Surface Modification of Denture to Provide Contamination-Free Ability by Using Silane Coupling Agent Containing Fluorocarbon Chain

Silane coupling agent containing fluorocarbon chain, (1H,1H,2H,2H-henicosafluorododecyl)trimethoxysilane, was applied for the surface modification of some dental materials. The contact angles of water and oleic acid on the modified material surfaces were increased. The modified denture teeth worn in an oral cavity displayed a long-range stain-protecting ability.
