Abstract
We have previously made improvements relating to a denture base lined with soft fluorine resin. This lining material (Kurepeet, Kureha Co.) had qualities of extremely small absorptivity in water, an excellent adhesiveness to the denture base, and long stability in use. This material, however, was not simple in way of use in comparison with the ordinary commercial materials and also had some problems in flexibility.
For solving this defect, we have proposed a method, in which soft fluorine resin is mixed and kneaded well with a fluorine-containg oligomer. The new material simplifys the lining method, because it has a fluidity in the stage of flasking. Also, at the stage where the lining work has been completed, this material will have an ideal hardness with an elasticity.
