Abstract
Abstract Enclosed are devices and methods for forming a denture in-situ in the mouth of a dental patient. An impression of the gums is made in an impression material through a spacer in a tray holding false teeth. The tray with the impression therein is removed from the mouth, the spacer removed and the top surface of the teeth exposed to provide a former into which liquid curable dentureforming material is then placed. The resulting assembly is then inserted into the mouth where pressure is applied and the resin cures to form the denture which is thereafter separated from the former which comprises the tray and impression material.
