The Effect of a Fluorinated Copolymer Coating Agent on Tissu Conditioners

This study examined the intraoral changes of the elastic properties and roughness of a tissue conditioner after treatment with a fluorinated copolymer coating agent developed by the authors. The surface of the conditioner was t reated with the agent on half of the internal surface of five maxillary complete dentures and was compared with the untreated half on the other side. The cushioning effects of the conditioners were evaluated by measuring the creep compliance strain-to-stress ratio. The value of compliance on the treated half was significantly greater than that on the untreated half. There was significantly less roughness on the treated side than on the untreated side. It was found that the coating provides an improved, glossy surface to the conditioner and may increase its useful life.
