What is the support mechanism for a fixed cantilever bridge?

The most suitable support mechanism for a fixed cantilever bridge is implant support. A fixed cantilever bridge is designed to be anchored at one end, and in dental applications, this is often achieved using dental implants. Implants provide stable, long-term support because they are osseointegrated directly into the bone, creating a strong foundation for the bridge. This allows for effective load distribution and minimizes the risk of complications that can arise from relying on natural teeth, especially when they may not have sufficient structure due to decay or other issues.

While natural tooth support does play a role in some dental bridges, it primarily applies to traditional bridge designs where adjacent teeth are used for support. Bone graft support refers to surgical procedures to enhance bone structure, which is not in itself a direct support mechanism for bridges. Lastly, resin support does not provide the same level of strength and stability as implants; resin can be temporary and is generally used in other forms of dental restorations rather than as a primary support for fixed cantilever bridges. Thus, implant support is the most reliable mechanism in this context, allowing for optimal functionality and longevity of the restoration.
