Estado de las prótesis fijas cementadas en la clínica odontológica UCSG semestre A-B 2017.

Abstract

Introduction: There are different prosthetic treatments, which aim to restore and reconstruct dental structure, in addition to returning the function, health and aesthetics that have been lost due to the presence of caries or dental trauma, one of the treatments mostly used is the fixed prosthesis. These prosthetic treatments must meet certain clinical and radiographic characteristics to determine their longevity; these are a correct marginal adjustment, the absence of secondary or recurrent caries, periodontal health and the appropriate adjustment of the interproximal contact points. Objective: To evaluate the status of cemented fixed prostheses in the dental clinic of the UCSG semester A-B 2017, through a clinical and radiographic inspection. Materials and methods: Cross-sectional and observational descriptive study, 92 fixed prostheses were evaluated, between crowns and bridges in the Dental Clinic of the Catholic University of Santiago de Guayaquil, respecting the inclusion criteria, to which a clinical and radiographic inspection was performed for the identification of the material, evaluation of marginal sealing, periodontal status, secondary caries and contact points. Results: After the clinical and radiographic evaluation, the incidence of the type of material was 79% for ceramic metal, 17% zirconium and 2% lithium disilicate, the marginal seal had optimal results with 37%, indicating that there was no retention of the Periodontal probe and 14% where if there was a gap with exposure of dentin or cement, in terms of periodontal status, favorable results were obtained with an excellent 35%, no secondary caries was evident and finally, the contact points with 67% Excellent. Conclusion: To achieve the longevity and long-term success of fixed prostheses, these must comply with fundamental characteristics such as adequate marginal sealing, normal periodontal state, correct adjustment of interproximal contact points, in this way we will avoid microfiltration and formation of secondary carious.
