Maryland Bridge – What is Maryland Bridge?
Maryland bridge is one way to replace a missing tooth. It is a type of dental bridge that consists of a metal framework with a porcelain baked artificial tooth which is put into the front of the framework. It has 2 metal wings, one on each side. This bridge was developed at the University of Maryland, thus got its name as Maryland. In this article, we shall know the advantages and a few problems associated with Maryland bridge.
How Maryland Bridge is Attached
The metal wings play an important role in attaching the bridge. These metal wings are prepared to have a porous surface in order to receive a bonding agent. Then the wings are bonded or attached to the back sides of the teeth on either sides of the missing tooth.
Advantages of Maryland bridge
- Dentists find the Maryland bridge as an ultra-conservative treatment for splinting or replacing missing teeth. It is a good aesthetic way that demands minimum amount of tooth modification.
- As it combines a composite resin cemented to acid etched enamel, it is proven for its bond strength. The bond strength is almost 3 fold more than those earlier resin-bonded retainers.
- Even fixed partial dentures periodontal splints and other conservative restorations can be held with a minimum of tooth modification.
- Abutment teeth are not damaged. They are basically left intact.
Problems Associated with a Maryland Bridge:
Though it is valuable, Maryland bridge has 2 main aesthetic problems in regard to the use of metal.
- The first problem is that teeth are translucent. The metal backing will cause the teeth to darken slightly. They have different color than other front teeth.
- The second problem is the false tooth is a porcelain fused to metal tooth. This fusing will make it lack the natural translucency and vitality that other teeth have in them.
The Maryland bridge has been very successful and is used in dentistry for over more than 20 years. The quality and design of the bridge have been proven successful both as a transitional and permanent prosthesis.
