Correct answer: C — Distributing forces across the arch by rigidly connecting all RPD components, preventing independent movement of any single component
The rigid major connector 'splints' all RPD components together (denture bases, clasps, rests, minor connectors), ensuring they function as a unified prosthesis rather than independent parts. This distributes occlusal and lateral forces across multiple abutment teeth and the residual ridge rather than concentrating forces on individual teeth. Without adequate rigidity, the RPD would flex under load, concentrating destructive forces on individual abutments and accelerating their periodontal breakdown.
