What is thermoforming?
The thermoforming process involves preheating a sheet, which becomes pliable and can be

- Firstly, the type of device is crucial - whether a vacuum chamber or a pressure chamber is used on the heated foil. This directly impacts the accuracy of the fit to the model.
- Vacuum forming: A constant vacuum pressure is applied to the foil using a vacuum pump (vacuum pressure value of 0.7 bar).
- Pressure forming: Overpressure is created by a compressor (pressure value of 3–6 bars).
- Secondly, it is essential that the sheet is heated consistently during each process to ensure the process is repeatable.
- Finally, the type of foil used is important – there is a wide range of materials and thicknesses that must be appropriately selected for the type of work.
Thermoforming is particularly valued for its detailed reproduction of features, which is crucial in aesthetic and precise work. This technique is widely available in modern dentistry, becoming an indispensable method for performing both orthodontic and prosthetic tasks.
