What are the auxiliary functions of indirect retainers?

• A. Provide major connector
• B. Distributing occlusal forces
• C. Indicator for relining
• D. Aid in stabilization

Answer: (D)

Indirect retainers act as stabilizers for an RPD. Placed on the side opposite the primary support, they create a secondary fulcrum that resists tipping and dislodgement of the denture when functional forces push on the free-end saddle. In other words, their job is to keep the denture seated and stable during use, not to provide the main retention, to directly distribute occlusal loads, or to indicate relining. This stabilizing role is why they’re best described as an aid in stabilization.
