About denture flasks
The flasks on this shelf are made for compression, injection and pour techniques, for microwave curing and for duplicating.
A denture flask is a metal or fiberglass vessel that supports the gypsum mold in which a denture is polymerized. Denture processing converts the wax pattern of a denture into resin. Packing is the filling and pressing of the denture base material into the mold inside the flask.
For injection molding the waxed denture is flasked and boiled out as for compression molding, and a hollow sprue is attached to the mold cavity.
How flasks and flask accessories differ
- Denture Flasks — The vessel that holds the mold.
- Flask Accessories — The tools and supplies used around the flask, not the flask itself.
What to look at when choosing
Technique: the flask follows the resin. Pour-type resin is poured into molds of agar hydrocolloid or modified plaster. Microwave curing is done in a special fiber-reinforced flask.
Injection: in injection molding, resin keeps entering the flask while polymerization shrinkage occurs.
Distortion: warpage of the base when the cured denture is removed from the cast is considered a major disadvantage of acrylic resin, and it can change the position of the teeth. A classic study gave the flow of the resin into all regions of the mold as a reason for letting the closed flask stand for at least an hour.
