In our office, we have our own in-house lab that customizes the shape and shade of crowns and bridges.
Commonly, crowns were made using gold or porcelain. In our office, we use a zirconia alloys base covered in porcelain. We use zirconia as the base because it is generally stronger and more sturdy than porcelain by itself. Zirconia crowns are generally more durable and long lasting. They are also more chip, stain, and temperature resistant compared to that of porcelain.
Overall, zirconia crowns are preferred in our office because they have many benefits and are more cost-effective compared to alternative materials.
