1. A method of immobilizing the head of a patient, the method comprising the steps of:
heating a thermoplastic mask preform to a formable temperature;
forming the thermoplastic mask preform over at least a mouth of the patient;
pushing a mouth receiving end of a bite piece into a portion of the thermoplastic mask preform that is positioned over the mouth of the patient, thereby moving the portion of the thermoplastic mask preform into the mouth of the patient; and
allowing the thermoplastic mask preform to cool from the formable temperature, thereby causing the portion of the thermoplastic mask preform to harden.
