Abstract
Official abstract text for this publication.
The present invention provides polymerizable monomers represented by the following general formula (1) that are useful as dental materials. In the general formula (1), R a is a divalent C 6-9 aromatic hydrocarbon group or a divalent C 6-9 optionally bridged cyclic hydrocarbon group, R 1 and R 2 are each a hydrogen atom or a C 1-3 alkyl group, R 3 , R 4 , R 5 and R 6 are each a hydrogen atom or a hydrocarbon group, R 7 and R 8 are each a hydrogen atom or a methyl group, m and n are each independently 0 to 4, and R b and R c are each independently a C 2-6 linear alkylene or C 2-6 linear oxyalkylene group optionally substituted with a C 1-3 alkyl group or a (meth)acryloyloxymethylene group in place of a hydrogen atom.
First claim
Opening claim text (preview).
The invention claimed is: 1. A mobile tooth fixing material (βd) comprising a dental adhesive composition (d), the dental adhesive composition (d) including a polymerizable monomer (Ad) represented by the following general formula (1d), a polymerizable monomer (Bd) having at least one acidic group in the molecule, a photopolymerization initiator (Cd), and a flexible filler (Dd): wherein R ad is a divalent C 6-9 aromatic hydrocarbon group or a divalent C 6-9 optionally bridged cyclic hydrocarbon group, R 1d and R 2d are each a hydrogen atom or a methyl group, R 3 , R 4 , R 5 and R 6 are each a hydrogen atom or a hydrocarbon group, n and m are each independently an integer of 0 to 4, and R b and R c are each independently a C 2-6 linear alkylene or linear oxyalkylene group optionally substituted with a C 1-3 alkyl group or a (meth)acryloyloxymethylene group in place of a hydrogen atom. 2. The mobile tooth fixing material (βd) comprising the dental adhesive composition (d) according to claim 1 , wherein the filler(s) (Dd) includes a filler including a polyurethane. 3. The mobile tooth fixing material (βd) comprising the dental adhesive composition (d) according to claim 2 , wherein the polyurethane is a crosslinked polyurethane having ethylenic double bonds. 4. The mobile tooth fixing material (βd) comprising the dental adhesive composition (d) according to claim 1 , wherein the dental adhesive composition (d) only contains the photopolymerization initiator (Cd) as a polymerization initiator.
