US Patent:

20070009448, Jan 11, 2007

Filed:

Feb 23, 2006

Appl. No.:

11/360979

Inventors:

John Kanca - Middlebury CT, US

International Classification:

A61K 8/89

US Classification:

424049000

Abstract:

Etching compositions, curable compositions, packaged products and methods of use for the treatment of bone substrate, i.e., teeth, are described. The etch solutions generally include an aqueous acidic solution with an ethylenically unsaturated monomer and a silane. The methods of the invention provide the ability to modify a bone or bone-like surface so that the curable composition, such as an adhesive resin, can be used in combination with a restorative material.

Appl. No.:

11/360980

Inventors:

John Kanca - Middlebury CT, US

International Classification:

A61K 8/19
A61K 8/81

US Classification:

424049000

Abstract:

Etching compositions, curable compositions, packaged products and methods of use for the treatment of bone substrate, i.e., teeth, are described. The etch compositions generally include a gelling agent, an inorganic acid, an organic acid and either a solvent, a surfactant or mixtures thereof. The curable composites include reactive monomers and crosslinking agents that are effective to adhere to the surface of the treated substrate. The methods of the invention provide the ability to modify a bone or bone-like surface so that the curable composition, such as an adhesive resin, can be used in combination with a restorative material.

Appl. No.:

11/360978

Inventors:

John Kanca - Middlebury CT, US

International Classification:

A61K 6/10

US Classification:

523109000

Abstract:

Three part bonding compositions that include an etching solution, a preparative solution, and a curable composition, as well as packaged products and methods of use for the treatment of bone substrate, i.e., teeth, are described. The etch solutions generally include an inorganic acid, an organic acid, an ethylenically unsaturated functional monomer and, optionally a solvent, and water. The preparative solutions generally include an ethylenically unsaturated functional monomer, at least one polyethylenically unsaturated functional crosslinking monomer, a photo initiator, and at least one solvent. The curable composites include reactive monomers and crosslinking agents that are effective to adhere to the surface of the treated substrate. The methods of the invention provide the ability to modify a bone or bone-like surface so that the curable composition, such as an adhesive resin, can be used in combination with a restorative material.

Filed:

Jan 13, 1984

Appl. No.:

6/570380

Inventors:

John Kanca - Middlebury CT

International Classification:

A61C 500

US Classification:

433229

Abstract:

A light delivery device and resin curing method to facilitate access to and improved curing of composite material applied, for example, to posterior teeth cavity preparations. The light delivery or photocuring device basically comprises a fibre optic wand having a slender rod shaped or needle like fibre optic tip or end cap. Improved photocuring may be effected with the light transmitting fibre optic tip being placed and/or oscillated juxtaposition with the light curable resin deposited within a tooth cavity.
