What type of fixed prosthesis is most likely used to restore a cavity within a tooth?

A ceramic inlay is specifically designed to restore a cavity within a tooth. Inlays are custom-made restorations that fit snugly into the prepared cavity, providing structural support while also returning the tooth to its original function and aesthetics. They are often used when the damage to the tooth is not extensive enough to require a full crown but is too severe for a simple filling. The material used in inlays, such as ceramic, can be selected to match the color of the natural teeth, making the restoration both functional and visually appealing.

The other options represent different types of prostheses that are not specifically used to restore cavities. An adhesive bridge and a cantilever bridge are both designed to replace missing teeth rather than restore damaged teeth. A bonded crown, while it might cover a tooth that has been significantly damaged, is typically not used unless the tooth requires a complete coverage restoration rather than merely filling a cavity.
