In this study, 27 patients were taken, in 3 groups of 9 patients, who addressed to dental offices in which were implantologists with 1 year (group A), 6 years (group B) and 11 years (group C) of experience in surgery. Lot A, operated by a 1-year physician with experience in implantology, had the smallest deviation, demonstrating the increased attention that he had to the interventions. Comparing B and C lots, the smallest deviations were recorded for group C, operated by implantologist with greater experience in implantology. By comparing the deviations according to the type of surgical guide used, the smallest deviations at the apex and prosthetic platform were made in patients where the implants were inserted with a bone supported guide, followed by dental-gingival and mucosal guide. In terms of axis of implantation, the lowest values were recorded for the dental-gingival guide, followed by the bone and mucosal guide. The study has a number of limitations (low number of patients undergoing study, low dispensation period), which requires more extensive future studies to validate the results.
