| titleOfInvention | Dental constructions and dental alloys |
| abstract | ABSTRACT OF THE DISCLOSURE The invention relates to dental constructions such as bridges, crowns and the like comprising a metal core and porcelain or other tooth simulating material bonded thereto. The metal core is an alloy having excellent physical properties for dental applications, having a fusion temperature with the range of about 2050° to 2250°F, a coefficient of expansion of from about 13.6 x 10-6 in/in/°C to about 13.8 x 10-6 in/in/°C, good corrosion resistance when compared with similarly cast gold or other commercial nonprecious metal dental alloys and good oxidation resistance. The alloy has as casted, a tensile strength of at least 90,000 p.s.i., an elongation of about 0.5 to 5.0%, a Rockwell C hardness within the range of about 25 to 33, and good bonding to porcelain. |
