Aim: The aims of the present study were to retrospectively examine Norwegian patients with osteogenesis imperfecta (OI) and dental implants, and to prospectively study a group of patients with OI in need of such treatment. Our hypothesis was that implant treatment in these patients has approximately the same success rate as in healthy persons. Study group: Seven patients with a diagnosis of OI and a total of 26 dental implants were invited to participate in the retrospective study. The prospective part of the study included a total of 20 implants in seven patients. Results: The patients in the retrospective study were seen after an average of 74 months after loading, range 25–135 months. Two implants had been lost, both of them before prosthetic loading and in the same patient. Bone loss of 4 mm or more was seen around three implants in two patients. The patients in the prospective study were followed for a mean observation time of 20 months after loading, range 12–33 months. No implants were lost in that group, and only minimal bone loss was observed (less than 1 mm around two implants in one patient). Conclusion: In these OI patients, the total implant survival rate was 95.7%, being 93.3% in the retrospective group and 100% in the prospective group, respectively. |
