About flasks and hydraulic presses
A denture flask is a metal or fibreglass vessel that supports the gypsum mould in which a denture is polymerised. Packing is the pressing of denture base material into the mould inside the flask. Compression moulding is a common way of curing acrylic resin.
Denture processing is the means by which denture base material is polymerised into the form of a denture. Firing is the process of porcelain fusion, used in dentistry to produce porcelain restorations.
The FDA describes dental porcelain as a powder heated to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.
How presses, curing units, furnaces and formers differ
- Flask & Hydraulic Presses — Holds the mould and presses the resin into it.
- Denture Curing Units — Polymerises the resin once it is in the mould.
- Furnace Units — Heats ceramics to firing temperature; wax elimination, the removal of wax from a mould, is also usually done by heat.
- Furnace Parts — The replaceable parts of a furnace, such as the muffle.
- Curing Lights & Parts — Polymerises resin with light of a set wavelength range.
- Vacuum Formers & Injectors — Shapes a softened sheet over a cast, or injects material into a closed mould, in place of packing a flask.
What to look at when choosing
Processing method: an injection method was developed to deal with the shrinkage of heat-cured acrylic in compression moulding.
Temperature: ISO 13078 exists because a furnace has to be calibrated; its method covers 600 to 1,050 degrees Celsius.
Cleaning between cases: the CDC notes that pressure pots and water baths are particularly susceptible to contamination and should be cleaned and disinfected between patients.
