摘要:
The use of microporous inorganic fillers in polymerizable compositions, in particular in the dental field, characterized in that the fillers have(a) an average particle size of 0.5 to 50.mu.,(b) a BET-surface area of at least 200 m.sup.2 /g,(c) a pore volume of 0.7 to 5 ml/g and(d) a pore diameter of 10 to 50 nm.Fillings made therefrom are smooth and easy to polish.
摘要:
The adhesion of resin material to the solid substance of the tooth and to metals and metal alloys, for example, dental alloys, can be improved with a photo-polymerizable formulation containing hydroxyalkyl(meth)acrylates, urethanedi(meth)acrylates and, if applicable, esters of aromatic polycarboxylic acids possessing methacryloyloxy groups.
摘要:
The invention relates to formulations for use as an adhesive component for treatment of tooth hard substance, a process for their preparation and their use.
摘要:
A formulation for use as a dental adhesive in the treatment of the hard tooth substance, to provide enhanced bonding between dental restoration material and the enamel and dentine of the tooth. The formulation contains glycerol di(meth)acrylate, volatile solvent, photo-initiator and, optionally, usual additives and fillers.
摘要:
The invention relates to urethane acrylates and urethane methacrylates containing cyclic carbonate groups, and use thereof in dental materials and lithographic plates.
摘要:
Polymerizable aromatic carboxylic acids and carboxylic acid anhydrides with cyclic carbonate groups which are useful for improving adhesion of synthetic dental filling materials.
摘要:
A condensation product of a hydroxy(meth)acrylate compound corresponding to the formula ##STR1## in which R.sub.1 is hydrogen or methyl, A is a trivalent aliphatic residue with 3 to 15 C-atoms which is unsubstituted or substituted with OH groups and optionally contains up to 5 ether bridges, and an aromatic carboxylic acid anhydrides compound of the formula (II) or an aromatic carboxylic acid anhydride chloride compound of the formula (II) ##STR2## in which Ar is a benzene ring or a naphthalene ring, n is 1 or 2, and m is 0, 1 or 2. The condensation product has a molar mass of 300 and to 10,000 daltons. The condensation product is useful as an adhesive to bond dental filling materials to teeth.
