ABSTRACT:
A buccal end tube with a pair of spaced apart arch wire positioning means, one positioning means defining at least one aperture and the other positioning means defining at least two apertures which are spaced apart in the buccal-lingual or occlusal-gingival direction, said apertures being adapted to receive spaced portions of an arch wire. The arch wire may be disposed in a predetermined orientation within a buccal-lingual or occlusal-gingival plane by positioning the arch wire in selected apertures of the spaced apart arch wire positioning means and is maintained in the selected orientation against the action of external forces applied both to the arch wire and to the buccal end tube device. The means defining the apertures preferably comprises a tab or divider means extending from and integral with a portion of the buccal end tube. A buccal end tube also comprises at least two hook members which are spaced apart in the longitudinal direction of the buccal end tube, the projecting portions of the hook members being directed toward each other. The hook members are preferably symmetrically located on the buccal end tube device.
