What is a primary consideration when designing a major connector around a palatal torus?

• A. Retention
• B. Flexibility
• C. Rigidity
• D. Aesthetics

Answer: (C)

When designing a major connector around a palatal torus, rigidity is a primary consideration because it ensures that the prosthetic device maintains its form and function under the stresses of mastication and everyday use. A rigid major connector provides stability, effectively distributing the forces exerted on it across the entire dental arch. This is crucial in areas where anatomical challenges like a palatal torus exist, as a flexible connector could lead to movement that would compromise the prosthesis's function, lead to discomfort, or even damage the surrounding soft tissues. In contrast, while retention is important for keeping the prosthetic in place, the primary challenge presented by the palatal torus necessitates a design that does not flex and maintains integrity against applied forces. Flexibility, while useful in some contexts, would not support the necessary stability required in this situation. Aesthetics, while always valued in prosthetic design, does not supersede the functional need for rigidity when addressing the unique anatomical features such as a palatal torus. Thus, the focus on rigidity is paramount for a successful and durable prosthesis.
