Cantilever bridge

This medical device related article is a stub.

A cantilever bridge is a type of dental bridge used in restorative dentistry to replace a missing tooth. Unlike traditional bridges, which are supported by crowns on both sides of the missing tooth, a cantilever bridge is anchored on only one side. This makes it a suitable option in areas of the mouth where there is only one adjacent tooth available for support.

Design and Function

The cantilever bridge consists of a pontic, which is the false tooth, and an abutment, which is the supporting tooth. The abutment tooth is prepared to receive a dental crown, which is then attached to the pontic. This design allows the pontic to "cantilever" out from the abutment tooth, filling the gap left by the missing tooth.

Indications

Cantilever bridges are typically used in areas of the mouth that experience less stress, such as the front teeth. They are not usually recommended for the back teeth, where the forces of mastication are greater, as this can lead to complications such as tooth fracture or bridge failure.

Advantages

• Requires less preparation of adjacent teeth compared to traditional bridges.
• Can be a more cost-effective solution than dental implants.
• Provides a fixed solution, unlike removable partial dentures.

Disadvantages

• Increased risk of tooth decay and gum disease around the abutment tooth.
• Potential for tooth mobility or tooth fracture due to uneven distribution of forces.
• Not suitable for all areas of the mouth.

Maintenance

Proper oral hygiene is crucial for the longevity of a cantilever bridge. Patients should maintain regular dental check-ups and clean around the bridge using floss and interdental brushes to prevent plaque accumulation and gum disease.
