Dental Bridges, also called fixed partial dentures, are a popular type of non-removable prosthetic dental appliances used in the treatment of missing teeth. Dental bridges are so called because they literally bridge the gap between two teeth.
Typically, a bridge consists of one or more artificial teeth held in place by two dental crowns on either side. A bridge is placed by the dentist such as that the dental crown, or abutments, are secured to the natural teeth on either side of gap while the artificial teeth, or the pontics, fill in the space.
Dental Bridges serve the aesthetic purpose of allowing you to show off your beautiful smile with the fear or shame of imperfect smile. The dental bridges are a common, low-risk, affordable and time-tested treatment.
Dental bridges can be made out of a variety of different materials such as gold, silver amalgam, or other metal alloys, but for aesthetic considerations, bridges made from all porcelain or porcelain fused to metal are the most commonly used. Dental bridges are also made from a newer, advanced type of dental ceramic, Zirconia.
Types of Dental Bridges
There are 4 basic types of dental bridges
- Traditional Bridges
- Maryland Bonded Bridge
- Cantilever Bridge
- Implant Supported Bridges
- Traditional Bridges
Traditional bridges are the most common types of bridges and are made from either porcelain fused to metal or ceramic. These bridges typically involve the preparation of two natural crowns on either side of the gap in a patient’s smile to support the bridge itself. The dentist re-shapes the teeth in order to make room for the bridge.
Maryland Bonded Bridge
Named after the researchers at the University of Maryland, the Maryland Bonded Bridges are resin bonded where the pontic tooth is fused to the metal bands or wings which are attached to the backs of the adjacent teeth. This type of bridge is popular because it involves the bare-minimum alteration of the surrounding teeth, only requiring micro-etching to create a strong bond between the bridge and the supporting teeth.
A Cantilever dental bridge is typically used when there are adjacent teeth on only one side of the missing tooth or teeth. Usually they can replace only one single tooth. For the placement of a cantilever bridge, the crown of one adjacent tooth is prepared which supports the entire restoration. These types of bridges are normally not recommended for the replacement of the back teeth or the molars.
Implant Supported Bridges
A relatively newer alternative to traditional bridges, where natural tooth structure was reduced in the preparation and placement of bridges, are the Implant Supported Bridges. A dental implant is a titanium post which is surgically placed into the alveolar bone of the jaw. Later on, the dentist places a custom-fabricated crown restoration directly on top of the implant core. These types of bridges are commonly used when there are no adjacent teeth present to act as anchors for the traditional dental bridge.
No matter what the type of bridge a patient receives, dental bridge restorations have significant practical benefits. The dentists at Bright White Dental Centre are experts in the placement of dental bridges. Thanks to their expertise and experience in combination with the use of advanced dental technological techniques, the bridges placed not only restore complete dental functionality and oral health; they are also virtually indistinguishable from the patient’s natural dentition.
