Impression materials with improved rheological properties

Abstract

The invention relates to a multi-component system for producing a dental impression material, comprising in two or more separate components: i) one or more crosslinkable (co)polymers, ii) one or more components of a crosslinker system for crosslinking the crosslinkable (co)polymers, and iii) one or more fillers, wherein the multi-component system comprises at least one platelet-shaped filler, wherein the platelet-shaped filler has a first form factor F1=Dortho/Dmax in the range of 0.3 to 1.0 and a second form factor F2=Dmax/H of 3 or more, wherein Dmax is the maximum platelet diameter in the platelet plane, wherein Dortho is the largest platelet diameter orthogonal to Dmax in the platelet plane, and wherein H is the average platelet thickness orthogonal to the platelet plane.
