Which major connector is preferred when mandibular tori are present?

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

Answer: (B)

When a mandible has tori, there isn’t enough vertical space for a lingual bar to sit comfortably without contacting the torus or irritating the floor of the mouth. A lingual plate, by contrast, runs along the lingual surfaces and can be contoured to wrap around or bypass the torus, providing a rigid major connector without requiring the clearance a bar needs. It distributes load across the arch and minimizes trauma to the tissue or interference with the torus, making it the safer, more adaptable choice in this situation. The other options either rely on the available space for a bar (which is limited by the torus), are less suitable when large tori are present, or apply to the maxillary arch (palatal connector), so they’re not ideal in this scenario.
