Abstract
In preparing dentures, hardened mould material surrounds the denture. This mould material is adhered inside a denture flask with a housing having two separably matable portions. To remove the hardened mould material from the flask, the flask is mounted in a mould press having a shaft, with one of the portions is restrained against movement along an axis of travel of the shaft. A portion of the mould material at an end of the restrained flask portion is available for contact with the shaft along the axis of travel. A capped end of the shaft is forcefully advanced against the adhered mould material therein, thereby breaking the adhesion. After this is done, the denture flask is dismounted from the mould press and the hardened mould material is removed from the first flask portion. If necessary, the process is repeated with the other housing portion.
