摘要:
The present invention provides a method of luting a provisional prosthetic device to tooth structure using glass ionomer cement systems having reduced bulk shear adhesion. The invention also provides a kit for luting a prosthetic device to tooth structure. The kit contains at least three containers of glass ionomer luting cement compositions. The kit advantageously can be utilized for providing both a provisional and a permanent luting cement depending upon which components are admixed.
摘要:
Polymerizable compositions that include: (a) a cationically active functional group; (b) an initiation system capable of initiating cationic polymerization of the cationically active functional group; and (c) a filler composition that includes various radiopacifying fillers in an amount sufficient to render the polymerizable composition radiopaque. Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.

摘要:
Methods of using a dental composition having a photobleachable dye and an acidic component with a pKa of less than 4.5 are disclosed. The photobleachable dye is selected from the group consisting of aminoanthraquinone dyes, azo dyes, and combinations thereof. The aged color of the dental composition is substantially the same as the color of the dental composition immediately after hardening.
摘要:
Orthodontic adhesives and packaged articles including an orthodontic appliance having a base for bonding the appliance to a tooth are disclosed. In the packaged articles, an adhesive is on the base of the appliance, and a container at least partially surrounds the orthodontic appliance having adhesive on the base thereof.
摘要:
The invention provides a pretreatment method and primer that is applied directly to the hard tissue. The invention has particular utility for adhering to or coating sclerotic dentin and cervical enamel or for adhering to or coating hard tissue in a high humidity environment. The primer enables formation of extremely strong bonds to dentin. The method comprises the steps of: (a) applying to the hard tissue adhesively effective amounts of an acid and a water-dispersible film former comprising a polymer and (b) hardening the film former. Primer compositions are provided for use in this method, comprising a mixture of an acid and a film former comprising a polymer prior to hardening, the mixture being in the form of a film atop the hard tissue.
摘要:
Amide-functional polymers, and compositions including such polymers, are disclosed. The compositions, which optionally may be hardenable, are useful for treating a surface.
摘要:
Dental compositions are provided that can be delivered as a fine mist and that have the capability of undergoing an increase in viscosity in response to an increase in temperature. In a preferred embodiment, the compositions also have the ability to reverse their viscosity in response to a decrease in temperature.
摘要:
Thermally responsive compositions that include a thermally responsive viscosity modifier, a polymerizable component, and water are provided. The compositions, which optionally may be hardened, are useful for application to a surface of a body.
摘要:
The present invention features ionomer compositions containing nanozirconia fillers. The compositions can be used in a variety of dental and orthodontic applications, for example, as adhesives, cements, restoratives, coatings and sealants.
