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. By replacing the removed plate with a spacer of greater or lesser thickness, the edentulous portion will be raised or lowered respectively precisely by an amount equal to the difference in thickness of the parting plate and its replacement spacer.
