Which clasp setup is essentially two joined circumferential clasps?

• A. Embrasure clasp
• B. Ring clasp
• C. Reverse action clasp
• D. Wrought wire combination clasp

Answer: (A)

In removable partial dentures, an embrasure clasp uses two circumferential clasps on adjacent teeth that are linked by a bar passing through the embrasure between them, so it behaves as two clasps joined together. This arrangement takes advantage of the interdental space to provide retention while distributing support across both abutments. The other designs differ: a ring clasp encircles a tooth rather than forming a joined pair across an embrasure; a reverse action clasp changes the direction of retention on a single clasp rather than creating two clasp segments connected through the embrasure; and a wrought wire combination clasp combines wire with a cast component, not simply two circumferential clasps joined across an embrasure.
