A bruxism patient has a 3-unit PFM bridge in lower molars. The pontic has a chip at the mesial contact area. What is the most appropriate solution?

Correct answer: B. Replace with all-metal bridge with chamfer margin

• A. ❌ A shoulder margin provides more space for porcelain — not the primary advantage when going all-metal for bruxism.
• B. ✅ Correct. For a bruxism patient with chipping porcelain on the pontic, the solution is an ALL-METAL design. Metal is far more fracture-resistant under heavy bruxism forces. A CHAMFER margin provides adequate metal bulk and is the appropriate finish line for metal restorations.
• C. ❌ Simply replacing with another PFM without design modification will result in the same chipping under bruxism forces.
• D. ❌ All-ceramic with shoulder margin is contraindicated for bruxism — ceramic fractures under heavy masticatory loads.
