ABSTRACT:
The present invention is directed to a method for developing a bond having a shear strength in excess of 1200 psi between dental cements and dental appliances fashioned from glass-ceramic materials. The inventive method consists of contacting the fitting surface of the appliance with an etchant in flowable gel form at a temperature below about 150.degree. F., while protecting the exterior surface of the appliance. Subsequently, a silane solution followed by a dental cement is applied to the etched surface and cured in place.
