The ability of the base to resist occlusal forces and to support the restoration is affected by_______________?
Correct answer: D. Compressive strength
- A. Modulus of elasticity
- B. Tensile strength
- C. Young's modulus
- D. Compressive strength
Explanation
A base must resist the compressive forces transmitted through the restoration during occlusion, so compressive strength is the key property. Tensile strength is more relevant when the material is pulled apart rather than compressed.
