Composite material is primarily comprised of which components?

  1. Filler particles and metals

  2. Composite and resins

  3. Synthetic resins and filler particles

  4. Glass and epoxy resins

The correct answer is: Synthetic resins and filler particles

Composite materials used in dentistry, particularly in the context of dental restorations and fillings, are mainly made up of two critical components: synthetic resins and filler particles. The synthetic resin serves as the matrix that binds the material together, providing the necessary strength and stability. Filler particles, which are typically made from materials like glass, silica, or quartz, are added to enhance the properties of the composite. They improve the material's strength, durability, and wear resistance, making it suitable for use in restorative procedures. The combination of synthetic resins and filler particles allows for a material that can closely mimic the appearance of natural tooth enamel, as well as providing the required mechanical properties to withstand the forces of mastication. This effective blend results in a versatile and widely used material in modern restorative dentistry.
