Method for adjusting or improving the usage properties of flowable dental composites containing fillers(s) and glass filler(s), in which i) at least one prepolymer filler A1 is added, ii) the content of component A1 is varied, iii) at least one hydroxy-functionalised additive A2 having a molecular weight < 250 g/mol is added, the additive A2 being of formula H-Y-Z, where: Y = -O-, -S-, -CO-, -OSi(OR 1) 2 -, -OE Z = H, OH, SH, NH 2, COOH, COOR 2 E = -C n H m O p - R 1 = H, C 1 -C 4 -alkyl R 2 = C 1 -C 15 -alkyl, C 2 -C 14 -alkyl interrupted by one or more O-atoms, n = 2 to 5 m = 4 to 10 p = n, a maximum of 5 % by weight each of the at least one additive A1 and A2, based on the total composition of the dental composite, being added, iv) a measurand IK [Force, gram] for adhesiveness and a measurand IG [Force, gram] for texturing or plasticity or consistency are being related to each other, - the value IG for texturing/plasticity/consistency being determined from the effort of force upon passage through a defined constriction or from the force opposing a predetermined penetration depth of a measuring stamp, and - the value IK for adhesiveness being determined from the pull-off force upon pull-off of the measuring stamp from the composite surface, which has been pressed onto the sample with a defined force, and thereafter v) an optimised proportion of glass filler(s) and prepolymer filler is determined, the quotient of the value IG for texturing/plasticity/consistency divided by the adhesiveness value IK functioning as measurand for quality evaluation. i) at least one prepolymer filler A1 is added, ii) the content of component A1 is varied, iii) at least one hydroxy-functionalised additive A2 having a molecular weight < 250 g/mol is added, the additive A2 being of formula H-Y-Z, where: Y = -O-, -S-, -CO-, -OSi(OR 1) 2 -, -OE Z = H, OH, SH, NH 2, COOH, COOR 2 E = -C n H m O p - R 1 = H, C 1 -C 4 -alkyl R 2 = C 1 -C 15 -alkyl, C 2 -C 14 -alkyl interrupted by one or more O-atoms, n = 2 to 5 m = 4 to 10 p = n, a maximum of 5 % by weight each of the at least one additive A1 and A2, based on the total composition of the dental composite, being added, Y = -O-, -S-, -CO-, -OSi(OR 1) 2 -, -OE Z = H, OH, SH, NH 2, COOH, COOR 2 E = -C n H m O p - R 1 = H, C 1 -C 4 -alkyl R 2 = C 1 -C 15 -alkyl, C 2 -C 14 -alkyl interrupted by one or more O-atoms, n = 2 to 5 m = 4 to 10 p = n, a maximum of 5 % by weight each of the at least one additive A1 and A2, based on the total composition of the dental composite, being added, iv) a measurand IK [Force, gram] for adhesiveness and a measurand IG [Force, gram] for texturing or plasticity or consistency are being related to each other, - the value IG for texturing/plasticity/consistency being determined from the effort of force upon passage through a defined constriction or from the force opposing a predetermined penetration depth of a measuring stamp, and - the value IK for adhesiveness being determined from the pull-off force upon pull-off of the measuring stamp from the composite surface, which has been pressed onto the sample with a defined force, and thereafter - the value IG for texturing/plasticity/consistency being determined from the effort of force upon passage through a defined constriction or from the force opposing a predetermined penetration depth of a measuring stamp, and - the value IK for adhesiveness being determined from the pull-off force upon pull-off of the measuring stamp from the composite surface, which has been pressed onto the sample with a defined force, and thereafter v) an optimised proportion of glass filler(s) and prepolymer filler is determined, the quotient of the value IG for texturing/plasticity/consistency divided by the adhesiveness value IK functioning as measurand for quality evaluation.
