摘要： Plastic orthodontic brackets having an adherent acrylic adhesive primer layer on the bonding surface thereof are disclosed, as well as methods of making such brackets. Primed plastic orthodontic brackets which are shelf-stable and which obviate the need for the chairside primers commonly used by clinicians are contemplated. In a method of the present invention, a solvating mixture of solvents and acrylic monomers is applied to the bonding surface of a plastic bracket and allowed to attack (solvate) and diffuse into the plastic substrate. Thereafter the bracket is heated to volatilize the solvents and lower molecular weight monomers to thereby leave a coating or layer of acrylic material which is predominantly monomeric and is at least partially embedded in the plastic bracket. This coating acts as a primer for acrylic cements and enhances the bonding between the plastic orthodontic bracket and the tooth surface to which it is applied using acrylic adhesive cements which are themselves well known in the art.

摘要： An orthodontic bracket has an archwire slot adapted to receive an archwire therein and comprises a core and an overmolded polymeric cover that covers the core. The polymer of the overmolded polymeric cover is cross-linked. The thickness and the cross-linked density of the cover are sufficient to limit chemicals found in an oral environment from passing through the cover during treatment. In an embodiment, the core comprises a polycarbonate and the cover comprises a polyurethane. A method of making an orthodontic bracket comprises providing a core and overmolding a polymeric cover over at least a portion of the core and cross-linking the polymer of the polymeric cover. In another embodiment, a method of molding an orthodontic bracket comprises injecting a first polymer into a mold cavity to form a polymeric core and injecting a second polymer into the mold cavity to form an overmolded polymeric cover over the core.

摘要： Orthodontic appliances (brackets) having a pre-applied or factory applied adhesive thereon presenting a non-tacky surface are described. The brackets, which may be plastic, metal or ceramic, have a bonding base surface to which an appropriate adhesive composition is pre-applied. The adhesive, which is uncured and generally presents a tacky outer surface, is protected from deterioration or disturbance by the attachment or adherence of particles, which may form a layer, on the outer surface of the adhesive, thereby presenting a non-tacky surface. Also included are articles consisting of a container with a cover and an orthodontic bracket having pre-applied adhesive received in the container. The adhesive on the bracket in the container presents a non-tacky surface by virtue of a layer of particles secured to the otherwise tacky adhesive surface.
