Metal base denture bases are associated with which characteristic?

• A. Maximum strength
• B. Inability to support tissue
• C. High porosity
• D. Low fracture resistance

Answer: (A)

metal base denture bases are known for their high strength and rigidity. Using metal alloys such as cobalt-chromium gives a base that resists bending and fracture under chewing forces, so the denture can be thinner yet durable. This combination of strength and stiffness means the base reliably supports the denture and distributes loads to the supporting tissues without easily breaking. In contrast, materials with high porosity would compromise strength and stability, and a low fracture resistance would contradict the durable performance metal provides. The ability to withstand functional stresses is the hallmark of metal-based bases, which is why maximum strength is the best descriptor.
