Prevalence and risk indicators of peri-implantitis after 8 to 10 years of function

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.

Prevalência Das Doenças Peri-Implantares Em Pacientes Portadores De Próteses Totais Fixas Sobre Implantes

“…Já no caso da mucosite, a média ponderada baseada em implante e em paciente foi de 29,48% e 46,83%, respectivamente, ressaltando a necessidade de uma maior atenção a esse problema. No presente estudo, 32,2% dos implantes estavam com MPI e 13,3% com peri-implantite 10 .…”

“…Quando avaliada a prevalência das DPIs em relação ao paciente, dos 29 examinados apenas 8 (27,6%) tinham todos os implantes saudáveis (sem doença periimplantar), 37,9% (11) apresentaram MPI e 34,5% dos examinados (10) peri-implantite em pelo menos um dos seus implantes, considerando sempre o quadro mais avançado, ou seja, caso o paciente apresentasse alguns implantes saudáveis e outros doentes, seria definido o diagnóstico a partir da doença mais grave.…”
