A bridge is a dental restoration used to replace a missing tooth by joining permanently to adjacent teeth or dental implants.
Types of bridges may vary, depending upon how they are fabricated and the way they anchor to the adjacent teeth. Conventionally, bridges are made using the indirect method of restoration. However, bridges can be fabricated directly in the mouth using such materials as composite resin.
A bridge is fabricated by reducing the teeth on either side of the missing tooth or teeth by a preparation pattern determined by the location of the teeth and by the material from which the bridge is fabricated. In other words, the abutment teeth are reduced in size to accommodate the material to be used to restore the size and shape of the original teeth in a correct alignment and contact with the opposing teeth.
What are the benefits of dental bridges?
- Restore your smile
- Restore your ability to properly chew and speak
- Maintain the shape of your face
- Distribute the forces in your bite properly by replacing missing teeth
- Prevent remaining teeth from drifting out of position
What types of dental bridges are available?
There are three main types of bridges:
- Traditional bridges involve creating a crown for the tooth or implant on either side of the missing tooth, with a pontic in between. Traditional bridges are the most common type of bridge and are made of either porcelain fused to metal or ceramics.
- Cantilever bridges are used when there is an adjacent tooth on only one side of the missing tooth or teeth.
- Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made of porcelain fused to metal teeth supported by a metal framework. Metal wings on each side of the bridge are bonded to your existing teeth.
