Which of the following is an example of a major connector suitable for a maxillary RPD?

• A. Palatal Plate
• B. Lingual Bar
• C. Retentive Arm
• D. Minor Connector

Answer: (A)

In a maxillary removable partial denture, the major connector needs to span the palate and provide a rigid, cross-arch link that ties the framework together. A palatal plate accomplishes this by offering full palatal coverage, distributing functional loads across a broad area, and delivering the stability needed when the teeth and supporting tissues don’t provide a strong single-span anchor. This broad, passive connection across the palate helps resist tipping and flexing of the framework, which is essential for a stable and comfortable denture. The other options don’t serve as the main cross-arch connector for the upper jaw. A lingual bar is used on the mandible, not the maxilla, and it requires specific vertical space and tissue conditions that aren’t applicable to a maxillary palate. A retentive arm is part of the direct retainer system (clasp) rather than the major connector. A minor connector is a small link that attaches components to the major connector, not the primary cross-arch connector.
