| Zusammenfassung: | This invention relates to gold-based dental alloys for use in dental restorations.
Dental alloys are provided having a coefficient of thermal expansion in the range from about 8 to about 18×10/° C. in the temperature range of 25-500° C. and melting temperatures above about 800° C. but below about 1500° C. The alloys contain gold in combination with a small amount of chromium and/or tantalum. Other elements may also be included with the gold and chromium and/or tantalum to provide the necessary forming, melting, and mechanical properties required to manufacture the desired dental restoration. |
