For which purpose is a complete cast crown not typically used?

A complete cast crown is specifically designed to cover and restore the entire coronal portion of a tooth, providing strength, protection, and aesthetic improvement. Its primary usage includes restoring a single tooth, serving as a retainer for fixed dental prostheses, and acting as a support for partial removable dentures.

The use of a complete cast crown as a retainer for a complete removable denture is not typical because complete dentures do not rely on individual teeth for retention. Instead, complete dentures obtain stability and retention through the anatomical contours of the edentulous ridge and surrounding soft tissues. In contrast, fixed or partial prostheses do rely on adjacent teeth or prepared abutments for anchorage, making crowns suitable in those contexts. Thus, the primary role of a complete cast crown is not aligned with the needs associated with complete removable dentures.
