Abstract: Introduction: The investigation of peri-implant diseases risk indicators helps to prevent and target treatment techniques.

Objective: The aim of this cross-sectional study was to determine the occurrence of peri-implantitis and its potential risk indicator factors, besides to assess the long-term success and survival rates of dental implants after 8 to 10 years of function.

Material and method: For this, fifty individuals who had received their implant-supported rehabilitation between 2003 and 2005 were included. Data regarding demographics, medical and dental history were collected and a complete clinical examination was performed. Multivariate analysis was used to identify potential risk indicator factors related to the occurrence of peri-implantitis. Overall, 211 implants had been placed; 197 were in function, 9 were still submerged, and 5 had been lost.

Result: Success and survival rates were 81.5% and 97.6%, respectively. Peri-implant mucositis affected 77.1% of subjects and 52.3% of implants. Peri-implantitis was diagnosed in 14 individuals (29.2%) and 25 implants (12.7%). Subjects with osteoporosis (OR = 2.84) and generalized bleeding on probing (OR = 8.03) were significantly associated with higher odds of peri-implantitis. At the implant level, visible plaque (OR = 4.45) and deep probing depths (OR = 4.47) were significantly associated with peri-implantitis.

Conclusion: Through these results, our study suggests that osteoporosis and generalized periodontal/peri-implant mucosa inflammation increase the likelihood of peri-implantitis.

Resumo: Introdução: A investigação dos fatores indicadores de risco para as doenças peri-implantares auxilia na prevenção e direcionamento das técnicas de tratamento

Objetivo: O objetivo deste estudo transversal foi determinar a ocorrência de peri-implantite e seus potenciais fatores indicadores de risco, além de avaliar as taxas de sucesso e sobrevida em longo prazo dos implantes dentários após 8 a 10 anos de função

Material e método: Foram incluídos cinquenta indivíduos que receberam sua reabilitação implanto-suportada entre 2003 e 2005. Dados demográficos, história médica e odontológica foram coletados e um exame clínico completo foi realizado. A análise multivariada foi utilizada para identificar potenciais fatores indicadores de risco relacionados à ocorrência de peri-implantite. Ao todo, 211 implantes foram colocados; 197 estavam em função, 9 ainda estavam submersos e 5 haviam sido perdidos.

Resultado: As taxas de sucesso e sobrevivência foram de 81,5% e 97,6%, respectivamente. A mucosite peri-implantar afetou 77,1% dos indivíduos e 52,3% dos implantes. A peri-implantite foi diagnosticada em 14 indivíduos (29,2%) e 25 implantes (12,7%). Indivíduos com osteoporose (OR = 2,84) e sangramento generalizado à sondagem (OR = 8,03) foram significativamente associados a uma maior chance de peri-implantite. Ao nível do implante, a placa visível (OR = 4,45) e as maiores profundidades de sondagem (OR = 4,47) foram significativamente associadas à peri-implantite.

Conclusão: Por meio desses resultados, nosso estudo sugere que a osteoporose e a inflamação generalizada da mucosa periodontal / peri-implantar aumentam a probabilidade de peri-implantite.
