Background: ￼To evaluate the incidence and risk factors in well-maintained subjects with dental implants with bioceramic molecular impregnated treatment (Ossean®, Intra-Lock International, Boca Raton, FL, USA) in function in a 5-year period. Aim/Hypotesis: Peri-implantitis is a plaque-induced inflammatory reaction characterized by presence of probing pocket depth and bone loss. There are several implant surface topographies available in the market as well as some hypothesis that showed specific surface topographies can be more susceptible than other. Matherials and Methods: Two hundred and sixty-eight implants of 3.3-5.0 mm width and 8-13mm length were installed in 89 subjects between 2010 and 2011. Implants were functionally loaded after 60-day post-surgery with a provisional restoration and thereafter final restorations in ceramic were delivered. Radiographic bone loss was measured on periapical radiographs after 4, 12, and 60 months. Periodontal parameters as percentage of visible plaque, marginal bleeding, probing depth, clinical attachment level, bleeding on probing and suppuration were also evaluated at 60 months. Technical problems as ceramic fracture and loose of abutment screw were evaluated. The cumulative survival and implant-restoration success were assessed using the Kaplan-Meier survival estimator; Chi-square test was applied to evaluate correlations between the study variables. Results: The mean of radiographical bone loss after 60 months was 1.03mm (± 0.30). Six dental implants were lost due to Peri-implantitis (PD >5mm; BoP and/or sup; Bone loss >4mm); 4 out 6 dental implants were lost in smokers with history of periodontitis. A total of 11 dental implants were lost after 5y - 95.89% of success rate. Incidence of peri-implantitis was 2.23% and mucositis 24.35% (PD>4mm, BoP and no bone loss). However, 4.30% of the remaining implants present risk for peri-implantitis (bone loss >3mm without BoP). Lower incidences of technical problems during the period of evaluation at 5 years were observed (11.23%). Conclusions and Clinical Implications: Within the limitation of this prospective study, dental implants with bioceramic molecular impregnated treatment placed in a well-maintained patient presented higher success rate and low incidence of peri-implant diseases after 5y follow-up.
