RPD Review Questions

Answer to Question #98


The correct answer is

Incorrect. Too high. It is difficult to prepare an adequate rest seat and the potential for torquing forces on the abutment teeth are increased. In the maxillary arch there would also be the increased potential for interference with the opposing occlusion.

Incorrect. Too high. Same reasoning as for answer #1.

Correct. This location places the rest seat and rest just above the cingulum but as low as possible so that potential torquing forces on the abutment are minimized.

Incorrect. Totally nonsensical.
