title: Soldering ceramic-metal restorations.
abstract: This is a technique for soldering ceramic-metal restorations in a vacuum-fired furnace. Care must be exercised to prevent adherence of the flux to the porcelain surfaces. Low-heat solders have been used, but they do not flow any better and may result in a weak union. The various colors of impression plaster to form the key for removal of the assembly are used to prevent softening and distortion of the individual units. There are several techniques described in assembling and soldering ceramic-metal restorations. This technique is direct, accurate, and easily accomplished.
