Composite Resin
A tooth-colored restorative material composed of a resin matrix (typically bis-GMA) reinforced with inorganic filler particles, used for direct dental restorations.
Full Definition
Composite resin is a widely used aesthetic restorative material consisting of an organic resin matrix—most commonly bisphenol A-glycidyl methacrylate (bis-GMA)—combined with inorganic filler particles such as silica or glass. It is photopolymerised (light-cured) in clinical settings and bonds to tooth structure via an adhesive bonding agent. Editors should hyphenate 'composite resin' only when used as a compound modifier before a noun (e.g., 'composite-resin restoration'). It should not be abbreviated to 'composite' without prior definition in formal clinical documents. The material is commonly contrasted with amalgam in discussions of aesthetics and biocompatibility.
Usage
Usage note: Hyphenate only as a compound modifier: 'composite-resin restoration' but 'the restoration is made of composite resin'. Do not abbreviate to 'composite' without definition in formal documents.
