Which major connector is a broad strap across the palate and commonly used in maxillary RPDs?

• A. Lingual Bar
• B. Buccal Plate
• C. Anterior Connecting Bar
• D. Palatal Strap

Answer: (D)

The main idea is about the types of major connectors used to link the sides of a maxillary partial denture. The broad strap across the palate is the palatal strap. It sits on the hard palate as a wide, relatively thin band that travels from one side to the other, providing rigidity to the denture without covering the entire palate. This makes it a good compromise: it stabilizes the framework and distributes functional loads while leaving more of the palate free, which can improve patient comfort and speech. A lingual bar, by contrast, is used on the lower arch (the mandible), not across the palate. A palatal plate covers a larger portion of the palate than a strap and is chosen when more coverage is needed; an anterior connecting bar is not the standard term for this across-palate connector.
