The correct function of a major connector in dentures is to provide rigidity to the denture base. This rigidity is essential for the overall stability and support of the denture, ensuring that forces during chewing and speaking are efficiently distributed across the entire prosthetic and down to the underlying oral structures. A major connector serves as a unifying component that connects various parts of a partial denture and helps maintain its position in the mouth, reducing the potential for movement and discomfort.

While flexibility can be important in certain components of the denture, the major connector is designed to resist deformation during function. Its strength and stability are crucial, especially in areas where the denture experiences significant stress, ensuring that the prosthesis is functional and comfortable for the patient. Therefore, the focus on rigidity is vital for effective occlusion and support.

The other choices do not align with the primary function of a major connector. Engaging undercuts, for instance, is generally the role of clasps and not the major connector. Flexibility during chewing is not a desired property of a major connector, as it needs to maintain form under functional forces. Although it is true that dentures can be removed for cleaning, this is more related to the overall design of the prosthesis rather than the specific
