What is a typical characteristic of porcelain inlays compared to metal inlays?

Porcelain inlays are often characterized by their aesthetic qualities, which make them an attractive option for dental restorations, particularly in visible areas. However, a typical characteristic of porcelain inlays is that they are more prone to chipping compared to metal inlays. This susceptibility arises from the inherent brittleness of porcelain as a material, which can fracture under significant stress or force.

In contrast, metal inlays, typically made from gold or other alloys, are more durable and less likely to chip or break under normal chewing forces. This durability is a result of the metal's tensile strength and flexibility, allowing it to withstand the forces of occlusion more effectively than porcelain. The aesthetic quality of porcelain is vital, but this comes at the cost of reduced resilience, making careful consideration of its placement crucial in areas of high functional stress.
