HOSA Dental Terminology Practice

Which type of bridge is described as being cemented directly to adjacent teeth?

1. Resin-bonded bridge

2. Fixed bridge

3. Onlay

4. Full crown

The correct answer is: Resin-bonded bridge

A resin-bonded bridge, often referred to as a Maryland bridge, is specifically designed to be attached directly to the adjacent teeth using a resin adhesive. This type of dental bridge is less invasive than traditional bridges, as it typically requires minimal alteration to the supporting teeth. The wings of the bridge are bonded to the back of the adjacent teeth to provide support and stability without the need for extensive crown preparation. In contrast, a fixed bridge usually involves more substantial preparation of adjacent teeth to accommodate crowns, which are then connected by a pontic (the false tooth). An onlay is a type of indirect restoration that covers a portion of a tooth rather than serving as a bridge. A full crown entails encasing an entire tooth in a cap to restore its function and appearance, which is different from the concept of a bridge that spans gaps between teeth.
