Abstract
Introduction: The key to obtaining perfect prostheses depends on the passive fit between its connector and the implant itself. The compromised fit between the contact surfaces of implant-supported prostheses creates uncontrolled stresses in the components and peri-implant tissues, evoking biological and mechanical complications. Objective: It was to review the scientific literature on the types of impression used in implant prostheses. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from July to August 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 111 articles were found, and 44 articles were evaluated in full, and 23 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 06 studies with a high risk of bias and 31 studies that did not meet GRADE. Minimizing contraction appears to be the most important factor in ensuring an accurate impression for this technique. Digital printing has achieved high patient acceptance, reduces possible impression and master mold errors, reduces time in the chair, provides a three-dimensional image of the preparation, and ease of communication between the clinician and the laboratory. However, there is a dearth of scientific data regarding implant fingerprints and their accuracy. Research on implant fingerprinting has been limited to a few in vitro studies and case reports.
