Abstract

The introduction of surgical techniques based on the exploitation of ultrasonic vibrations has made it possible to obtain important innovations in all dental fields. The present study aims to evaluate implant survival ten years after definitive prosthetic rehabilitation on implants inserted in a second surgical stage compared to the maxillary sinus lift performed using piezosurgery technology and the application of a graft taken from the iliac crest. A total of 8 patients were selected, aged between 25-70 years, awaiting implant-prosthetic rehabilitation of the postero-superior sectors, but with anatomical conditions initially not favorable to implant insertion. The total number of implants inserted is 42, of which 20 support a screw-retained prosthesis and 22 support a cemented prosthesis. They underwent a 10-year evaluation, positioned in two surgical stages in the posterior sectors of the maxilla. Of the 42 implants inserted, 2 were lost during the osseointegration phase. Once removed and reinserted, they showed no sign of failure at the second 5-year follow-up. In the remaining 40 implants inserted, after 1 and 5 years, stable implant osseointegration occurred. At 10 years, only 2 more implants were lost. The ten-year implant survival percentage of implants inserted six months after maxillary sinus lift, performed using piezoelectric technology and insertion of autologous bone from the iliac crest, appears very valid and in line with that obtained from numerous reviews of the literature on large sinus lift.
