AIMS/BACKGROUND: The aims of the present study were to evaluate (1) the success rate of unilateral maxillary fixed dental prosthesis (FDPs) on implants in patients at a periodontal clinic referred for periodontal treatment, (2) the prevalence of varying mechanical and biological complications and (3) effects of potential risk factors on the success rate.
MATERIAL AND METHODS: Fifty consecutive patients were invited to participate in a follow-up. The patients had received FDPs on implants between November 2000 and December 2003 after treatment to achieve optimal peridontal health, and the FDPs had been in function for at least 3 years. A questionnaire was sent to the patients before the follow-up examination. Forty-six patients with 116 implants were examined. The follow-up comprised clinical and radiographic examinations and evaluations of treatment outcome.
RESULTS: Before implant treatment, 13% of the teeth were extracted; of these, 80% were extracted due to periodontal disease. No implants had been lost before implant loading. One implant in one patient fractured after 3 years of functional loading and three implants in another patient after 6.5 years. The most frequent mechanical complications were veneer fractures and loose bridge screws. Patients with peri-implant mucositis had significantly more bleeding on probing around teeth and implants. Patients with peri-implantitis at the follow-up had more deep periodontal pockets around their remaining teeth compared with individuals without peri-implantitis, but these differences were not significant. Smokers had significantly fewer teeth, more periodontal pockets ≥ 4mm and a tendency towards greater marginal bone loss at the follow-up, compared with non-smokers.
CONCLUSION: In the short term, overloading and bruxism seem more hazardous for implant treatment, compared with a history of periodontitis.
