What is the primary purpose of using a dental surveyor during removable partial denture (RPD) treatment planning?

To identify and measure undercuts and determine the most favorable path of insertion/removal for the prosthesis
To measure the patient's vertical dimension of occlusion
To take a final impression
To polish the metal framework

Show answer and explanation

Correct answer: A. To identify and measure undercuts and determine the most favorable path of insertion/removal for the prosthesis

A dental surveyor is a precision instrument used during RPD design and fabrication to analyze the contours of the remaining teeth and ridge, identify and measure undercuts (for retentive clasp placement), establish the most favorable common path of insertion/removal, and locate guide planes — all essential steps before finalizing the RPD design.
