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 or tooth segments from the supporting plate or to exactly put back the denture model or individual denture model segments 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 reduced by approximately 4/5 and 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.
