Minimally Invasive Graftless Sinus Lift with Self-tapping Dental Implants for Adults with Missing Upper Back Teeth

What this Trial Is About

Researchers are evaluating a minimally invasive graftless sinus lifting technique using a transcrestal approach combined with dental implant placement in patients who have an edentulous posterior maxilla with limited residual bone height. This study aims to assess the efficiency, safety, and reliability of this approach by examining bone formation beneath the Schneiderian membrane, implant stability, osseointegration, and long-term implant survival. The treatment involves elevating the sinus membrane without using any graft material, relying instead on blood clot formation and natural bone regeneration. Participants with about 4 to 6 mm of residual bone height in the posterior maxilla will receive a dental implant measuring 10 mm in length and 4 to 4.5 mm in diameter during the procedure. This implant placement occurs simultaneously with the sinus membrane elevation. Participants will undergo radiographic and clinical evaluations before surgery, immediately after the procedure, and six months later to monitor bone formation and implant stability. The primary outcome measured is the amount of newly formed bone six months after surgery. Participants are expected to attend follow-up visits as part of the studys monitoring process, which extends through the six-month postoperative period.
