Which major connector contacts the teeth just above the cingulum rests at each end?

• A. Lingual Bar
• B. Lingual Plate
• C. Double Lingual Bar
• D. Palatal Connector

Answer: (B)

The major connector that can contact the teeth right where the cingulums rise is the lingual plate. A plate sits on and around the lingual surfaces of the anterior teeth, so it can extend to and touch the enamel just above the cingulum rests at each end. This close adaptation at the incisor area provides stable support and effective distribution of forces without interfering with the rests themselves. In contrast, a lingual bar stays lower on the lingual surfaces and typically does not contact the tooth right above the cingulum rests, especially when space or clearance is limited. The palatal connector is used on the palate rather than along the lingual surfaces, and a double lingual bar is chosen mainly for space constraints but does not specifically address contact above the cingulum rests in the same way a plate does.
