Resin-based cements are dental materials used to bond restorations, such as crowns and bridges, to teeth. They are made from a mixture of resin and filler particles, providing strong adhesion and durability. These cements can be light-cured, meaning they harden when exposed to a special light, or self-curing, which hardens through a chemical reaction. These cements are favored for their aesthetic qualities, as they can be matched to the color of natural teeth. Additionally, resin-based cements offer excellent resistance to moisture and temperature changes, making them suitable for various dental applications, including orthodontics and prosthodontics.
