Buccal end tube for holding orthodontic arch wire - has two wire positioning points with wire receiving apertures to permit appropriate alignment of wire

摘要

The buccal end tube device includes at least two spaced apart arch wire positioning points. One of the arch wire positioning points has at least one aperture and the other has at least two apertures (11,12) which are spaced from each other in the buccal-lingual or occlusal-gingival direction. The arch wire (16) may be disposed in predetermined orientations within a buccal-lingual or occlusal-gingival plane by positioning the arch wire in selected apertures defined by the two spaced apart arch wire positioning points. The arch wire is maintained in the selected orientation against the action of external forces applied to both the arch wire and to the buccal end tube device.
