The effects of fluorine ion implantation on acrylic resin denture base

Acrylic resin denture base, with fluorine ion implantation at different doses, were compared with reference specimens without ion implantation. The specimens were measured for the quantity of fluorine released for 15 days. It was found that ion implantation caused surface modification of the resin and allowed fluorine ions to penetrate into the polymer. The specimens had the ability to release fluorine into deionized water. Furthermore, the specimens with 10

implantation and the ones with no implantation.
