The development of digital dental technology, especially intraoral scanners, has revolutionized the approach to implant prosthetic rehabilitations, enabling more accurate and efficient clinical procedures. The precision of digital impressions is crucial for the success of implant prosthodontic therapy and depends on factors related to both the patient and the therapist. The purpose of this review paper was to analyze how different characteristics of scanbodies for digital impressions, including manufacturing material, geometry, and attachment methods, affect the accuracy of digital impressions. It will also examine how these factors contribute to the quality of the final prosthetic work and will discuss the comparison between the digital and conventional impression protocols in implant prosthodontic therapy. In this systematic review, the methodology is based on a detailed electronic search of scientific databases (PubMed), to identify studies evaluating the accuracy of intraoral scans in the context of implant prosthodontic therapy. Inclusion criteria includedpublished papers that describe in detail the characteristics of scanbodies for digital impressions, including manufacturing materials (PEEK, titanium), geometry (shape, height, diameter, surface), and attachment methods (screw, magnetic, frictional), and their impact on the precision and accuracy of digital impressions. From the review of currently available scientific literature, it is concluded that the best choice for taking a digital impression on an implant is a scanbody made of PEEK, with as simple a design as possible and a clearly indicated scanning area, and screw-retained to the implant.
