Prosthodontics & Occlusion · single question
A patient refuses metal restorations and needs a POSTERIOR crown. Best material?
Show answer and explanation
Correct answer: A. Monolithic zirconia
- A. Correct. Monolithic (full-contour) zirconia offers the highest flexural strength/fracture resistance for posterior load-bearing crowns with no metal.
- B. Incorrect. Layered zirconia adds esthetic porcelain but the veneer is prone to chipping under posterior loads.
- C. Incorrect. Lithium disilicate is excellent esthetically (anterior/premolar) but generally less strong than monolithic zirconia for heavy posterior occlusion.
