A dental device for fabricating models comprising: a recessed tray having a base and inner and outer walls extending upwardly therefrom, said base having apertures extending therethrough in a predetermined pattern and a rear portion extending upwardly from the tray and having a pair of spaced, hollow cylindrical members at the end thereof, and a member mounted within the tray, having predetermined lower portions extending through the apertures in the base of the tray, a base, and an upwardly extending portion integrally engageable by the model which is formed within the tray wherein the model may be readily ejected from the tray by pressing on the lower projecting portions thereof.
Claim 3
Dependent Claim
65 words
A dental device in accordance with claim 1: the inner and outer walls of the tray comprise a plurality of ridges which extend upwardly from the base to permit accurate relocation of the model in the tray and wherein said ridges are parallel to adjacent ridges on the same wall but not to ridges on the opposite wall to prevent accidental dislocation of separated sections.
