COMPARISON OF IMPLANTOPLASTY AND THE MECHANICAL DEBRIDEMENT ON THE SURGICAL TREATMENT OF PERIIMPLANTITIS
Periimplantitis; Therapeutics; Dental Implantation.
Periimplantitis is considered a progressive and irreversible disease around dental implants, involving soft tissues damage and bone resorption. Surgical therapy has been pointed as the main strategy for the treatment of peri-implantitis that combines the concepts of the non-surgical therapy with resective and / or regenerative procedures. The study aimed to evaluate the effect of the surgical therapy comparing the implantoplasty with the mechanical debridement in the treatment of peri-implantitis. It is a prospective, controlled, randomized and double-blinded clinical trial. Subjects were randomly allocated into two groups: surgical access + basic therapy (control group I) and surgical access + basic therapy + implantoplasty (test group-II). The clinical parameters evaluated were the plaque visible index (VPI), gingival bleeding index (GBI), probing depth (PD), bone level (BL), bleeding on probing (BOP); as well as the assessment of of quality of life by the Oral Health Impact Profile (OHIP-14). Subgingival biofilm samples were also collected for microbiological analysis and salivary fluid for analysis of oxidative stress markers. The preliminary results show that of the 9 treated participants, 77.8% are female, with an average age of 61.3 years. From the 21 implants treated, 13 were in therapy I and 8 in therapy II. From all rehabilitations, 66.6% were full dentures, 22.2% were partial and 11.1% were single. For statistical analysis, Wilcoxon test was used with a 5% significance level. There was a statistically significant reduction in VPI (76% to 58%) in the test group and in GBI (66% to 33 %%) in the control group, at 3 months. However, there were no significant differences within groups in relation to PD when they were compared in each period, nor when comparing each intervention group.
