Implant placement and immediate loading in maxillary posterior has always been a challenge because of various conditions like less dense bone, etc. Osseodensification has proven to be a superior technique to improve the overall success rate of implant restorations. This study is done on 28 patients with maxillary posterior missing tooth (n=14 each). The implant stability (using RFA method) and crestal bone levels are evaluated at the time of implant loading and at the end of 3 months. Osseodensification technique turns out to be the superior osteotomy preparation technique than conventional one in terms of stability and crestal bone loss in immediately loaded dental implants placed in maxillary posterior region.
