Dimensional accuracy of duplicate dentures prepared by different methods.
The production of a duplicate denture demands a high degree of perfection to maintain dimensional accuracy of the duplicate denture. Duplicate dentures were made by four methods in order to investigate the dimensional accuracy in relation to a master denture. Replicas made from modeling wax (all-wax replica or acrylic resin base-wax teeth replica) demonstrated better dimensional accuracy compared with the all-acrylic resin replicas. It is well known that modeling wax used alone as a temporary denture base is an unsatisfactory material. The inherent shortcomings of the material may be overcome if dentists and patients make their assessment of the duplicate as quickly as possible in the mouth. The other alternative may be the production of a duplicate denture with an acrylic resin base and modeling wax teeth.
