Reabilitação de selas livres com prótese removível

: caracterização e resolução de complicações

Abstract

Introduction: the oral rehabilitation with removable partial prosthesis plays a very important role in the restoration of the main functions of the stomatognathic system due to the prevalence of partial edentulism in an increasingly aging population. In this perspective it is important to know and to characterize the main complications associated with the use of removable partial dentures in order to contribute to the optimization of their resolution. Objectives: To identify and characterize the existing failures in removable partial prosthesis in Kennedy’s class I and II type edentulism, as well as the process of resolving them. Materials and Methods: This study was a retrospective longitudinal observational study type. It was performed a survey of rehabilitated patients with removable partial dentures in Kennedy’s class I and II type edentulism in the University Clinic of Portuguese Catholic University, since the year 2011. For that it was used the clinical management program called NewSoft®, as well as the paper records of Removable Prosthodontics Subject Area. It was also requested to attend the patients in control visits for data update and registration of any changes in its prosthetic rehabilitation. After complications characterization and their resolution it was analysed a relationship with: gender, age, year of RPD placement, RPD location and type of edentulism based on Kennedy‘s classification. It was also compared the presence / identification of systemic pathology with relevance in bone metabolism with the need for saddles relining. The collected data was processed and subjected to statistical analysis using the IBM SPSS Statistics program, v21.0.0 (Software Statistical Package for the Social Sciences). Results: The most observed biological complication was periodontal disease in abutment teeth; on the other hand, the more common mechanical complication was the need for saddles relining; into the comparative analysis, there was no significant dependence relationship between any of the variables discussed; in other words in parameters such as gender, age, year of RPD placement, RPD location and type of edentulism (based on Kennedy) it wasn’t found a significant relationship with any of prosthetic complications addressed. Conclusions: According to this study, there was no significant relationship between gender, age, year of placement of PPR, the PPR location and type of edentulous (based on Kennedy) and each of the prosthetic complications addressed, whether biological or mechanical. Therefore it is required further studies with a larger sample size, a bigger follow-up time and participants rehabilitated in others dental university clinics and/or private clinics.
