Prosthesis in which a pontic is attached to a single side retainer via connector is called

 # Prosthesis in which a pontic is attached to a single side retainer via connector is called as:

A. Removable fixed partial denture

B. Removable partial denture

C. Fixed partial denture

D. Cantilever fixed partial denture

The correct answer is D. Cantilever fixed partial denture.

A cantilever fixed partial denture is one that has an abutment or abutments at one end only, with the other end of the pontic remaining unattached. This is a potentially destructive design with the lever arm created by the pontic, and it is frequently misused.

Prospective abutment teeth for cantilever fixed partial dentures should be evaluated with an eye toward lengthy roots with a favorable configuration, long clinical crowns, good crown-root ratios, and healthy periodontium. Generally, cantilever fixed partial dentures should replace only one tooth and have at least two abutments.

A cantilever can be used for replacing a maxillary lateral incisor. There should be no occlusal contact on

the pontic in either centric or lateral excursions. The canine must be used as an abutment, and it can serve in the role of solo abutment only if it has a long root and good bone support.
