What is an advantage of a wrought wire combination clasp?

• A. Flexible in any direction
• B. Greater undercut about 0.02 inch
• C. More esthetic
• D. Minimum tooth contact

Answer: (A)

The key advantage is the flexibility of the wire component. Wrought wire is highly ductile, so the clasp segment can bend and spring to engage undercuts from multiple directions. This allows secure retention while accommodating slight tooth movement and distributing forces more softly, which protects the tooth and surrounding tissues. The other options aren’t the main benefit: increasing the undercut is not the goal and isn’t guaranteed by this design; esthetics aren’t the primary advantage since the wire remains a visible, not-inaesthetic feature; and requiring minimum tooth contact would undermine retention rather than improve it.
