Indirect Composite Resins: Material Aspects

Indirect composite resins are dental restorative materials, similar to regular composite resins, but fabricated outside the mouth in a laboratory setting, allowing for greater control over the restoration's shape and strength, typically used for larger tooth restorations like inlays, onlays, and overlays. These materials undergo additional curing with heat, light, and pressure, leading to enhanced physical properties like strength, wear resistance, and color stability. Thus, offering improved aesthetics and mechanical properties compared to direct composite fillings due to their higher filler content and controlled polymerization process; the key advantage being reduced polymerization shrinkage stress because the curing occurs in a thin layer of cement on the tooth rather than within the entire restoration itself.
