Abstract:

Methods are disclosed for forming a metal substructure that will subsequently be overcoated with ceramic layers to create a dental restoration. The methods involve the steps of providing a metal powder and applying the metal powder to a die and sintering the metal powder to form a solid structure that may be used as a coping. The application of the metal powder is done in a controlled fashion while minimizing the amount of necessary handwork. These application methods include: (a) alternatingly applying an adhesive and a metal powder to the selected portion of the die surface; and (b) forming the metal powder into a viscous slurry or slip and then dipping the die therein or spraying or pouring the slurry or slip onto the selected portion of the die surface.
