ABSTRACT:
An adjustable band for orthodontic use which is formed of a strip of relatively soft material, such as annealed metal or flexible plastic, is provided. In one embodiment, one end of the band contains tabs which are formed into a shackle and flexible projections. The other end of the band comprises a tang which contains rectangular indentations into which the projections fit. In another embodiment of the invention, the band is formed in a one-piece construction of molded plastic. The band of the second embodiment comprises a strip having a tang portion on one end and a shackle portion on its opposite end, where the shackle incorporates a slot through which the tang can be inserted. In both embodiments, when the tang is placed into the shackle, a cylindrical loop is formed which can be placed over a tooth and drawn into approximately the diameter of the tooth. Further tightening creates forces which shape the band around the tooth to match the contour of the tooth.
