Polymerizable dental components with improved usage properties, methods for adjusting the usage properties of polymerizable dental composites, and dental composites optimized according to said methods

摘要

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—, —OEZ=H, OH, SH, NH2, COOH, COOR2 E=—CnHmOp-R1=H, C1-C4-AlkylR2=C1-C15-Alkyl, interrupted by one or more O atoms. C2-C14-Alkyl,n=2 bis 5m=4 bis 11p=n.

1. Method for adjusting or improving or optimizing the usage properties of filler(s)-containing, flowable dental material, to which
i) at least one pre-polymer filler A1 is added; ii) the fraction of component A1 is varied; iii) at least one hydroxy function-containing additive A2 with a molecular weight
<250 g/mol is added wherebyadditive A2 is represented through formula H—Y—Z (I) where:Y=—O—, —S—, —CO—, —OSi(OR1)2—, —OEZ=H, OH, SH, NH2, COOH, COOR2 E=—CnHmOp—R1=H, C1-C4-AlkylR2=C1-C15-Alkyl, interrupted by one or more O atoms, C2-C14-Alkyl,n=2-5m=4-11p=n; iv) measuring a value IK (Force, g) representing the tackiness and measuring a value IG (Force, g) representing the texturing or plasticity or consistency are related to each other
whereby the IG value representing the texturing/plasticity/consistency is determined from the requisite force upon passage through a defined constriction or from the opposing force at a predetermined penetration depth of a measuring stamp, and/orwhereby the value IK presenting the tackiness is determined from the peeling force required to peel a measuring stamp, which has been pressed onto the sample with a defined force, off the surface of the composite; and v) an optimized ratio of at least one glass filler and pre-polymer filler is determined;
whereby the ratio of the IG value representing the texturing/plasticity/consistency divided by the tackiness value IK is used as a measuring parameter for assessment of the quality and; vi) the IG/IK ratio of the dental material is adjusted to from at least 1.3 to at most 5.6.
