What is the purpose of major connectors in an RPD?

• A. Provide support
• B. Provide esthetics
• C. Provide retention
• D. Provide stability

Answer: (A)

Major connectors are the rigid links that join the components of an RPD across the arch. Their primary function is to distribute functional forces from the denture base to the abutment teeth and residual ridges, effectively supporting the prosthesis. By tying the framework into a single unit, they resist bending and spreading of the denture during chewing, helping keep the base and teeth from excessive movement. Esthetics and retention aren’t provided by the major connector itself—the former is mainly about design and appearance, and the latter comes from direct retainers like clasps or attachments. While major connectors also contribute to stability by maintaining cross-arch rigidity, the key concept they convey here is providing support through proper load distribution.
