This is a crown that leaves one or more axial surfaces uncovered (Fig 6-13). Therefore, it can be used to restore a tooth with one or more intact axial surfaces with half or more of the coronal tooth structure remaining. It will provide moderate retention and can be used as a retainer for short-span fixed partial dentures. If tooth destruction is not excessive, a partial coverage crown with a minimally extended preparation and carefully finished margins can satisfy moderate esthetic demands in the maxillary arch.
