What RPD component is described as a rigid and bulky element that connects all parts of the denture together?

• A. Minor Connector
• B. Direct Retainer
• C. Major Connector
• D. Indirect Retainer

Answer: (C)

The major connector is the rigid, bulky piece that ties all parts of the removable partial denture into a single, unified framework. It runs across the arch (for example, a palate-spanning connector on the maxilla or a lingual connector on the mandible) and serves as the backbone of the denture. Its primary role is to distribute functional forces over a broad area and across multiple abutment teeth, preventing excessive bending or movement of the denture during chewing. By linking rests, indirect retainers, clasps, and denture bases, it ensures the components work together rather than as separate pieces. Because it must resist bending and maintain stability under load, its design is relatively thick and continuous, which is why it’s described as rigid and bulky. In contrast, minor connectors are smaller links to the major connector, direct retainers provide retention, and indirect retainers help resist rotation—none of these serve the same overarching connecting function across the arch.
