Zirconia is a durable, metal-free ceramic material used in dentistry to make crowns and bridges. It is prepared using computer-aided design and manufacturing (CAD/CAM) methods.
Properties
- As it has no metal framework, it does not create a dark appearance at the gum line.
- It is a biocompatible material and may be an option for patients with a metal allergy.
- It can also be used in back teeth, where chewing forces are high.
Process
After the examination, the teeth are prepared, an impression (or digital scan) is taken, a try-in is carried out and the crowns are cemented. Which material is suitable is decided after assessing the condition of the tooth.
