Which type of composite is recommended for use in load-bearing areas?

Hybrid composites are recommended for use in load-bearing areas due to their balanced properties, which combine strength and aesthetics. These materials typically have a combination of both larger and smaller filler particles. The larger particles offer increased strength and wear resistance, making them suitable for areas subjected to significant forces during function, such as posterior teeth.

In contrast, other composite types may not provide the same level of durability or strength needed for these areas. Micro-filled composites, for instance, are known for their excellent polishability and aesthetic qualities, but their mechanical strength is usually lower, making them less suitable for load-bearing situations. Flowable composites, while useful for their adaptability and ease of placement in small spaces, often have lower filler content and, consequently, reduced strength and wear resistance. Nanohybrid composites, although strong and versatile, may not have the same track record as hybrid composites specifically in high-stress areas, making hybrids the preferred choice for load-bearing applications.
