Avaliação radiográfica da remodelação óssea peri-implantar em implantes com diferentes conexões e componentes protéticos: um estudo clínico, randomizado e controlado de boca dividida

Abstract

Currently, it is believed that prosthetic components smaller in diameter than the implant platform (switching platform) use periimplant bone remodeling compared to those with the same platforms (corresponding platform), those using the type of implant used. in rehabilitation. In this sense, the present work allows the verification of the alteration of the prosthetic platform and the profile of the prosthetic component that influences the periimplant bone remodeling process. This is a randomized, split-mouth controlled clinical study conducted at the Dental Clinic of the Faculty of Dentistry-FJF approved by the Research Ethics Committee of the same institution under Opinion No. 2,424,701. 48 implants were installed, 24 external hexagons and 24 more cone. These were randomized and rehabilitated with Switching and Matched platform. Radiographic follow-up (t1 and t2) was performed and the mesial (REMO VM) and distal (REMO VD) vertical removal was removed in 4 study groups (CMS, CMM, HES, HEM) after crown installation (t1) and after 90 days (t2). For measure REMO V.M. or p-value obtained for the measure was 0.822 and for the measure REMO V.D. was 0.729. At the 5% significance level, we can say that there was no difference between the groups for the data collected from bone remodeling. When analyzing within the same group (t2-t1) only the HEM Group measured REMO V.D. presented average difference between the beginning and the 90 days of treatment. At the beginning of treatment, the average was 1.048 and the 90-day average was 1.235, perceived as a significant increase in the mean, ie, there was greater bone remodeling during implantation in this group. Within the limits of this study, we can conclude that periimplant vertical bone remodeling requires clinical follow-up time to be evaluated because they are time-dependent multifactorial causes. There were no results selected when comparing platform and pillar combinations during the period evaluated. A combination between HEM REMO V.D. was, within the follow-up time, the only combination showing significant bone remodeling.
