1. A method of straightening teeth comprising:

  • forming a thin sheet-like plastic overlay of the teeth, including the tooth to be straightened and at least some of the teeth on either side of said tooth, said overlay being of a thickness so as not to violate the freeway space between upper and lower occluding teeth surfaces;

    providing a spring like tensioning member having the ability to undergo deformation while retaining its spring memory;

    providing a resilient tubular member for at least partially encasing said tensioning member;

    placing said tensioning member inside of said tubular member, a portion of the tensioning member being positioned for engagement with said tooth to be straightened;

    securing said tubular member and said tensioning member to the surface of said overlay in a manner to cause one or more bends in both the tubular member and the tensioning member; and

    placing said overlay inside of the mouth of a wearer with said portion of said tensioning member engaging said tooth to be straightened,whereby said tensioning member effects movement of said tooth to be straightened while said overlay provides an anchor for holding the remaining teeth stationary.
