Randomized Trial Comparing Bone Implant Methods in Upper Jaw Sinus with Osseodensification or Lateral Window Techniques

What this Trial Is About

Researchers are comparing two methods for placing dental implants in adults with a single missing tooth in the back upper jaw, where the remaining bone height is between 3 and 5 mm. The study evaluates patient-reported outcomes, complication types and rates, and bone loss around the implants over 12 months. This randomized, controlled clinical trial uses a blinded approach to monitor and compare the two surgical techniques. One group will receive implants using the transcrestal approach with osseodensification burs, which prepare the bone using a special counterclockwise drilling method combined with synthetic bone materials. The other group will receive implants installed with the lateral window technique, where a window is made in the sinus wall, filled with similar synthetic biomaterial, and covered with a membrane. Both groups receive simultaneous implant placement during their respective sinus lift procedures. Participants will report pain levels daily for two weeks after surgery using a visual scale, and track medication use. Post-treatment, cone beam tomography scans will measure bone levels around the implant immediately after prosthetic rehabilitation and again at six and twelve months. Patient quality of life factors such as social and professional isolation, physical appearance, speech, eating habits, and sleep will be assessed through questionnaires during the initial two weeks. Data analysis will compare outcomes between the two techniques over time.
