Clinical Behavior of Dental Restorations Made with Compomers, Comparing with Composite and Glass Ionomers

Abstract

Compomers have emerged by modifying dental composites in an effort to combine their desired properties, namely their good aesthetics, with those of glass ionomer cements, namely their ability to release fluoride for a long time. While this combination of good aesthetics and fluoride release may seem to give compomers an advantage, their poor mechanical properties limit their use. The main components of the compomers are polymerizable dimethacrylate resins, such as urethane dimetha-crylate and TCB (a butantetracarboxylic acid reaction product) and hydroxyethyl methacrylate and ionizable glass fillers, such as fluorosilicate glass.
