A double lingual bar is also known as which of the following?

• A. Labial bar mandibular major connector
• B. Kennedy bar or Split bar
• C. Swing lock mandibular major connector
• D. Lingual plate

Answer: (B)

In mandibular removable partial dentures, the major connector choices include a lingual bar, lingual plate, or configurations like the double lingual bar when space or anatomy limits a single bar. A double lingual bar consists of two thin lingual bars running along the tongue side of the mandible and is sometimes connected in a way that preserves tongue space while providing cross-arch stability. This design is also known as a Kennedy bar or split bar, terms that reflect its two-bar, divided configuration. The name reflects its function: it splits the standard lingual connector into two elements to accommodate anatomy while still uniting the arch. The other options describe different connectors—labial bar sits on the facial/labial aspect, a swing-lock major connector is a different mechanism, and a lingual plate is a continuous plate along the lingual surfaces—so they aren’t synonymous with the double lingual bar.
