Which statement correctly identifies the major connector in an RPD?

• A. The major connector is a minor component that spans only one side.
• B. Rests provide vertical support.
• C. The major connector is the main continuous uniting component across the arch.
• D. Retentive arms provide retention.

Answer: (C)

The major connector is the main continuous uniting component across the arch. It provides rigidity to the framework and distributes functional loads between abutments, connecting the left and right sides so the denture won’t flex or detach. That’s why the statement describing it as the main continuous uniting component across the arch is the best fit. Rests are designed for vertical support on abutment teeth, and retentive arms (clasps) provide retention, not the primary cross-arch connection. A major connector is not a minor component confined to one side. In practice, it spans the arch (for example, a palatal plate in the maxilla or a lingual bar/plate in the mandible) to achieve this cross-arch unity.
