ABSTRACT:
This invention relates to an orthodontic appliance comprising a low pull and/or a high pull, which low pull preferably extends through and is slidable in a guide sleeve of a nape pad, and the low pull and/or the high pull are provided at each end with a series of holes for a selective connection to spring elements connected to bow means. The novel orthodontic appliance is simpler, less bulky and less conspicuous. This is accomplished in that elastically stretchable flat strips of plastic material are provided at one end with an eyelet for connection to the low pull and/or the high pull at the series of holes and at the other end with an eyelet for connection to the bow means. That arrangement provides a pulling device which is flat rather than bulky and can easily be connected and which is convenient for the patient and can be made to have the color of the skin so that it is less conspicuous.
