Full-mouth rehabilitation with immediate loading of implants inserted with computer guided flap-less surgery: a 3-year multicenter clinical evaluation with oral health impact profile

Objective: The purpose of this report is to present the clinical outcomes and patients' satisfaction of full-mouth rehabilitation using computer-aided flapless implant placement and immediate loading of a prefabricated prosthesis.

Materials and Methods: The study included 30 consecutive fully edentulous patients who received 312 implants. Mandible and maxilla were treated in the same surgical session with computer-guided flapless approach using the NobelGuide protocol. Prefabricated screw-retained fixed prostheses were inserted at the end of surgery. Clinical and radiographic evaluations were assessed at 6, 12, and 36 months. At baseline and 6 months after surgery, patients answered Oral Health Impact Profile in Edentulous Adults questionnaire to assess satisfaction.

Results: The implant survival rate was 97.9%, whereas the average marginal bone loss was 1.9 +/- 1.3 mm after 3 years. At 6 months, patients showed significantly greater satisfaction with their fixed rehabilitation when compared with conventional dentures.

Conclusions: The results of this study confirm that rehabilitation with a prefabricated fixed prosthesis supported by implants placed with NobelGuide protocol is a viable and predictable treatment and increases patients' satisfaction and improves oral health-related quality of life.
