Which major connector is located on the labial aspect of the mandible?

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

Answer: (C)

The key idea is the location of the major connector on the mandible. A labial bar major connector sits on the labial (lip-facing) surface of the mandible, crossing the labial vestibule to connect the framework. This option is chosen when the lingual route isn’t feasible due to anatomy or space constraints, making the labial path the practical alternative. The other designs listed are either on the lingual aspect (double lingual bar) or are special types of connectors that don’t sit on the labial surface (swing-lock, Kennedy/split bar). Therefore, the labial bar mandibular major connector is the one located on the labial aspect.
