Patent ID: 8177552

Claim:
In a method of intraorally treating a patient wherein an elastomeric continuous orthodontic band is looped around an anchor point on the upper jaw and around an anchor point on the lower jaw to cause relative movement of an upper tooth and a lower tooth, the improvement being in (a) providing a plurality of sets of bands each of which has the characteristics of (1) an outer perimeter simulating the profile of an object with an open area within the perimeter and (2) being made of a resilient elastic material capable of being stretched and capable of tending to return toward its unstretched shape and (3) the outer perimeter in its unstretched condition being of a shape which is non-circular and non-elliptical and which is not a smooth continuous endless curve to thereby simulate the profile of the object; the sets of bands differing from each other in size and shape with each shape corresponding to a specific size, (b) selecting the desired size band from the sets based on the shape of the band, (c) stretching the band, (d) mounting the band on an anchor point on the upper jaw and an anchor point on the lower jaw by looping the open area within the perimeter around the upper jaw anchor point and around the lower jaw anchor point, and (e) forming the open area within the perimeter into a continuous smooth endless curve when the band is mounted to the anchor points in the stretched condition of the band.
