A clear comparison between the zirconia crown (metal-free) and the metal-ceramic crown: esthetics, the gray line at the gum, strength, durability and when each one is right. I help you choose the correct material for your case in Medellín.

Zirconia: maximum strength with excellent aesthetics

Zirconia (zirconium dioxide or ZrO₂) is a high-strength ceramic material that has revolutionized restorative dentistry over the past 20 years. Zirconia crowns can withstand masticatory forces of 900 to 1,200 MPa, making them virtually unbreakable under normal clinical conditions.
