Abstract

Implant therapy has become a widely recognizedtreatment alternative for replacing missing teeth. Several long term follow-upstudies have shown that the survival rate is high. However, complications mayappear and risk indcators associated with early and late failures have beenidentified. The purpose of the present retrospective clinical study was todescribe some clinical features of patients with clinical signs ofperi-implantitis and to identify risk indicators of peri-implantitis in apopulation at a specialist clinic of Periodontology. In total,the materialconsisted of 377 implants in 111 patients with thediagnosis peri-implantitis. The mean age at the examination was found to be56.3 years (range 22-83) for females and 64.1 years (range 27-85) for males.The mean number of remaining teeth was found to be 10.5 (S.D. 8.89) and themean number of implants was 5.85 (S.D. 3.42). Fora majority of the subjects, more than 50% of the remaining teeth had a marginalbone loss of more than 1/3 of the root length. Forty-sex percent of thepatients visited regularly dental hygienists for supportive treatment. Thepercentage of implants with peri-implantitis wassignificantly increased for smokers compared to non-smokers (p = 0.04). In thegroup of non-smokers, 64% of the implants had thediagnosis peri-implantitis, while the corresponding relative frequency forsmokers was 78%. A majority of the individuals had a Plaque index and Bleedingon probing index >50%. The median of the follow-up time after implantplacement was 7.4 years and the observation period was not significantlycorrelated to the degree of bone loss around the implants.Among the subjects with a mean bone loss >6 mm at implantswith peri-implantitis, more than 70% had a mean marginal bone loss > 1/3 ofthe root length of the remaining teeth. A positive and significant correlationwas found between the degree of marginal bone loss in remaining teeth and thedegree of bone loss around implants withperi-implantitis. In conclusion, the results of the present study indicate thatsmoking as well as previous history of periodontitis are associated withperi-implantitis and may represent risk factors for this disease
