Prosthodontics & Occlusion · single question
For a patient with bruxism, which single-crown material is generally the most fracture-resistant choice?
Show answer and explanation
Correct answer: D. Monolithic zirconia
- A. Incorrect – reasonable for posterior strength, but monolithic zirconia is the preferred modern choice for bruxers needing esthetics + strength.
- B. Incorrect – acceptable, but porcelain can chip; a full-metal occlusal is stronger.
- C. Incorrect – lower strength/veneer chipping risk under bruxism.
- D. Correct – monolithic (full-contour) zirconia has very high flexural strength and no veneer to chip, ideal for heavy parafunction.
