Composite Resin
A tooth-colored, polymer-based restorative material reinforced with inorganic filler particles, used for direct restorations, bonding, and aesthetic build-ups.
Full Definition
Composite resin is the predominant direct restorative material in modern dentistry, comprising an organic resin matrix (typically bisphenol A-glycidyl methacrylate, or bis-GMA) and inorganic filler particles (silica, zirconia, or barium glass). It is light-cured in situ and bonds micromechanically to tooth structure via an adhesive system. The term appears in operative dentistry reports, insurance treatment codes, material data sheets, and clinical guidelines. Editors should note that 'composite' alone is widely accepted as a shorthand noun and adjective in clinical writing but should be expanded in formal materials science or regulatory contexts.
Usage
Usage note: 'Composite' is acceptable as a standalone noun in clinical records; expand to 'composite resin' in formal regulatory or research documents.
