Composite
Free!
Composite is a tooth-colored dental resin used to restore cavities, repair chips, and enhance smiles. It bonds to enamel and dentin, offering strong, durable, and natural-looking results. Available in flowable and sculptable forms, it suits both front and back teeth. With excellent polishability and shade options, composite is preferred for aesthetic, minimally invasive restorations in everyday dentistry.
Description
Composite, commonly known as dental composite resin, is a tooth-colored restorative material used to repair cavities, fractures, and aesthetic defects. It is a blend of resin matrix and inorganic filler particles, designed to mimic the translucency and shade of natural teeth. Available in flowable and packable forms, it offers excellent handling, polishing characteristics, and adhesion when used with proper bonding agents. Composites are light-cured, allowing controlled working time and precise sculpting before setting.
Key features and benefits:
• Highly aesthetic with multiple shades for natural blending
• Strong mechanical properties suitable for anterior and posterior restorations
• Bonds micromechanically to enamel and dentin using adhesive systems
• Polishable to a glossy finish for long-term esthetics
• Available in flowable versions for base layers, liners, and small cavities
• Radiopaque formulations allow clear visibility on radiographs
Typical uses and clinical applications:
• Class I, II, III, IV, and V cavity restorations
• Diastema closure, enamel defects, and cosmetic reshaping
• Core build-ups for crowns in low-stress areas
• Repairing porcelain or existing composite restorations
• Pediatric and minimally invasive dentistry
How it compares:
• Versus amalgam: offers superior esthetics and requires less tooth reduction
• Versus glass ionomer: provides greater strength and polish retention, though without continuous fluoride release
• Versus compomer: typically stronger and more polishable for long-term restorations
Handling and quality considerations:
• Light-curing requires incremental layering to control shrinkage and achieve depth of cure
• Manufacturers often follow ISO standards for biocompatibility and compressive strength
• Proper finishing and polishing enhance longevity and stain resistance
Composite brings the ideal balance of strength, beauty, and versatility, making it the material of choice for modern restorative and cosmetic dentistry.
