ABSTRACT:
A bite correcting appliance for correcting an overbite or underbite condition of a patient includes upper attachment structure, lower attachment structure and a stretchable, close coil spring connected between the upper and lower attachment structures. The close coil spring exerts a pushing force on the lower jaw as the patient's mouth closes and is substantially non-prestressed or non-preloaded. At least one end of the appliance includes a deformable or crimpable portion allowing selective locking and unlocking to the corresponding attachment structure. Upper and lower attachment members are connected with the close coil spring by both threading and crimping to the spring.
