Abstract
A dental impression material includes: a base material paste that includes an alginate and water; and a curing material paste that includes a gelling reagent and a poorly water-soluble liquid compound. A viscosity of 10% aqueous solution of the alginate at 20° C. is 5 mPa·s or more and 90 mPa·s or less.
Claims1
A combined dental impression material comprising:
- a base material paste that includes a first alginate, a second alginate and water;
- and
- a curing material paste that includes a gelling reagent and a liquid compound, wherein the liquid compound has a solubility of 5 grams or less in 100 g of water at 20° C.
- a viscosity of 10 mass % aqueous solution of the first alginate at 20° C. is 5 mPa·s or more and 90 mPa·s or less and a viscosity of 1 mass % aqueous solution of the first alginate at 20° C. is 0.1 mPa·s or more and 2 mPa·s or less,
- and wherein
- a viscosity of 1 mass % aqueous solution of the second alginate at 20° C. is 100 mPa·s or more and 400 mPa·s or less.
