Which is a function of denture bases?

• A. Cosmetic effect of the replacement (teeth and tissue)
• B. The ability to produce metal shine
• C. The creation of vertical furrows
• D. The increasing of ridge resorption

Answer: (A)

The denture base mainly provides a stable, tissue-supported foundation that covers the edentulous ridges and helps position the artificial teeth to achieve proper facial aesthetics. This direct influence on how the replacement looks—teeth and surrounding tissue—makes cosmetic restoration a key function of the denture base. The other statements aren’t functions of the base: producing metal shine isn’t a role of the denture base, it relates to metal components; creating vertical furrows isn’t a purpose of the base; and increasing ridge resorption would be an undesirable outcome, whereas a well-designed base aims to distribute loads to help preserve the supporting tissues.
