Ceramic flask technique for duplicating a complete denture.
The possibilities for use of the duplicate denture are many. The duplicate denture serves as an excellent custom tray for the final working impression. If it is acceptable on the existing denture, the vertical dimension of the duplicate denture can be directly transferred to the articulator. If not acceptable, the vertical dimension can be altered and checked intraorally by adding or removing acrylic resin on the occlusal surface of the teeth. Alterations in esthetics, phonetics, and occlusion can easily be achieved and tested by replacing the original teeth of the duplicate denture with stock acrylic resin teeth. Alterations to the duplicate denture with subsequent patient approval prior to construction of a new prosthesis eliminates many problems associated with new dentures.
