  • Publication number: 20130213549
    Abstract: The present invention is directed toward an adhesive for and a method for bonding artificial plastic teeth to a denture base. The adhesive employs a number of adhesion promoter monomers, dimers or oligomers and a cure package, as well as methyl acetate as a solvent. The method according to the invention includes exposing a plastic tooth to the adhesive and allowing the plastic to soften (not dissolve). The adhesion promoter chains infiltrate the plastic tooth matrix, such that upon curing a secure bond is formed.

  • Publication number: 20130209966
    Abstract: An integrated dental porcelain system for making dental prostheses and restorations is provided. The system includes three universal major components: a) opaque porcelain composition; b) pressable dentin ingot; and c) veneering porcelain composition that can be used interchangeably for making restorations. Techniques for making the prostheses and restorations include porcelain fused-to-metal (PFM), press-to-metal (PTM), and either pressed and/or machined all-ceramic methods. The system uses both a hand-layering of veneering porcelain (PFM technique) and a hot-pressing process (PTM and all-ceramic technique) to fabricate the prostheses and restorations.

  • Publication number: 20130209955
    Abstract: A device includes a connecting end and a working end. Device has an internal fluid passageway and a bend area. The fluid passageway has a discharge opening or hole, which opening is positioned or located substantially away from the bend area, such that the discharge opening and upstream portions of the passageway will remain unaffected, substantially unaffected, or selectively affected by any deformation thereof due to the bending procedures employed to make the other portions of the tool, such as those conventionally involved in fabricating the bend area.

  • Publication number: 20130165020
    Abstract: A method of processing a surface of a metallic implant, such as a dental implant, to provide a desirable surface roughness, comprising subjecting the metallic implant to blasting with particles of one or more titanium oxides, including at least one non-stoichiometric titanium oxide, the particles having a compact morphology and a particle size in the range of from 1 to 300 ?m. The resulting implant surface showed unexpectedly high retention strength after implantation in bone.

  • Patent number: 8466211
    Abstract: A one-part, self-etching dental adhesive having improved performance such as adhesion performance with a simple one-coat application, without the need of separate acid-etching, a priming pre-treatment, or bonding step. The invention provides such improvements due to a function of the pH balance of the system in combination with an acid stable photoinitiating system. More specifically, the performance and pH balance is achieved through the employment of a hydrolytically stable, acidic, high-strength adhesive monomer (such as PENTA), with a stable, bifunctional, hydrophilic monomer (such as AHPMA) that yields greater crosslinking.

  • Patent number: 8426491
    Abstract: Dental compositions comprising a polymerizable compound, filler system of nanometer-sized silica particles, and polymerization system capable of being activated by light are provided. The compositions further contain a solvent such as a mixture of 1-butanol and acetone and may contain water. The nanometer-sized silica particles, having an average particle size of about 1 nm to about 100 nm, are uniformly dispersed within the resin. The compositions can be applied as a polish, sealant, bleach guard, or other coating material to the surfaces of dental restorations and teeth. Self-etching and non-self-etching compositions are provided. The cured coating forms a protective, durable film that enhances the shine and luster of the restorations and teeth.
