Abstract
The invention relates to a dental mold flask (10) for production, in particular for injection molding, of dental molded parts, with at least two mold shells (12) via which a mold cavity (14) can be formed for introduction of polymerizable plastic through a filling channel (16), and with an air release channel (42) for the air that escapes during filling of the mold cavity (14). The air release channel (42) has a filter element (40) whose permeability for air changes automatically, in particular decreases, as soon as it comes into contact with the polymerizable plastic.
