How accurate is the HeadSTEP thermoplastic based system? Do the accuracy values differ between Maxi and Micro masks?
The HeadSTEP shows under normal circumstances an accuracy of 1 to 5mm. Publications document the high accuracy of our product. The difference between Maxi and Micro thermoplastic masks is about 2mm. What is the right hardening time for the mask? After taking the mask out of the water bath it has a temperature of about 37°C, nearly bodytemperature. The mask cools out and stiffens after moulding and so becomes a rigid replication of the patient’s anatomy. The mask has to remain on the patient’s face for a minimum of 5 minutes, below this time shrinkage is possible.
