PURPOSE: To evaluate the trueness of two intraoral scanners in different clinical situations and considering operator experience. MATERIALS AND METHODS: Two intraoral scanner systems were used to perform a total of 120 digital impressions of three master casts reproducing three scenarios (single implant, two implants, and four implants [full-arch]). Two operators, one experienced and one unexperienced, were selected. RESULTS: No differences were found between the two operators. A statistically significant correlation was found with regard to the scanning system used and the clinical scenario analyzed. CONCLUSIONS: Within the limits of this preliminary report, operator experience seems not able to significantly influence the trueness of a digital impression; however, imprecision increased in the full-arch cases for both operators. The twoimplant scenario presented similar trueness values for both scanner systems.
