When choosing materials for denture bases, which factor is most critical?

When selecting materials for denture bases, resistance to fracture is of paramount importance. Denture bases must endure daily mechanical stress, including chewing forces and impacts during insertion and removal. Materials with high fracture resistance contribute significantly to the durability and lifespan of the denture, ensuring that it maintains its structural integrity under functional loads. This quality not only affects the longevity of the denture but also impacts the overall functionality and effectiveness of the dental prosthesis.

While patient comfort, cost-effectiveness, and considerations regarding allergic reactions are certainly important in the selection process, they generally come after the primary concern of structural resilience. A denture that fractures easily would not provide the comfort or functionality necessary for effective use, regardless of its cost or biocompatibility. Therefore, prioritizing resistance to fracture ensures that the denture can perform as needed in a patient's daily life, making it a critical factor in the choice of materials.
