/2024], language [English], descriptors (terms) and their respective combinations: (“intraoral scanners and intraoral rehabilitation”, “intraoral scanners dental implant prosthesis and intraoral scanning”). RESULTS: A total of 368 articles were identified and analyzed according to the inclusion and exclusion criteria, and 8 were included in the analysis. The studies highlight that the scanners with the best levels of accuracy are: Cerec Primescan and Trios 3. In terms of accuracy, they are: Cerec Primescan, Trios 3 and Trios 4. CONCLUSION: It can be concluded that more in vivo studies are necessary for a more accurate analysis, since most of the articles identified are in vitro studies, which limits their clinical significance, since some details such as the tongue, cheek and saliva can make a difference in the quality of the scan. In addition, the operator's experience is one of the factors that makes a difference in the accuracy of the scan with any brand of scanner.
