Abstract
BackgroundPeri-implant marginal bone-level (MBL) alteration represents one of the parameters included in the criteria for determining implant health. ObjectiveFactors affecting peri-implant MBL alteration for 4-implant-supported fixed mandibular prostheses (4-ISFMP) were assessed. Material & MethodsA 3-year prospective, cohort study was conducted on 44 mandibularly edentulous patients treated with 4-ISFMP. Peri-implant MBL alteration was evaluated radiographically at the 12-, 24- and 36-month follow-ups considering to patient-related risk factors [age, gender, diabetes mellitus, smoking, cardiovascular disease (CVD), rheumatic disorders (RD)] and implant/prosthesis-related features (implant location, keratinized gingiva, denture cantilever length, prosthesis supporting zone, opposing dentition) as well as to peri-implant biological parameters (plaque-, bleeding-, calculus index). Results148/176 implants (37 patients, drop-out: 15%) were followed for 3years showing significant (p<0.001) annual differences of MBL alterations over time. The univariate analysis demonstrated differences of MBL alterations for smokers (p=0.014), for patients with CVD (p=0.001) and RD (p=0.011). In the 3-year multivariate analysis, MBL alteration was influenced by time (p<0.001) and showed relationship with risk factors as smoking (p<0.002;OR=18.965), CVD (p<0.021;OR=5.172), RD (p<0.006;OR=50.171) and plaque-index (p=0.034;OR=3.252). ConclusionsAlthough peri-implant MBL alteration increased annually, significant odds ratios, were found for patients-related risk factors identifying them potentiating the alterations.
