With a view to clinically applying the Visible Light Curing Denture Base resin, the authors have conducted a series of basic studies. As a result, it has been concluded that some comrositional improvements will be rectuired of this resin because of such shortcomings as its amine smell and bitter taste. The authors, therefore, trially produced Visible Light Curing Denture Base resin by combining the monomers, sold on the market, in various ways. As for the monomers used in this experiment, the authors produced a mixture by first adding to the naonomer sold on the market a combination of Cyclophosphazene monomer {4PN-(TF)_2-(EMA)_6} as a new type of dental monomer, and then further adding the PMMA polymer and the filler. In the course of the studies made this time, the authors also trially produced a compound based on the composition of this resin. This compound, which possesses a large flow, was produced as relining material. A comparative study was then made of this compound and the Dentsply Triad VLC Direct Reline Material, which had recently been put on sale, with regard to the physical properties and fitness. As a result of such comparative studies, it was found that the trially-produced relining material, as compared with the Triad, showed good values with regard to its mechanical property. As to the fitness, no gap was observed between the palate and the cast in the deepest part of the palatal cavity.
