FPD, fixed partial denture; RPD, removable partial denture; NA, not applicable; rev, reverse; prox, proximal.

*Dependent on tooth position, location of restoration (mesial or distal), and patient expectation.

^†Structurally sound, but not esthetic.

^†An acceptable compromise treatment if cusps are capped with amalgam.

^§May offer some protection in conjunction with etching and bonding.

^||When used with a core or foundation restoration.

^¶Can be used to replace an incisal corner.
