DENSIFICATION OF DENTAL PORCELAIN

¹ York, Pensylvania

Three different methods, capable of producing density in artificial porcelain teeth have been advanced. To the user, all of these systems provide better looking, stronger, and more useful porcelains than were previously available. Each of the methods has its own advantages and disadvantages. Vacuum firing produces excellent density and a fairly stable porcelain, but does not lend itself to mechanization and is, therefore, rather expensive as a manufacturing process. Diffusible atmosphere firing, at present, offers no technical or economic advantage over vacuum firing. Pressure methods are capable of equivalent density, but at the cost of thermal stability since they do not avoid the formation of bubbles but merely pressurize existing bubbles into the smallest possible dimensions. Nevertheless, this method is economical and of value in producing teeth for certain uses.
