Prosthodontics & Occlusion · single question
An epileptic patient needs a posterior crown on #19 and dislikes the metal collar on his current restoration. What is the best option?
Show answer and explanation
Correct answer: B. Monolithic zirconia
- A. PFM would reproduce the exact metal display the patient objects to.
- B. Correct. Monolithic zirconia is metal-free, esthetic, and offers the highest fracture resistance — an important consideration for a patient at risk of trauma or bruxism during seizure activity.
- C. Gold is durable but has the greatest metallic display.
- D. Feldspathic porcelain is the weakest option and unsuitable for a posterior molar under load.
