Method of making dental restorations and product thereof

Abstract

Abstract A restoration is made using an alloy of approximately 80 percent Ni - 20 percent Cr employing conventional casting techniques heretofore used with precious metals. After the casting has been cleaned it is heated under vacuum commencing at 1,400*- 1,500*F. and increasing gradually to approximately 1,950*F. The vacuum is released and the casting cooled -- a grayish blue colored compound forming on the surface. Porosities and casting defects may be conveniently repaired using ceramic gold paste. The metal may be soldered, to other metal members, whether of the same alloy or gold or any other conventional metal. Porcelain is then applied, again using conventional techniques. The product is characterized by the very good bond of porcelain to metal, extreme dimensional accuracy and relatively low cost of metal.
