Though it is valuable, Maryland bridge has some problems in regard to the use of metal and the longevity of the bridge bonding.
- It is used only when one tooth is missing
- The teeth are translucent. The metal backing will cause the teeth to darken slightly, so the result is a slghtely different color than other front teeth. To overcome this problem we design the framework to fit at the palatal portion of the tooth.
- The false tooth is a porcelain fused to metal. This will make it lack the natural translucency and vitality that other teeth have in them.
- There is a tendency of the metal wings to debond, depending on the chewing forces applied on the bridge. Therefore the bridge has to be recemented every few years.
In conclusion: The Maryland bridge has been 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. It can last over ten years if one takes relevant care of it and mantains a good hygiene regime.
