Which major connector is indicated for weak periodontal support requiring splinting, presence of mandibular tori, and potential future tooth loss?

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

Answer: (B)

When a mandibular major connector must both splint compromised teeth and accommodate a tori, the lingual plate is the best choice. It wraps around the lingual surfaces of the teeth, giving a rigid, cross-arch framework that distributes occlusal loads across multiple abutments. This rigidity helps stabilize teeth with weak periodontal support, reducing tipping and aiding future tooth loss scenarios by maintaining support across the arch even if some teeth are lost later. A lingual bar would typically be preferred only if there is enough vertical space and no lingual tori; with tori present, it would interfere or be impractical. The double lingual bar is considered when space is limited but can still fall short of providing the same bulk and splinting effect as a plate, especially in the context of tori. A palatal connector is used for maxillary arches, not the mandible.
