What material is used to fabricate the metal cast framework for a Removable Partial Denture (RPD)?
Show answer and explanation
Correct answer: A. Base metal alloy
✓ A) Base metal alloy is correct.
RPD frameworks are cast from cobalt-chromium (Co-Cr) or nickel-chromium base metal alloys. These provide the required rigidity, strength, and biocompatibility at a lower cost. Noble metals (gold alloys) are too expensive and too flexible for RPD frameworks. Co-Cr is the gold standard for RPD casting.
