RPD Review Questions

Answer to Question #181


The answer is

Bracing and reciprocation are both provided by rigid portions of clasps, guide plates, and minor connectors. Under certain circumstances, linguoplating may also provide bracing and reciprocation. Bracing occurs when the RPD is fully seated. Bracing elements distribute horizontal forces across the arch. Reciprocation is dynamic and requires timing. The rigid elements must contact the abutment teeth as the retentive arms pass over the height of contour during insertion and removal of the prosthesis.
