Abstract
A denture is constructed on a cast of the denture-bearing tissues. Before this cast can be made, an impression, or negative likeness, of these tissues is obtained. The impression material, which is held against the tissues and supported by an impression tray, exhibits plastic flow in the initial stages and then subsequently hardens or sets. Either plaster of Paris or model stone is then poured into the impression to form the cast, or positive likeness, of the denture-bearing tissues.
