Abstract: The present invention provides for a device for use with denture models comprised of a supporting plate having upper and lower sides, and having at least one opening located on the upper side. An area for receiving retention pins is provided on the upper side of the supporting plate, the opening being located in the area for receiving the retention pins. At least one fitting head is provided where the fitting head is longer than the depth of the opening. A lift off plate is also provided having upper and lower sides and having a surface capable of contacting the fitting head.

Abstract: The invention relates to a supporting plate with retention pins for a denture model which makes it possible to repeatedly remove the denture model or individual jaw tooth segments from the supporting plate or to exactly put back the denture model or individual denture model segment on the supporting plate without wearing out by friction the material of the model. This is achieved by means of a supporting plate for a denture model in which the height of the outer side wall of the arc-shaped impression on the supporting plate is lower in height relative to the inner side wall, and where the outer side wall is vertical or diagonal. Furthermore, wall segments having different contours make it possible to easily and rapidly classify the removed denture model segments.
