Abstract
Disclosed herein is an improved tray for use in producing a denture either in-situ or by use of a model of the patient's mouth. The tray comprises a basic tray of disposable material approximating the shape of either the palate or the lower gums and having inner and outer wall portions integral therewith and forming a trough defining a gum receiving portion with a U-shape opening in the trough mounting, means for mounting a plurality of artificial teeth approximating the teeth found in either the upper or lower portion of the mouth, the mounting means having a flange portion made of dental acrylic which rests on the sides of the trough adjacent the U-shaped opening with the plurality of the teeth extending through the opening. The process of producing the denture comprises placing the tray in to a patient's mouth, pressing the deformable walls of tray against the surfaces of the patient's mouth to approximate the shape of the upper or lower part of the mouth, withdrawing the shaped tray; placing a moldable acrylic base denture forming resin in the tray; pressing the tray holding the resin against the portion of the patient's mouth until the resin cures in-situ to conform to the shape of the adjacent surfaces of the patient's mouth, withdrawing the tray containing the cured resin from the patient's mouth, and separating the tray from this cured resin, whereby the denture remains comprising the cured resin and the attached flange and artificial teeth.
