A retrospective radiographic study was conducted from five private dental offices on patients requesting dental implant therapy to replace their missing teeth. All implants were placed and restored by early 2000, and patients were encouraged to continue their dental care at the same office. The records were reviewed and analyzed by the clinicians, who had more than 15 years of dental experience at the time of the initial patient treatment. A total of 74 patients with 242 implants were recalled up to 10 years (mean follow-up: 9.21 ± 1.7 years) after loading. There were five implant failures from this radiographic observation period, resulting in a 97.9% dental implant survival rate. The mean crestal bone level change on the mesial aspect was –0.36 ± 1.05 mm, while the mean crestal bone level change on the distal aspect was –0.18 ± 0.96 mm. Thus, the overall mean bone loss was –0.28 ± 0.05 mm. The dental implants, which had a sandblasted, large-grit, acid-etched surface, appeared to achieve successful osseointegration in this long-term observation period, and the implant system’s unique design and surface features resulted in a stable osseous crest without bone loss to the first thread.
