A hydrophilic cross-linked ionic polycaprolactone polymer composition formed by the process of subjecting hydrophobic caprolactone or a hydrophobic caprolactone monomer to a source of ionizing radiation selected from the group consisting of an Electron Acceleration (E beam), Gamma II, Cobolt, X-ray or a source of UV radiation to form an ionic cross linked polycaprolactone polymer consisting of a soluble component part and an insoluble component part in a gel fraction % of soluble to insoluble parts, adjusting the duration of ionizing radiation and/or the intensity of the radiation until the concentration of the soluble component part is above at least about 65% by weight of the cross linked polymer wherein the cross linked polycaprolactone polymer is converted from a hydrophobic to a hydrophilic state. A coating of the hydrophobic polycaprolactone when in contact with water forms a boundary layer with very low contact angle.

Hydrophilic polymer composition and method of forming a hydrophilic polycaprolactone

A dental material composed of hydrophilic polycaprolactone formed by the process of exposing a hydrophobic caprolactone to ionizing irradiation from a radiation source selected from the group consisting of an Electron Acceleration (E beam), Gamma II, Cobolt, X-ray or a source of UV radiation to form a cross linked polycaprolactone composition consisting of two distinct phases one of which is soluble and the other non-soluble, and adjusting the duration of ionizing radiation and/or the intensity of the radiation to cause the concentration of the soluble phase to be above at least about 65% by weight of the cured polymeric composition whereby the hydrophobic caprolactone becomes hydrophilic.

Dental material and method

The dental filler material is formed from a selection of one or more finely divided inorganic particles of, barium containing glass or zeolite crystals with up to 100% of such particles having a coating thereon of a polymerized acrylate containing monomers or oligomers. The dental composite is formed using the dental filler material and a methacrylate based polymeric resin binder system.

Dental filler material containing zeolite for dental composite and

The method of the present invention involves fabricating a cast metal framework from a non-precious metal alloy containing nickel, electroplating a thin film of gold over a predetermined surface area of the framework, distributing finely divided gold particles of varying size about the electroplated surface and firing successive layers of porcelain over the predetermined surface area.

Method of manufacturing a metal ceramic dental restoration

The dental material of the present invention comprises a polymerizable binder, a polymerization agent and an additive comprising finely divided particles of muscovite mica in a range of from about 1 to 20 percent by weight of the dental material for direct dental filling and restoration applications and in a range of from about 1 to 30 percent for cosmetically treating the surface of a tooth as a veneer or paint-on.
