What is the primary function of the major connector in a removable partial denture?

The major connector is the component of a removable partial denture that connects the bilateral parts of the prosthesis. Its primary functions are to provide rigidity (preventing distortion under occlusal loading) and to unite all other components — rests, clasps, indirect retainers, and denture bases — into a single functional unit. Common maxillary major connectors include the palatal bar, palatal strap, and horseshoe. Mandibular connectors include the lingual bar and lingual plate. Direct retention is the function of clasps, not the major connector.
