Context: Dental implantology is the state of the art technique to replace missing teeth. Crestal bone loss along implant surface jeopardizes its longevity and success of treatment. Aims: This study evaluates the implant stability and the crestal bone loss along the implant surface six months after the implant placement, but before prosthetically loading it. Materials and Methods: 100 two-stage implants were placed in 56 patients. Digital OPG was taken on the day of implant placement. After six months, at the time of second stage surgery, the implant stability was evaluated by the Periotest instrument. The crestal bone loss on the mesial and distal side of the implant was evaluated on digital OPG. Results: Six months after the implant placement, Periotest evaluation showed a mean of 1.9, which indicated that implants were well osseointegrated and stable. Radiographic evaluation on digital OPG showed a mean crestal bone loss of 0.6mm on the mesial side of implant and 0.9 mm on distal side of implant. Conclusions: Even before prosthetically loading the two-stage implant, crestal bone loss of 0.6 to 0.9mm occurred around the implant. The smooth polished collar design of the implant may have contributed to crestal bone loss.
