In the RPD framework, which connectors are primarily responsible for stability?

• A. Major connectors
• B. Minor connectors
• C. Retentive posts
• D. Occlusal rests

Answer: (B)

Stability in an RPD framework comes from how forces are distributed across the arch and how the framework is tied together. Minor connectors are the small links that connect the major connector to rests, indirect retainers, and other components. They act as the pathways through which functional loads are transferred from the teeth and mucosa to the rigid major connector, spreading stresses and preventing localized flexing or movement of the denture. While the major connector provides the overall rigidity of the system, minor connectors ensure that this rigidity is effectively shared by all parts of the denture, which is what keeps the appliance stable during function. Retentive posts provide retention, rests give vertical support, and major connectors supply cross-arch rigidity, but stability hinges on how well the minor connectors tie everything together and distribute forces.
