Abstract
A series of ceramic ingots is provided in which each ingot in the series, referred to as base ingots, has a shade corresponding to a different shade of a shade guide. The number of differently shaded base ingots is less than the total number of shades associated with the shade guide. A base ingot is selected from the series having a shade of a value at least as high as a shade associated with a patient's tooth. If the base ingot shade matches the patient's tooth, a restoration made with the selected base ingot can be glazed as is; otherwise the dental restoration is stained with a stain having a lower value than the selected base ingot to match the tooth. Thus, the total different number of ingot shades needed in inventory is reduced but without requiring staining in every case.
