Adhesive bonding to teeth of orthodontic brackets and the like

摘要: Orthodontic brackets and the like are adhesively secured to teeth by means of a self-curing thixotropic acrylic ester monomer composition wherein has been made through inclusion fumed silane treated silica or monomers have two more active groups, compositions prior curing having viscosity about 85,000 cps 4,385,000 cps. Prior adhering orthodontic bracket other device tooth surface, surface is acid-etched, rinsed dried. The thixotropic-activated then applied just placing on tooth. activated application blending substantially equal proportions containing monomer, silica, amine activator with peroxide catalyst. adhered mix left undisturbed while being kept relatively dry until hardened. Arch-wires may be bracket.
