Shear Strength of the Composite Bond to Etched Porcelain

摘要: The shear bond strength of composite resin to porcelain was investigated optimize variables for bonding laminate veneers. Scanning electron microscopy initially used examine the surface configuration prepared under various conditions. A factorial experiment undertaken determine effects three different methods on both etched and non-etched porcelain. Composite bonded groups using (a) unfilled resin, (b) silane, (c) silane with dentin adhesive. results indicated a significant difference in groups, depending condition. For unetched samples, differences were obtained all However, group, there no between silane-with-dentin-adhesive groups. Porcelain etching significantly increased across main contributor values.
