Abstract: PURPOSE: To obtain the subject pasty dental material, comprising a polymerizable organic bonding agent and a finely divided filler, polishable to a high gloss, capable of fulfilling aesthetic requirements of a dental working material and having good physical properties and a sufficient transparency. CONSTITUTION: This pasty dental material comprises an Al-containing organopolysiloxane composed of a unit represented by formula I, a unit represented by formula II (R is a 1-6C alkyl bonded to an acrylate or a methacrylate, etc.) and/or a unit represented by formula III (R is a 1-3C alkyl or phenyl) and, in all the cases, units represented by formulae IV to V (R is a 1-5C alkyl or phenyl) used as a filler in the pasty dental material, comprising a polymerizable organic bonding agent and the finely divided filler and hardenable into a mass polishable to a high gloss in the presence of an initiator. Free atoms of O bonded to Si and Al are saturated with St or Al of the same or different units at (3:1) to (100:1) ratio of Si in the unit represented by formula I:Si in the units represented by formulae II to III and (2:1) to (200:1) ratio of Si in the units represented by formulae I to III:Al in the unit represented by formula IV.
