Fillers play a crucial role in composite resins used in dentistry, as they help to enhance the physical, mechanical, and aesthetic properties of the material. Some of the key roles of fillers in composite resins include:
Reinforcement: Fillers are added to composite resins to provide reinforcement and improve the strength and durability of the material. The fillers Modulus of elasticity more with the its stress under resistance: Fillins, making them more durable and long-lasting in the oral cavity.
Aesthetics: Fillers can be used to match the color and translucency of the natural tooth structure, ensuring that the dental restoration blends seamlessly with the surrounding teeth.
Thermal expansion coefficient: Fillers can help reduce the thermal expansion coefficient of the composite resin, minimizing the risk of marginal leakage and secondary caries.
Overall, fillers play a crucial role in enhancing the physical, mechanical, and aesthetic properties of composite resins, making them versatile and effective for dental restorations.
