RPD Review Questions
Incorrect. A conventional circumferential clasp cannot be used when the undercut is adjacent to the origin of the clasp (in this case, the distal).
Incorrect. Same reason as #1 and there is no reason to use WW since the RPD is totally tooth-borne.
Correct. The cast clasp would emanate from a mesial minor connector, pass through the embrasure, cross the facial surface of the tooth and engage the distofacial undercut.
Incorrect. Do not use WW through an embrasure. It is difficult to adapt to the occlusal surfaces of the teeth and may interfere with the opposing occlusion. In addition, the slightest nick or kink in the wire will ultimately lead to breakage.
