With scanning electron micrographs and semiquantitative x-ray analysis, the role of gallium in alloy-porcelain bonding was studied. The insight gained from this study should be of interest to both dentists and laboratory technicians making ceramometal restorations.
The results of this study suggest that the strengthening of aluminous porcelain with Sn-plated Pt is an effect of (1) a chemical interaction involving diffusion and dissolution of Sn-oxide in the glass phase of the porcelain and (2) a better wetting of te Sn-plated substrate by the porcelain. This conclusion supports and confirms the earlier hypothesis of McLean and Sced.
A technique for repairing the anterior region with use of aluminous porcelain-bonded-to-platinum-foil has been described. This technique produces a strong replacement and maintains the esthetic appearance of the original prosthesis.
A new method of attaching porcelain to precious metals using tin oxide coatings is described. Platinum foil is bonded to aluminous porcelain and forms an inner protective skin, thereby reducing the formation of microcracks and increasing the strength of the crown. An improvement in translucency of the crown is obtained by using thick layers of porcelain, and the technique still allows the use of a porcelain butt fit at the critical labiocervical margin.
