Prevalência das doenças peri-implantares e seus indicadores de risco – estudo transversal multicêntrico

Resumo (EN)

Objectives: To determine the prevalence of peri-implant diseases and associate with possible risk indicators and characteristics of implants in partially edentulous patients who received implant-supported rehabilitation. Material and methods: 147 patients with 490 implants who received implant-supported rehabilitation with at least 1 year in function were evaluated by clinical and radiographic evaluations. Factors related to patients and characteristics of implants were evaluated. Statistical analyzes included univariate logistic regression for selection of associated factors and application of multiple logistic regression. The odds ratio and confidence interval (95%) were calculated and the Wald test was used to assess the significance of each coefficient in the multiple model. For the analysis of waste was applied the Hosmer-Lemeshow test. Results: The prevalence of peri-implantitis and peri-implant mucositis in patients were 80.3% and 19.0% and 85.3 implants and 9.2%, respectively. Smokers have 6.87 times more likely (p = 0.018) had mucositis and 5.87 times more likely (p = 0.031) having peri-implantitis. Patients who did not have the support of periodontal therapy had 2,462 (p = 0.039) more likely to have mucositis and 2,428 times more likely (p = 0.049) having peri-implantitis. The type of connection of the implants and the presence of inadequated adapted prosthesis were factors that influenced the occurrence of peri-implant mucositis. As for peri-implantitis, using switching platform was a protective factor, as well as the amount of keratinized mucosa. In the tissue analysis of implants, the type of connection and the presence of inadequated adapted prosthesis were factors that influenced the occurrence of peri-mucositis deploy. As for peri-implantitis use switching platform has a protection factor, as well as the amount of keratinized mucosa. Conclusion: Despite the limitations presented in this study, smoking and periodontal supportive therapy were risk factors associated with peri-implant mucositis and peri-implantitis. As implant characteristics, the type of connection and inadequated adaptation influenced the occurrence of periimplant mucositis and the presence of keratinized mucosa and platform switching system were protective variables to peri-implantitis.
