We embedded tannin-fluoride preparation with the zinc oxide eugenol cement as the filling material to the inner surface of denture base to which the abutment might contact, and reported that it was useful to prevent caries of the overdenture abutment teeth. But we anticipated the weakness of mechanical strength of the denture. In this study we produced autopolymerizing resin containing the preparation, and the F-ion solubility, setting time, Knoop Hardness, adhesive strength and compressive strength were measured. The following results were obtained : 1) The F-ion solubility was increased as the mixing ratio increased. 2) Setting time was increased as the mixing ratio increased. 3) The values of Knoop Hardness from 10 to 50% groups were lower than that of 0% group, and there was no statistical difference between the values from 10 to 50% groups. 4) The values of adhesive strength of mixing ratio from 10 to 30% groups showed almost the same value as that of 0% group. 5) The values of proportional limit of compressive strength of 10 and 20% groups showed almost the same value as that of 0% group.
