Pathologies in peri-implant tissues are common and may disturb long-term implant supported rehabilitation. We aimed to evaluate the occurrence of such peri-implant diseases and their associated factors in this study. Peri-implantitis and mucositis were diagnosed based on clinical and radiological findings. Statistical analysis was performed with the X2 and logistic regression. Peri-implant mucositis and peri-implantitis were observed in 43.4% and 13.8% of patients with implants evaluated, respectively. Univariate analysis found associations with systemic changes (p=0.016; yes), medication use (p=0.010; yes), implant location (p<0.0001; upper jaw), implant region (p=0.008; posterior), previous augmentation procedure (p=0.023; yes), time of prostheses use (p<0.0001; >2 years), keratinized mucosa (p<0.0001; absence) and gingival bleeding index (p=0.005; >30%). In the multiple analysis, independent predictors were: >2 years of prostheses use (p<0.0001; PR=1.720), upper jaw location (p<0.0001; PR=1.421), gingival bleeding index >30% (p=0.001; PR=1.496), and use of medication (p<0.0001; PR=1.261). The frequency of peri-implant pathologies is high (approximately 57.2%) with several aspects of the occurrence being related to the patients’ prosthesis. Prostheses type and the complexity of rehabilitation are worth highlighting. Factors include the location of the dental implant, gingival bleeding index, patient's use of medication(s), and the time of prostheses use.
