Which of the following is an indication for a lingual plate or linguoplate mandibular major connector?

• A. Weak periodontal support requiring splinting
• B. Strong periodontal support
• C. Absence of mandibular tori
• D. No potential future tooth loss

Answer: (A)

A lingual plate major connector is chosen when teeth have compromised periodontal support and you need to splint multiple abutments across the mandible. The plate sits along the lingual surfaces and provides a rigid, cross-arch connection that distributes functional loads, helping to stabilize mobile or periodontally weakened teeth and prevent tipping or further loss of support. That’s why weak periodontal support requiring splinting is the best answer. If the teeth are strongly supported, a simpler connector such as a lingual bar can often suffice, so the plate isn’t indicated. The absence of mandibular tori isn’t an automatic indication for a plate, and the lack of potential future tooth loss isn’t the deciding factor in choosing this connector.
