RPD Review Questions
Incorrect. A mesial
rest and an I-bar is the BEST choice.
Correct. A distal
rest and cast circumferential clasp has the greatest potential for
torquing the abutment during functional movement of the extension
base.
Incorrect. Although
the half and half clasp is not our first choice retainer, it is
acceptable when lack of a facial undercut necessitates the use of a
lingual undercut.
Incorrect. A mesial
rest and modified T-bar is an acceptable clasp assembly when the
undercut is on the distofacial surface and when there is no
contraindication to the use of a bar (infrabulge) clasp.
