ABSTRACT:
Upper and lower plaster study models are cast in sequence from impressions held in trays positioned over the same base former having a molding cavity dimensioned close to the final trimmed shape of the base portions of the study models. Tray alignments procedures utilized during the casting operations guide positioning of the trays to enable formation of study models that require minimal trimming.
