Abstract: FIXED DENTURES (Abstract).Aim of this study was to evaluate the clinical and radiological status of the peri -implant tissues in patients treated with posterior implant-supported partial fixed dentures. Materials and methods:The retrospective research was conducted on a cohort of 48 patients (mean age 63.04 ± 10.723 years).The study group included patients with posterior edentulism treated by i mplant-supported metal-ceramic fixed prosthetic restorations.Socio-demographic data (gender, age group) and anamnestic data were collected on: smoking status; periodontal grade; compliance to the supportive periodontal/peri-implant therapy; OHI index.Clinical and radiological parameters were assessed for 166 implants to establish the status of the peri -implant tissues and prevalence of peri-implantitis.Results: 45.8% of patients and 19,9% of implants were diagnosed with peri-implantitis.Significant statistical differences were found between implants without peri-implantitis and implants with peri-implantitis for gender (p= 0.022 * ), age group (p= 0.018 * ), smoking status (p= 0.007 ** ), OHI index (p < 0.001 ** ), periodontitis stage (p < 0.001 ** ), and compliance to periodontal/peri-implant support therapy (p<0.001* ).Conclusions: Although peri-implantitis affects almost half of the patients (45.8%), the proportion of individual implants affected is lower (19.9%).Incidence of peri -implantitis was significantly lower to patients with good oral hygiene, non-smokers, low grade periodontal disease, or patients compliant with periodontal/peri-implant support therapy.
