• A. Palatal plate
• B. Palatal strap
• C. Lingual bar
• D. Palatal extension

Answer: (A)

A major connector on the maxilla should provide solid, uniform support across a broad area when there is extensive edentulous space. The palatal plate does exactly that by spanning a large portion of the hard palate, giving rigid coverage that distributes occlusal loads over a wide surface and to multiple abutments. This rigidity helps prevent deformation or tipping of the denture when chewing and resists the bending moments that can arise with long-span edentulous areas. Other options offer less coverage or are meant for different arches or situations (for example, thinner connectors that preserve taste and comfort, or mandibular connectors), but they don’t provide the same degree of rigidity needed in cases with substantial edentulous support.
