In the design of a major connector for a removable partial denture (RPD), the primary goal is to provide strength and rigidity. The major connector acts as a framework that connects the different components of the prosthesis, distributing functional forces evenly across the tissues in the oral cavity. It is essential that the connector withstands the occlusal forces generated during chewing without deformation, which could lead to discomfort or compromised fit.

Strength and rigidity are crucial for maintaining the structural integrity of the RPD. If the connector is weak or flexible, it could result in movement that affects the retention and stability of the denture, potentially leading to issues with function and patient comfort. Moreover, a well-designed major connector contributes to overall support for the remaining teeth and soft tissues, ensuring effective load distribution.

While aesthetics, coverage of the palate, and minimizing metal usage are important considerations in the overall design of the RPD, they are secondary to the primary goal of strength and rigidity. Aesthetic considerations may influence the materials used or the design itself, but they cannot compromise the need for a strong and stable framework. Similarly, while sufficient region coverage and minimizing materials are practical aspects of RPD design, they do not outweigh the fundamental requirement of providing a robust structural foundation.
