Full or partial dentures are prosthetic devices designed to replace missing teeth. They consist of a gum-colored base made from plastic resin that fits snugly over the remaining bone ridge that once supported the teeth. The prosthetic teeth are meticulously crafted to resemble and function like natural teeth. The stability of properly fitted dentures is primarily dependent on the suctioning effect created by their close fit against the bone ridge. The expansive surface area of the palate provides additional support for the upper denture, enhancing its overall stability.
