Method for adjusting or improving or optimizing the usage properties of filler(s)-containing, flowable dental material, which involves relating to at least one measuring value representing the tackiness to at least one measuring value representing the texturing or plasticity or consistency. Flowable, usage-optimized, usually non-polymerized dental composites contain, as fillers, at least one glass filler and at least one filler from the group of chipped polymers or pre-polymer fillers based on ground polymer that is pre-polymerized together with inorganic particles,and, as additive(s),at least one compound represented through formula H—Y—Z (I),where: Y=—O—, —S—, —CO—, —OSi(OR1)2—, —OE Z=H, OH, SH, NH2, COOH, COOR2 E=—CnHmOp- R1=H, C1-C4-Alkyl R2=C1-C15-Alkyl, interrupted by one or more O atoms. C2-C14-Alkyl, n=2 bis 5 m=4 bis 11 p=n.
