Which term describes the component that bribes the tooth against the action of the retentive arm?

• A. Rest
• B. Retentive arm
• C. Bracing arm
• D. Minor connector

Answer: (C)

In a clasp system, the retentive arm engages an undercut to provide retention, but this action tends to pull the tooth toward the denture and away from its natural position. The bracing arm is the part that presses against the tooth on the opposite side of the undercut, distributing the load and resisting that pull. This opposing force stabilizes the tooth and prevents unwanted movement or rotation as the denture is engaged or removed. The rest provides vertical support to the denture base, while the minor connector simply links components on different teeth and isn’t involved in counteracting the retentive arm. So the component that braces the tooth against the action of the retentive arm is the bracing arm.
