Objetivo: Esse estudo teve como objetivo avaliar a prevalência de mucosite (Mi) e peri-implantite (Pi) em pacientes com sintomas relacionados à Pi e Mi, tratados com próteses implanto-suportadas e verificar sua associação com fatores locais, sistêmicos e ambientais. Método: Quarenta e três pacientes com 150 implantes reabilitados com próteses implanto-suportadas, por ao menos 5 anos, com sintomas relacionados a doença peri-implantar foram recrutados para exames clínicos e radiográficos. Características das próteses implanto-suportadas, hábito de fumar, aspectos da saúde geral, periodontal e peri-implantar foram coletados para verificar a prevalência da doença peri-implantar e sua associação com fatores locais, sistêmicos e ambientais. Resultados: A média de idade dos pacientes foi de 58.81 (33-74), entre esses 20 eram mulheres e 23 homens. Peri-implantite e mucosite foram diagnosticados em 31 (72%) e 12 (28%) pacientes, respectivamente. A prevalência de peri-implantite e mucosite baseada no implante foi 90 (58,44%) e 60 (38,96%), respectivamente. Diabetes foi associada a periimplantite a uma taxa de OR = 10,01 (p=0,002). Próteses fixas de arco total (PFAT) e parciais fixas (PPF) foram associadas a Pi a uma razão de OR = 10,01 e 9,36 (p=0,002), respectivamente. Conexões hexágono interno (HI) e externo (HE) foram associadas a Pi a uma taxa de OR = 8,80 (p=0,003) e 9,35 (p=0,002), respectivamente. Profundidade de sulco peri-implantar (PS) 6 mm foi associada a presença de defeito vertical a uma razão de OR = 1,09 (p=0,003). Presença de mais de um implante por paciente e diabetes foi associada a uma taxa de OR = 7,72 (p=0,005). Conclusão: Pacientes com sintomas relacionados a Pi e Mi apresentaram uma alta prevalência de doença peri-implantar. Diabetes, PFAT, PPF, conexões HI e HE foram associadas a uma maior chance de apresentar Pi. PS 6 mm foi associado a presença de defeito ósseo vertical. Pacientes diabéticos com mais de um implante apresentaram maior chance de Pi.

Aim: The objective of this cross-sectional study was to evaluate the prevalence of mucositis (Mi) and peri-implantitis (Pi) in patients complaining of symptoms related to Pi and Mi, treated with implant-supported prosthesis and assess its association with local, systemic and environmental factors. Methods: Forty-three patients with 150 implants restored with implant-supported prosthesis, for at least 5 years, and complaining of symptoms related to peri-implant disease were recruited for clinical and radiographic examination. Implant-supported prosthesis characteristics, smoking habits, general, periodontal and peri-implant health status were assessed to establish the prevalence of peri-implant disease and its association with local, systemic and environmental factors. Results: Mean patient age was 58.81 (33-74), among which 20 were female and 23 were male. Periimplantitis and mucositis were diagnosed in 31 (72%) and 12 (28%) patients, respectively. Implant-based prevalence of peri-implantitis and mucositis amounted to 90 (58.44%) and 60 (38.96%), respectively. Diabetes was associated with peri-implantitis at an odds ratio of OR = 10.01 (p=0.002). Full-arch (FAFP) and partial (PFP) implant-supported fixed prosthesis were associated with Pi at an odds ratio of OR = 10.01 and 9.36 (p=0.002), respectively. Internal (IH) and external hexagon (EH) abutment was associated with Pi at an odds ratio of OR = 8.80 (p=0.003) and 9.35 (p=0.002), respectively. Peri-implant pocket-probing depth (PD) 6 mm was associated with the presence of vertical bone defect at an odds ratio of OR = 1.09 (p=0.003). Presence of more than one implant per patient and diabetes was associated with an odds ratio of OR = 7.72 (p=0.005). Conclusion: Patients complaining of symptoms related to Pi and Mi showed a high prevalence of periimplant disease. Diabetes, FAFP, PFP, IH and EH abutment was associated with higher chance of Pi occurrence. PPD 6 mm was associated with the presence of vertical bone defect. Diabetic patients with more than on implant showed a higher chance of Pi occurrence.
