Abstract:
The application relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler C, non acid-reactive filler A, Paste B comprising water, polyacid, complexing agent, non acid-reactive filler B, the mean particle size of non acid-reactive filler B being larger than the mean particle size of non acid-reactive filler A, the water content of the composition obtained when mixing Paste A and Paste B being below 20 wt.-%. The application also relates to a device for storing such a kit of parts and the use of the kit of parts and/or the device for preparing a dental cement, dental filling material, dental core build up material or dental root channel filling material.

Claim (Index 11):
The kit of parts of  claim 1 , being characterized as follows:\n Paste A comprising:\n water in an amount from 5 to 18 wt.-%; \n the acid-reactive inorganic filler C in an amount from 20 to 90 wt.-%, the acid-reactive inorganic filler C having a mean particle size in the range from 3 to 10 \u03bcm and being selected from metal oxides, metal hydroxides, hydroxyapatite, fluoroaluminosilicate glasses and mixtures thereof; and \n the non acid-reactive filler A in an amount from 1 to 50 wt.-%, the non acid-reactive filler A having a mean particle size in the range from 10 nm to 500 nm and being selected from silica, alumina, titania, zirconia and mixtures thereof; \n Paste B comprising:\n water in an amount from 7 to 20 wt.-%; \n the polyacid in an amount from 3 to 70 wt.-%; \n the complexing agent in an amount from 0.1 to 12 wt.-%; and \n the non acid-reactive filler B in an amount from 5 to 60 wt.-%, the non acid-reactive filler B having a mean particle size in the range from 1 to 10 \u03bcm and being selected from quartz, kaolin, silica, alumina, titania, zirconia and mixtures thereof; \n wt.-% with respect to the weight of the respective Paste A or Paste B, wherein neither Paste A nor Paste B comprising polymerizable component(s) in an amount above 1 wt.-% with respect to the weight of the composition obtained when mixing Paste A and Paste B.
