Abstract


Purpose: To evaluate the changes in the bone crest around the implants with abutments with platform-switched in a retrospective clinical investigation derived from a previous study. Materials and Methods: Twenty-six healthy patients mean age of 51,6 ± 11,4 with one or more missing teeth were consecutively treated with Prevail implants, with and without platform-switched, conical, and with complete treatment. A total of 68 implants were placed test group with a prevailing implant with platform-switched (34 implants) and control group with the prevailing implant without platform-switched (34 implants). The final restorations were delivered 4 to 11 months after the insertion of the implant. Digital standardized periapical radiographs using customized film holders were obtained at the time of implant insertion and 12 months after. Marginal levels of peri-implant bone were measured on the mesial and distal surfaces of each implant using digital imaging software. Results: All the osseo integrated implants were clinically stable at the 12-month follow-up. The cumulative survival rate was 100%. The average bone loss was 1,34 ± 1,02 mm on mesial and 1,57 ± 0,99 mm on distal for the control group and 0,56 ± 0.85 mm on mesial and 0,82 ± 0,92 mm on distal for the test group. There are no significant differences related to sex, implant site, and bone density. Conclusion: The results of this study suggest that using implants with platform-switched may be effective in conserved the crestal bone level, reducing bone loss, and preserving the aesthetics of peri-implant tissues.
