Zirconium is becoming the most recommended dental material for dental crowns. The material is extremely durable and comes from a crystal, making it free of metal. The dental crown is custom milled from a single piece of material and then baked at high temperatures. This makes a zirconium dental crown stronger than the softer gold dental crown, and avoids the chipping and breaking of porcelain dental crowns. They are also very desirable cosmetically due to their translucent quality, the lack of a metal base, and the less bulky appearance of the zirconium dental crown. Finally the zirconium dental crown is extremely biocompatible so it will integrate with your mouth very well for the life of the dental crown. The main disadvantage of a zirconium dental crown is the additional cost is usually not covered by insurance companies.
