title: Duplication variables related to partial denture castings. 1. The duplicating flask.
abstract: A metal die simulating a model of a partially dentate upper jaw prepared with milled facets for reference measurement with vernier calipers was used for the making of duplicate stone models, in three different duplicating flasks. The observation showed that irrespective of the flask size, the duplicated models were slightly wider.
