ABSTRACT:
A safety orthodontic neck band including a resilient band connected at its ends with an extra-oral orthodontic appliance for tensioning purposes when the orthodontic appliance is applied to the teeth of a patient. The apparatus also includes a non-extensible safety band which is co-extensive with the resilient neck band and overlies the resilient neck band in close proximity. The safety band also connects to the ends of the orthodontic appliance to thereby prevent accidental or unwanted movement of the extra-oral orthodontic appliance forwardly relative to the teeth of the patient. The orthodontic neck band including safety strap of the present invention functions to prevent forward movement of the orthodontic appliance and at the same time continuously tensions the appliance during all periods of use.
