RPD Review Questions

Answer to Question #162


The correct answer is

Incorrect. Camper's line has nothing to do with RPD design.

Incorrect. There is no such thing as Frankfort's line.

Incorrect. There is no such term as "dual path line."

Correct. If extension RPDs are properly designed, this line should pass through the most distal rests. To be sure this is true, one must be careful that there is no other rigid metal above the survey line that is closer to the edentulous segments.
