Dental implants are considered the first choice to replace lost or non-restorable teeth. However, posterior maxilla remains a challenge in its management because of the quality of bone in the posterior maxilla.Osseodensification (OD) concept has been proposed in the literature in order to improve primary implant stability, which is an important aspect for osseointegration.Densah bur is novel drills specially designed to enhance bone density by Osseodensification, which in turn increases primary stability.This present study was conducted to assess the use of densah bur as a drilling technique in comparison to the use of standard drilling in implant placement. This was a randomized controlled clinical trial conducted on 20 patients to evaluate available crestal bone height loss and implant stability after implant placement in healed posterior maxillary alveolar ridge.All patients were recalled 2 days after the operation, then weekly for one month, then monthly until the prosthetic phase (6 month postoperative).The clinical evaluation included assessment of post-operative sequelae including edema, pain and postoperative healing. Radiographic evaluation involved cone beam CT radiographs taken for every patient 1week and 6 months postoperatively to evaluate crestal bone height loss. While implant stability quotient was obtained by taking osstell readings using osstel device immediately after implant insertion and 6 months postoperative at time of implant of exposure
