MARYLAND BRIDGE OR RESIN - BONDED BRIDGE







There are several different types of dental bridges with one of the most common types being the resin-bonded bridge also known as the Maryland Bridge

The Maryland Bridge is an ultra-conservative treatment option that enables the dental practitioner to splint or replace missing teeth esthetically with an absolute minimum amount of tooth modification. This type of bridge combines a composite resin cemented to acid etched enamel and an acid etched cast metal framework. The Maryland Bridge improves the bond strength of the restoration three-fold over earlier perforated resin-bonded retainers.

With the Maryland Bridge fixed partial dentures periodontal splints and a variety of other conservative restorations can be placed with a minimum of tooth modification. Abutment teeth are basically left intact and not damaged.

Modifications of the bridge are restricted but all tooth preparations are supragingival (above the gingiva) making modifications kinder to the periodontal tissues and impressions easier to obtain. The preparation for a Maryland bridge does not involve the dentin so sensitivity is virtually eliminated either from the preparation or subsequent cementation procedure. Most importantly as the Maryland Bridge requires little or no removal of tooth structure the treatment is often reversible.

The Maryland Bridge has been used successfully for over 20 years. The quality and design enhancements of this cast resin-bonded bridge have been proven successful both as a transitional and/or permanent prosthesis particularly where there is a reluctance to perform extensive reduction on a good tooth.

As with all types of bridges it is important to maintain proper oral hygiene. With proper oral hygiene bridges can last up to ten years. However improper or infrequent brushing and flossing irregular dental visits and excessive sugar and starch intake can all bring untimely damage to the bridge.
