Dental Bridges

Maryville and Knoxville, TN

Dental bridges can be made of various materials and come in many different sizes. The most common bridge these days is made out of porcelain and spans three teeth.

The bridge is tooth colored and is designed to replace three front teeth on the upper arch. If this bridge were on the bottom, it would look about the same, except that the chewing edges would be facing up, and the part that holds onto to the roots would be at the bottom.

Another example of an upper dental bridge, involves all six anterior teeth. Here, the teeth may be made as one solid piece, or may be made as two separate bridges, spanning a total of six teeth. Again, this bridge is an example of an upper dental bridge. A lower would be similar, but facing up.

Finally, there are bridges that can span a total arch. In these cases, the bridge is sometimes made of zirconium, and is designed to be stronger than a normal porcelain bridge This is an example of a fourteen-unit upper porcelain dental bridge.

With these stronger materials, we can make a single bridge to cover an entire arch. While this type of reconstruction is not that common, it is possible. In our office, we have made many full arch bridges.

Other types of dental bridges:

Full gold bridges.

While these are not that common anymore, it is possible to cast and cement solid gold bridges.

Posterior porcelain-fused-to-gold bridges.

These are more common, and have the added advantage of having a metal substructure for rigidity and marginal fit.

Removable bridges.

These are quite uncommon, but can be made when the fixed bridge is not recommended.

Maryland bridges.

This type of bridge is a special method of restoration where the teeth on either side of the missing one are not prepared.
