What factor can lead to deformation of dental restoration during function?

Deformation of dental restorations during function can indeed be influenced by inappropriate alloy selection. The choice of alloy for the restoration is crucial, as different materials have varying physical properties, such as strength, ductility, and resistance to deformation under load. If a dentist selects an alloy that is not suited for the specific functional demands of the restoration, the material may not withstand the stresses imposed during chewing and other functions. For example, an alloy that is too soft or lacks adequate tensile strength may yield or deform under normal occlusal forces, compromising the integrity of the restoration and potentially leading to failure.

This highlights the importance of selecting an appropriate alloy based on the specific clinical situation, such as the location of the restoration, the expected biting forces, and the needs of the patient. A proper understanding of material properties is essential for ensuring the longevity and functionality of dental restorations.
