Appeal No. 95-0992
Application 08/014,104
claim.
THE INVENTION
Appellant claims a method and kit for obtaining high bond
strength to a previously set dental amalgam (specification, page
3, lines 27-28). The method includes applying to the amalgam a
primer and an adhesive, where the primer includes an oxidant
which has an oxidation-reduction half-reaction electrode
potential which is greater than the absolute value of that of the
amalgam. The kit includes a primer which contains an oxidant
having an oxidation-reduction half-reaction electrode potential
greater than 0.8 volts. Claims 1 and 21 are illustrative and
read as follows:
1. A method for adhering to or coating a dental metal,
comprising the steps of:
applying to said dental metal adhesively effective amounts
of a primer composition and an adhesive, wherein said primer
composition comprises an exodant having an EE oxidation potential
greater than the absolute value of the EE reductant of said
dental metal; and
hardening said adhesive.
21. A kit for adhering to or coating dental amalgam,
comprising:
a primer comprising an oxidant having an EE oxidation
potential greater than 0.8 Volts; and an adhesive, wherein upon
hardening said adhesive is capable of providing an average
measured shear strength of at least 7 MPa between said adhesive
and dental amalgam.
