RPD Review Questions

Answer to Question #130


The correct answer is

Incorrect. Physiologic adjustment is seldom done at the delivery appointment because the denture bases will prevent the exaggerated functional movement needed to adequately mark areas where the framework binds against the remaining natural teeth.

Correct. At the framework try-in appointment, there are no record bases or denture bases to interfere with the exaggerated functional movement required to mark the areas of contact of rigid metal with the natural teeth.

Incorrect. Physiologic adjustment is seldom done at the records appointment because the temporary bases will prevent the exaggerated functional movement needed to adquately mark areas where the framework binds against the remaining natural teeth.

Incorrect. Physiologic adjustment of the framework should always be done for extension RPDs regardless of the strength of the abutments or quality of the residual ridges.
