Types of Dental Bridges
There are several types of dental bridges, according to the different techniques and materials used. Here are the most common types:
Traditional Dental Bridge
A traditional dental bridge is made up of one false tooth or several false teeth, fixed in place on either side by crowns. The crowns themselves can be cemented on the patient’s abutment teeth. This is the most common type of dental bridge, recommended for patients with missing teeth or a missing tooth, but with healthy teeth on both sides.
Cantilever Dental Bridge
The cantilever dental bridge is quite similar to a traditional dental bridge, the only difference being that the bridge itself is fixed in place by being cemented on only one of the patient's abutment teeth. Patients require only one healthy and the natural tooth next to the gap for the bridge to be applied.
Maryland Dental Bridges
Maryland dental bridges are similar to traditional bridges in the sense that they both require two healthy teeth on either side of the gap. The only difference between these types of bridges is the fact that while traditional bridges use dental crowns fixed on top of abutment teeth, the Maryland bridge will use a framework often made of porcelain or metal which is fixed to the abutment teeth.
Implant Supported Dental Bridges
Implant supported dental bridges do not use frameworks or crowns to fix the bridge in place. Instead, a dental implant is used to support the bridge and fix it to an abutment tooth. Implant supported dental bridges can also be placed between two or more implant-supported crowns. This is by far the most reliable technique but it also requires the most amount of time, with the procedure divided into two sessions: one to place the implants and another to place the bridge. Dental bridges on front teeth are usually placed using this technique due to its capacity to withstand a great deal of pressure. The cost of dental bridges applied using this technique is also somewhat higher due to the cost of the implant.
