Abstract
The liquid composition of adhesive resin cement mixed with a fluoride-releasing monomer was examined to develop fluoride-releasing cement having excellent adhesiveness and physical properties. Thus, five types of liquid composites were prepared by mixing 10.0〜40.0 wt% of fluoride-releasing phosphazene monomer (synthesized monomer P3N3(F)1(EMA)5) with commercial monomers. Then, the chronological amounts of fluoride release, tensile adhesive strength between the cement and Co-Cr alloy, Ag-Pd-Au alloy and 18 Karat gold alloy, compressive strength, water sorption and solubility were measured. The results were as follows. Both fluoride release and the cumulative amounts of fluoride release increased in accordance with the increase in the ratio of the synthesized monomer. Tensile adhesive strength between the cement and three kinds of alloys decreased with the increase in the ratio of the synthesized monomer. Compressive strength showed a tendency to increase in accordance with the increase in the ratio of the synthesized monomer. Both water sorption and solubility markedly decreased in accordance with the increase in the ratio of the synthesized monomer.
