ABSTRACT:
A frame is provided for firmly securing a dental press holding one or more flasks during preparation of dental prostheses. The frame securely locks the press in position and facilitates tightening of the press to exert pressure on the dental flasks as well as release of the pressure once the procedure is completed. Use of the frame permits a single technician to tighten and loosen the press with a single hand and allows greater tightening of the press to exclude voids and pockets in the finished prosthesis.
