Composite resins are materials commonly used in dentistry and other fields for their strong, durable, and aesthetic properties. They are made by combining a resin matrix with filler particles, which can include glass or ceramic. This combination enhances the material's strength and improves its appearance, making it suitable for applications like dental fillings and restorations. In addition to dentistry, composite resins are also used in industries such as construction and automotive manufacturing. Their versatility allows them to be molded into various shapes and sizes, making them ideal for creating lightweight yet strong components. This adaptability contributes to their growing popularity in modern engineering and design.
