A fixed cantilever bridge is a type of permanent dental restoration used to replace a missing tooth, uniquely anchored by one or more adjacent teeth on only one side of the space.
Understanding Fixed Cantilever Bridges
Based on the provided information, a cantilever bridge is a type of fixed dental prosthesis that's anchored by one or more abutment teeth only on one side of a gap left behind by a missing tooth. The term "fixed" highlights that this type of bridge is permanently cemented or bonded into place and cannot be removed by the patient.
Unlike traditional dental bridges that are supported by teeth on both sides of the gap, a cantilever bridge relies solely on support from one side. This design means the replacement tooth (called a pontic) is suspended over the missing tooth space, attached only at one end to the supporting (abutment) tooth or teeth.
Key Characteristics
A fixed cantilever bridge is defined by several core features:
- Fixed Dental Prosthesis: It is a non-removable restoration cemented onto existing teeth.
- Anchored Unilaterally: The bridge is supported exclusively by abutment teeth located on just one side of the missing tooth gap.
- Replaces a Single Tooth: Typically used to replace one missing tooth, though variations exist.
- Consists of Pontic and Retainers: Includes the artificial tooth (pontic) and the crowns (retainers) that fit over the abutment teeth.
Practical Application
Fixed cantilever bridges may be considered when there are suitable strong teeth available adjacent to the missing tooth, but only on one side of the gap. They are often used in areas of the mouth that experience lower chewing forces to minimize stress on the single-sided anchorage.
