Sinus floor lift and simultaneous implant placement: A retrospective evaluation of implant success rate

The purpose of the present retrospective investigation was to evaluate the survivability and success of implants placed simultaneously during direct sinus lifts with allograft forms of bone with a follow up from one to four years. 110 patients were included in this study. A radiological evaluation was done before the surgical treatment by a OPG and intraoral radiographs. A cone beam CT was done when it was indicated. All patients received a sinus lift surgery with a contemporary implant placement. Success and failure rate was recorded in a follow up from one year to four years since the implant placement. Maxillary sinus surgery is a reliable and predictable treatment option for the prosthetic rehabilitation of the atrophic maxilla. A correct surgery planning is a way to avoid post-operative complications and to an adequate prosthetic rehabilitation. Implant success, in this retrospective study is 97.7% at 1 year follow up and 96.9% at 2 years follow up. Prosthetic success at a 4 year follow up (115 prosthetic treatment in 108 patients) has been 98%. A complete pre surgical planning and careful patient selections can produce a predictable results for implant prosthesis treatment.
