Abstract
A granular, polymerizable composition which contains at least one polymerizable monomer and/or oligomer and a polymerization initiator and optionally an accelerator and at least 70% by wt. filler and additionally 0.5 to 28% by wt. dendrimer and which becomes flowable under compressive or shear stress. The composition can be packed in similar manner to amalgam and is particularly suitable as dental material or for the production of a dental material.
