Chemically-curing type glass ionomer cement
View Patent ↗This invention provides quality and safe chemically-curing type GIC that solves all the disadvantages of light-curing type GIC, and has mechanical strength not lower but higher than that of light-curing type GIC and, in addition to this, the original features and advantages of GIC. The chemically-curing type glass ionomer cement according to the present invention includes porous and particulate hydroxy apatite that has a means diameter of not less than 0.6 μm and less than 100 μm and a large specific surface, and is added and mixed into the glass ionomer cement.
1. Chemically-curing type glass ionomer cement comprising porous and particulate hydroxy apatite that has a mean diameter of not less than 0.6 μm and less than 100 μm, and is added and mixed thereinto.
2. Chemically-curing type glass ionomer cement comprising porous and particulate hydroxy apatite that has a mean diameter of not less than 0.6 μm and less than 100 μm, and is added and mixed thereinto, wherein ultra-fine hydroxy apatite particles are adhered on the surface of said hydroxy apatite.
3. The chemically-curing type glass ionomer cement according to claim 1 , wherein the glass ionomer cement includes glass powder for glass ionomer cement, and the amount of the added and mixed hydroxy apatite is 5.0 to 35% by weight relative to this glass powder.
4. The chemically-curing type glass ionomer cement according to claim 1 , wherein the glass ionomer cement is adapted for dentistry.
5. The chemically-curing type glass ionomer cement according to claim 1 , wherein the glass ionomer cement is adapted for bone therapy in medicine and veterinary medicine fields.
6. The chemically-curing type glass ionomer cement according to claim 1 , wherein the glass ionomer cement is adapted for bone tissue restoration or regeneration.
7. A method comprising:
performing dentistry using the chemically-curing type glass ionomer cement according to claim 1 .
8. A method comprising:
performing bone therapy in medicine or veterinary medicine fields using the chemically-curing type glass ionomer cement according to claim 1 .
9. A method comprising:
performing bone tissue restoration or regeneration using the chemically-curing type glass ionomer cement according to claim 1 .
