ABSTRACT:
A stanchion assembly is adjustably supported in spaced relationship over an edentulous area of a negative dental impression. A dental cast formed from the impression includes an edentulous portion replicating the edentulous area. The edentulous portion is made detachable from the cast and has a thickness determined by said space provided. The assembly includes a parting plate removable from the cast.
