Which clasp setup is shown?

• A. Wrought wire combination clasp
• B. I-bar clasp
• C. T-bar clasp
• D. RPI

Answer: (A)

The main idea is recognizing how different RPD clasps grip the tooth and attach to the framework. The image shows a very fine, flexible wire that forms a looping retentive portion around the tooth, attached to a small anchor coming from the rest of the denture. That combination of a wrought wire loop with a supportive component is what defines a wrought wire combination clasp. This is distinct from a rigid I-bar, which would appear as a solid straight or curved bar running along the tooth surface; a T-bar, with a T-shaped crossbar at the end of the retentive arm; and the RPI design, which includes a proximal plate engaging the tooth and a separate rest and I-bar arrangement. Those configurations look noticeably different in form and attachment compared to the delicate looping wire seen here. So, the image’s look—a slender wire loop providing retention around the undercut while tying into the denture framework—best matches a wrought wire combination clasp.
