A dental bridge is a false tooth which is fused between two porcelain crowns in order to replace a missing tooth. Each bridge is custom made to fill in the space. If spaces are left unfilled the surrounding teeth are liable to drift out of position. Furthermore, spaces from missing teeth can cause your other teeth and your gums to become far more susceptible to tooth decay and gum disease. Bridges are cemented to the natural teeth or implants surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge. A replacement tooth, called a pontic, is attached to the crowns that cover the abutments. As with crowns, you have a choice of materials for bridges.
They can be made of several materials:
- Porcelain fused to metal
- Porcelain fused to titanium
- All porcelain crowns
- Cad cam(all porcelain-zirconia) crowns
Zirconia is an innovative system for esthetic metal-free crowns and bridges. The reliability of zircon restorations is backed by more than five years of proven clinical success. The system is used to fabricate anterior or posterior single units or multi-unit bridge restorations out of translucent, biocompatible zirconia, the strongest and toughest dental ceramic.
