BONDING GLASS-CERAMIC DENTAL PRODUCTS

摘要

The present invention is directed to a method for developing a bond having a shear strength in excess of 1200 psi (82.68 bars) 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 DEG F (65.56 DEG C), 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.
