| Popis: | Objective The objective of this four-year cohort prospective study was to evaluate the effect of inadequate access to peri-implant hygiene on marginal bone level (MBL). Material and methods Forty-one partially edentulous patients (16 males and 25 females, aged 49.8 ± 11.9 years) who had implants with at least one year in function were selected. Patients were clinically and radiographically evaluated at three different times: baseline (T0), 2-year (T1), and 4-year (T2) follow-up intervals. At baseline, implants were classified and allocated into two groups: those presenting adequate access (ACC) and inadequate access (no-ACC) to peri-implant hygiene. A linear mixed-effects model for clustered longitudinal data was used to analyze MBL, probing depth (PD), plaque index (PI), and bleeding on probing (BoP). Results Of 131 implants, 74 were considered as having ACC, and 57 as having no-ACC at T0. Implants in the no-ACC group presented a statistically greater mean MBL measurement at T2 than implants in the ACC group (p = .011). In the no-ACC group, a significant reduction in PD from T0 to T1 (p = .019) and from T0 to T2 (p = .010) was observed. Regardless of the group, PI significantly increased at both T1 (p = .00001) and T2 (p = .00004). Regardless of time, the prevalence of BoP was significantly higher in the no-ACC group than in the ACC group (p = .012). Conclusion Inadequate access to peri-implant hygiene frequently resulted in more peri-implant inflammation and MBL over time. Proper accessibility to peri-implant hygiene should be carefully considered during planning of implant restoration, and patients properly motivated into maintenance care. |
