Resumen

Múltiples son los factores que pueden desencadenar fracturas de porcelana en una prótesis parcial fija metal-cerámica, aunque esta situación no siempre determina un reemplazo. La reparación de porcelana mediante el uso de resina compuesta es una alternativa con ventajas de una fácil manipulación y bajo costo. El objetivo del presente artículo es presentar a la resina compuesta como una opción con resultados considerables en la reparación de prótesis metal-cerámicas fracturadas, con alto compromiso estético. Se presenta un caso clínico de reparación intraoral de una prótesis fija metal-cerámica de seis unidades en el sector anterior superior. El tratamiento realizado incluyó fresado de la superficie de porcelana, aislamiento absoluto, grabado ácido con fluoruro de fosfato acidulado, microarenado con óxido de aluminio, silanización, aplicación del adhesivo convencional y tres tipos de resinas compuestas, resina opaca, microhíbrida y resina de nanorelleno. A los 8 meses se evaluó la adaptación de la reparación mediante un explorador e inspección visual, secando con una jeringa triple donde no se observó signos de percolación alguna. Basado en los resultados se puede considerar a esta combinación de resinas compuestas como una alternativa útil en la reparación de porcelana fracturada.

Abstract

There are multiple factors that can trigger a fracture of porcelain in a metal-ceramic fixed partial denture, although a replacement is not always required. The porcelain repair using composite resin is an alternative with advantages such as easy handling and low cost. The aim of this paper is to present the composite as an option with significant results in the repair of fractured metal-ceramic prostheses, with a high aesthetic commitment. We report a case of intraoral repair of a six-unit metal-ceramic fixed prosthesis in the anterior superior sector. The treatment provided included milling of the surface of porcelain, absolute isolation, acid etching with acidulated phosphate fluoride, aluminium oxide sandblasting, silanization, conventional adhesive application and three types of composite resins: opaque resin, micro-hybrid resin and nanofilled resin. After 8 months we assessed the adaptation of the repair using a surface explorer and visual inspection, drying with a triple syringe. No signs of seepage were observed. Based on the results, this combination of composite resins can be considered as a useful alternative in the repair of broken porcelain.
