DENTAL PHOTOPOLYMERIZABLE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a photopolymerizable composition having a low polymerization shrinkage and excellent fluidity even when the compounding ratio of an inorganic filler is relatively high in order to provide excellent mechanical properties of a cured product after curing, and suitably usable as a flowable composite resin. SOLUTION: This dental photopolymerizable composition comprises 100 pts. mass of a polymerizable monomer, 100-400 pts. mass of the inorganic filler and an effective amount of a photopolymerization initiator. In the dental photopolymerizable composition,≥60 mass% of particles having≥0.03 to <0.1μm particle diameter in the inorganic filler are silica-zirconia spherical inorganic oxide particles.
