About vacuum formers and injectors
Vacuum thermomolding heats a plastic sheet until it softens and then adapts it to a cast by vacuum, air or mechanical pressure. A vacuum forming machine draws the heated sheet onto the model by suction; a pressure forming machine presses it on.
Waxing is the contouring of a wax pattern, or of the wax base of a trial denture, into the desired form. A wax pattern is a wax form that is the positive likeness of the object to be made.
The FDA lists dental wax for constructing the patterns from which metal crowns and bridges are cast as a Class I device (21 CFR 872.6890). Vacuum thermomolding heats a plastic sheet until it softens and then adapts it to a cast by vacuum, air or mechanical pressure.
How the heat sources and formers differ
- Vacuum Formers & Injectors — Forms a heated plastic sheet over a model; it does not work wax.
- Wax Pots Melters & Heaters — Melts wax with electric heat, without a flame.
- Wax Carving Pens & Tips — The heated tip that carries and shapes the wax, where a pot only melts it.
- Burners & Alcohol Lamps — An open flame at the bench, in place of electric heat.
- Torches & Torch Fuel — A hotter, directed flame for soldering metal, not for wax.
What to look at when choosing
Heat source: a flame or electric heat. In one study the electric source gave less linear shrinkage of the wax pattern.
Timing: the same study found that patterns went on shrinking between one hour and 24 hours and concluded that a wax pattern should be invested immediately.
Forming method: a pressure forming machine gives a steadier forming pressure and may suit materials that need more pressure or more precise shape.
