title: Full arch restoration with computer-assisted implant surgery and immediate loading in edentulous ridges with dental fresh extraction sockets. One year results of 10 consecutively treated patients: guided implant surgery and extraction sockets.
abstract: There is a growing need for patients to be rehabilitated with a fixed, implant-supported prosthesis immediately after surgery. The present study aims to describe the results of a modified prosthetic and surgical protocol of computer-assisted implant insertion and immediate loading in edentulous jaws with extraction sockets. Ten patients were consecutively treated with a modified computer assisted implant surgery protocol and screw-retained provisional metal-acrylic prosthesis prepared ahead of surgery and delivered immediately. Overall, 60 implants (Nobel Replace Tapered Groovy) were inserted, of which 22 were inserted in fresh extraction sockets. Definitive prosthesis was delivered after 6-12 months. Outcome measures were radiographic marginal bone-level changes, survival of implants, and patient satisfaction. The follow-up period was of at least 12 months. All the patients felt comfortable and none withdrew from the study. No implants were lost, resulting in a cumulative survival rate of 100 %. Radiological estimation showed a mean peri-implant marginal bone loss of 1.4 ± 0.3 mm. No other complications, biological or mechanical, were recorded. In all cases, patients appeared to be very satisfied with the aesthetic and function. Within the limitations of this study, our data seem to validate this surgical and prosthetic protocol with valid functional and aesthetic results when applied in selected cases.
