What characteristic of a major connector in a denture is essential for its function?

• A. Provide relief
• B. Does not act as a support element
• C. Rigidity
• D. Stability

Answer: (C)

The rigidity of a major connector in a denture is essential for its function because it plays a crucial role in maintaining the structural integrity of the prosthesis. A major connector must be strong enough to withstand the forces exerted during chewing and protect against deformation or bending. This rigidity ensures that the denture remains stable during functional movements, distributing forces evenly across the bases to avoid discomfort or damage.

In contrast, other characteristics such as stability and relief also have their significance, but without rigidity, the major connector could fail to perform its primary role of supporting the denture effectively. Stability, while important, relies on the underlying rigidity to maintain proper fit and function. Therefore, rigidity is a fundamental property that allows the major connector to perform its intended role effectively in the overall design of a denture.
