Basic and Clinical Research

Objective: This study was performed to evaluate the performance of a contemporary dental implant. Assessments were made regarding implant survival and radiographic bone changes from surgical placement to subsequent time points.

Materials and Methods: Seventy-five patients received 204 dental implants. One hundred and seventy-six implants were placed into healed ridges and 28 implants were inserted into fresh extraction sockets. Implant survival percentages and mean data pertaining to radiographic proximal bone loss for 1 randomly selected implant per patient are presented.

Results: The survival rates for implants placed into healed ridges and fresh extraction sockets were 98.6% and 96.4%, respectively. The overall survival rate for all implants in the 75 patients was 99.0%. With respect to proximal bone levels, mesial and distal bone loss from surgical placement to 12 months was 0.96 mm mesially and 0.83 mm distally. From 24 to 36 months follow-up, the mesial and distal bone changes were 0.16 mm and 0.19 mm, respectively. Up to 36 months after implants were placed into fresh extraction sockets, the mean distance from the implant-abutment interface to the first bone to implant contact was 1.01 mm mesially and 1.10 mm distally.

Conclusion: With respect to the time frame of the study, assessed parameters were similar to other implant systems that are currently used.
