=== CANTILEVER FIXED PARTIAL DENTURES ===
A cantilever fixed partial denture is used when support can be obtained only from one side of the edentulous space. These dentures have compromised support. The abutment teeth on the supporting side should be strong enough to withstand the additional torsional forces. Support can be obtained from more than one tooth on the same side of the edentulous space.
==== Advantages ====
* Very conservative design especially when a single abutment is involved.
* When secondary abutments are used, parallel preparation can be easily obtained because the abutments are adjacent to one another.
* Easy to fabricate.
==== Disadvantages ====
* Produces torquing forces on the abutment.
* Cannot be used to restore long span edentulous spaces.
* Minor design errors can affect the abutments in a large scale.

This is a special cantilever bridge exclusively designed for replacing maxillary incisors but these dentures can support only a single pontic. Support is obtained from posterior abutments (usually a single molar or a pair of splinted premolars). A long resilient bar connector is used to connect the posterior retainer to the anterior.

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.
{{dictionary-stub1}}
 
== 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]].

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[edit]

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[edit]

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[edit]

Disadvantages[edit]

Maintenance[edit]

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.
