What this Trial Is About
Researchers are evaluating two different techniques for ridge splitting with simultaneous implants in the posterior mandible to assess bone augmentation. This randomized clinical trial compares the conventional method using bone discs with a study method using piezo surgery bone inserts. Participants include patients with specific bone height and width criteria and single missing teeth or previous failed implants, aiming to improve bone quantity and implant stability. Both groups undergo preoperative CBCT scans and receive local anesthesia during the procedure. The surgical process involves creating a full thickness mucoperiosteal flap and performing crestal osteotomy and semi-vertical osteotomies using either piezo surgery inserts or bone discs. Implants are placed submerged below the alveolar crest, followed by bone smoothing, application of xenogenic bone particles, and tension-free flap closure with sutures. Postoperative CBCT is performed at four months to evaluate bone gain. Participants will be assessed through imaging and clinical evaluations including CBCT scans before and four months after surgery, as well as soft tissue examination at baseline and one week post-operation. The primary measurement is the amount of bone gained at four months after ridge augmentation. Researchers will monitor soft tissue healing and ensure proper flap closure. Participants' involvement spans from preoperative testing through multiple follow-up assessments over several months.
