ABSTRACT:
A strip of stiff paper is wrapped around the edge of a dental cast mounting plate of a dental articulator toserve as a dam for confining moist plaster used for mounting a dental cast to the plate. After the plaster has hardened, the strip may be readily removed, leaving a clean, easily observable edge between the plaster and the plate, which is very helpful in the use of interchangeable plates with dental casts as well as use with the dental "split-cast" mounting plate technique.
