    摘要： Dental restorations such as crowns, are made from lithium silicate glass ceramic that is heated and pressed onto a metal substrate, the latter being shaped to an impression or scan of the area of the mouth to receive the restoration. The metal substrate is made from an alloy selected to exhibit a coefficient of thermal expansion which is slightly greater than the CTE of the lithium silicate. In a preferred embodiment, the CTE of the lithium silicate glass ceramic is in the range of 11.5 to 12.5 and the alloy is selected to have a CTE of 12 to 13.5. A palladium tin alloy provides that CTE in the preferred embodiment.

    摘要： A new investment material for the pressing loss wax technique for dental glass ceramics. It has been found that the addition of fillers to a magnesium phosphate investment, specifically metal oxides with elevated melting points ranging from 1800 to 2800° C., provides a protection barrier against the reaction between the high alkaline content of the glass ceramic and the investment during the pressing process in the range of 800 to 950° C. Specifically, it has been found that the addition of aluminum oxide of about 2 to 5 percent of the total dry mix in combination with any of the zirconium oxide, yttrium stabilized zirconium, titanium dioxide and boron nitride in proportions of about 3.5%, enhances the barrier against a surface reaction and improves the thermal properties of the investment.

    摘要： A method of fabricating a one crystalline phase lithium silicate glass ceramic and the manufacture of machinable blocks for dental appliances using a CAD/CAM device. The resulting glass ceramic contains a thermodynamically stable lithium silicate crystal through each of the steps of the process due to its specific material formulation.
