It is helpful to understand the different types of dental bridges to determine why your dentist may recommend a specific one. All dental bridges accomplish the same goal, which is to replace a missing tooth or a section of missing teeth. However, depending on the patient’s goals and the status of their oral health, a certain type of dental bridge may be preferable.
The four main types of dental bridges are fixed bridges, cantilever bridges, Maryland bonded bridges, and implant-supported bridges. Although similar, there are small differences in the treatment processes for each one. This review discusses those processes and the benefits of the four types of dental bridges.
A dental bridge is a fixed dental restoration that replaces one or more missing teeth. There are two main components to a dental bridge: the bridge itself and the abutments. The abutments are natural teeth that are supported by dental crowns. However, a bridge can be supported by dental implants as well.
A fixed bridge is the most common type of dental bridge. This refers to a bridge that is supported by two abutment teeth. The abutment teeth exist on each side of the gap left by the missing teeth. Attached to the abutments are dental crowns, which ensure that the pontic teeth that make up the bridge have adequate support. A fixed bridge likely requires the dentist to remove some of the enamel on the abutment teeth to make room for the bridge. A fixed bridge can be applied to any tooth, including premolars and molars.
A cantilever bridge is similar to a fixed bridge. However, the bridge is only attached to one abutment rather than an abutment on each side. Subsequently, cantilever bridges are less reliable than a fixed bridge, but they still should provide adequate support when they are recommended by a dentist. Of course, not every patient is eligible for a cantilever, depending on the status of their oral health and teeth replacement needs.
Maryland bonded bridges, also called resin-bonded bridges, are most often applied to teeth in the front of the mouth that are more visible. They are held in place by metal or porcelain bands that are attached to the back of the abutment teeth. They are preferable for replacing front teeth because they do not require placing crowns on the abutment teeth. However, they are not nearly as durable as fixed bridges or cantilever bridges.
Implant-supported bridges are bridges that are held together by dental implants. With these types of dental bridges, the implants replace the abutment teeth. This is typically preferred when the patient does not have adjacent teeth that can support the bridge.
