  • Method for priming hard tissue
    Patent number: 4880660
    Abstract: A single phase aqueous solution containing water, a water-soluble film former (e.g., 2-hydroxyethylacrylate) and a salt of an acid (e.g., calcium trifluoroacetate) is used as a primer for adhering to or overcoating hard tissue such as tooth dentin.
    Type: Grant
    Filed: August 28, 1987
    Date of Patent: November 14, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Steven M. Aasen, Joel D. Oxman
  • Organic fluoride sources
    Patent number: 4871786
    Abstract: Organic fluoride sources comprising a tetrafluoroborate salt and capable of releasing fluoride ions into dentition in order to provide inhibition and/or prevention of dental caries are disclosed. A method of releasing fluoride ion into dental tissue is also disclosed.
    Type: Grant
    Filed: October 3, 1988
    Date of Patent: October 3, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Steven M. Aasen, Joel D. Oxman, F. Andrew Ubel, III
  • Coated abrasive binder containing ternary photoinitiator system
    Patent number: 4828583
    Abstract: Coated abrasive binders made from a photocurable addition-polymerizable composition containing a free-radically-polymerizable monomer and a photoinitiator system containing (i) an arylidonium salt, (ii) a sensitizing compound, and (iii) an electron donor having an oxidation potential that is greater than zero and less than or equal to that of p-dimethyoxybenzene (1.32 volts vs. S.C.E.). The binders cure rapidly and deeply under ultraviolet or visible light, even when filled with large amounts of mineral grain or with coarse grades of minerals.
    Type: Grant

    Date of Patent: May 9, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Joel D. Oxman, F. Andrew Ubel, III, Eric G. Larson
  • Coated abrasive binder containing ternary photoinitiator system
    Patent number: 4735632
    Abstract: Coated abrasive binders made from a photocurable addition-polymerizable composition containing a free-radically-polymerizable monomer and a photoinitiator system containing (i) an arylidonium salt, (ii) a sensitizing compound, and (iii) an electron donor having an oxidation potential that is greater than zero and less than or equal to that of p-dimethoxybenzene (1.32 volts vs. S.C.E.). The binders cure rapidly and deeply under ultraviolet or visible light, even when filled with large amounts of mineral grain or with coarse grades of minerals.

  • Method for priming hard tissue
    Patent number: 4719149
    Abstract: An acid and a water-soluble film former are used as a primer for hard tissue (e.g., dentin). The acid has a pK.sub.a less than or equal to that of phenol and the acid and its calcium salt(s) are soluble in the film former. The primer is free of adhesively detrimental quantities of calcium salts that are not soluble in the film former.
