There are three types of bridges:
- Traditional fixed bridges
- Resin bonded bridges (also called Maryland bridges)
- Cantilever bridges
Traditional fixed bridges are fused between two porcelain crowns that are anchored to two natural teeth. Fixed bridges are not removable as partial dentures are. These are the most common type of dental bridge. Fillings work well with this kind of bridge because the filling can act as a foundation for the crowns.
Resin bonded bridges, or Maryland bridges, are generally used for front teeth. These bridges are less expensive, but also not as strong as traditional bridges. Resin bonded bridges are best used when the abutment (supporting) teeth are healthy and don’t have large fillings. In these bridges, the false tooth (pontic) is fused to metal bands that are fused to the supporting teeth. This type of bridge requires less work on surrounding teeth.
Cantilever bridges are used where teeth are under less stress, as in front teeth. These kind of bridges only require teeth on one side of the open space. Cantilever bridges anchor the pontic to healthy teeth on one side of the false tooth.
