CASE — Crown problem. Given the visible attrition (likely bruxism) plus the esthetic demand, the most appropriate replacement crown material is:
Show answer and explanation
Correct answer: B. Monolithic zirconia (strong and esthetic)
- A. Gold is durable but fails the esthetic requirement in a visible area.
- B. Correct. Monolithic zirconia provides high strength for a bruxer plus an esthetic, metal-free result (avoiding the previous metal-margin problem).
- C. A thin feldspathic veneer is too weak for a bruxing patient and won't restore a full crown.
- D. Acrylic is only a temporary material.
Note: A PFM would risk repeating the visible metal-margin esthetic problem; all-ceramic zirconia avoids that.
