The invention provides a fluoride ion releasing dental composition including an inorganic powder (a); a fluoride ion releasing material (b); a monomer (c); and a polymerization initiator (d), in which the inorganic powder (a) is made of composite particles in which a layer of polysiloxane is formed on surfaces of substrate particles made of an inorganic material, and the fluoride ion releasing material (b) is at least one fluoride ion releasing material selected from the group consisting of ammonium fluoride, ammonium hydrogen fluoride, a metal fluoride, a polymer including, as a constitutional unit, a vinyl monomer having an acid fluoride group and a fluorine-containing phosphazene monomer.
Since the fluoride ion releasing dental composition of this invention provides dentine with a high cariostatic property over a long period of time by gradually releasing fluoride ions, it is suitably used as a dental adhesive material, a dental filling material, a dental resin used for forming an abutment, a pit and fissure sealant, a dental coating material (manicure), a dental cement and so on.
本发明提供了一种氟离子释放牙科组合物,包括无机粉末(a);氟离子释放材料(b);单体(c);其中无机粉末 (a) 由复合颗粒制成,在无机材料制成的基底颗粒表面形成一层聚硅氧烷、而氟离子释放材料(b)是至少一种氟离子释放材料,选自氟化铵、氟化氢铵、金属氟化物、聚合物(包括作为组成单元的具有酸性氟化基的乙烯基单体和含氟磷苯单体)。
由于本发明的氟离子释放牙科组合物通过逐渐释放氟离子,使牙本质在长时间内具有较高的防龋性,因此适合用作牙科粘合材料、牙科填充材料、用于形成基台的牙科树脂、窝洞和裂缝封闭剂、牙科涂层材料(美甲)、牙科粘结剂等。
