摘要:
A method and apparatus for correcting Class II and Class III malocclusions is disclosed. More specifically, the described orthodontic bite corrector may be installed on multiple points of attachment, including an archwire or an orthodontic band. Preferably, the bite corrector is comprised of a coil spring wrapped around a push rod, the coil spring and a portion of the push rod being contained within a spring housing. A mechanism of attachment is also provided on both the rod and the housing. The mechanism of action is such that the majority of corrective forces are the result of spring expansion, rather than spring compression.
