ABSTRACT:
An alloyed metal dental prosthetic device, such as a coping, of an alloy dental reconstructive element, is formed from a liquid phase sintered powdered metal alloy at elevated temperatures of about 1000.degree.-1300.degree. C. under a high level of vacuum of about 10 to 1000 microns of Hg. A special oven is devised which will achieve this high level of vacuum in a rapid efficient manner. The resultant metal prosthetic device has the density of at least that found in commercial cast prosthetic devices.
