A palatal plate major connector is preferred when there is no interfering palatal torus.

• A. Torus present
• B. Interfering torus
• C. No interfering torus
• D. Only for Class I

Answer: (C)

The main idea is that the palatal plate major connector works best when the palate can accommodate it without bumping into any bony prominences. A full palatal plate sits across the palate and provides rigid, stable connection of the denture framework, spreading occlusal loads evenly and resisting flexing. If there is no interfering palatal torus, the plate can seat smoothly along the midline and across the palate, giving maximum rigidity and good support for the other components. If a palatal torus is present and interferes with seating, a full palatal plate would press on or irritate the torus, leading to poor fit and discomfort. In that situation, an alternative connector that avoids the torus would be chosen, rather than forcing a plate through an obstructing torus.
