Shear bond strengths of a ceramic system to alternative metal alloys

The success of metal-ceramic restorations is influenced by the compatibility between base metal alloys and porcelains. Although porcelain manufacturers recommend their own metal systems as the most compatible for fabricating metal-ceramic prostheses, a number of alloys have been used. Purpose This study evaluated the shear bond strength between a porcelain system and 4 alternative alloys.Two Ni-Cr alloys: 4 ALL and Wiron 99, and 2 Co-Cr alloys:...
