Dental Composites — Mechanical Stability
In dental applications, light-curing dental composites are used as restoratives (fillings) or veneering materials.
The materials are generally composed of methacrylate systems such as bis-glycol-dimethacrylate (bis-GMA) or urethane dimethacrylate (UDMA). Additional monomers are used as diluent or to guarantee the cross-linking abilities of the resin. Inorganic fillers up to 80 weight percent improve the mechanical properties and reduce shrinkage during cross-linking. (measurement with Photo-DSC 204 F1 Phoenix®®).
