Abstract
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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
230 words
A buccal end tube device for selectively orienting an orthodontic arch wire relative to a tooth, the buccal end tube device being adapted for mounting to a buccal surface of the tooth, the device comprising: at least two arch wire positioning means spaced apart from each other in the axial direction of said buccal end tube, one of said arch wire positioning means defining at least one aperture and the other of said arch wire positioning means defining at least two apertures which are spaced apart from each other in the occlusal-gingival direction, said apertures being adapted to receive spaced portions of the arch wire, said other of said arch wire positioning means comprising a dividing tab member connected to said buccal end tube forming means and extending across said buccal end tube in a direction substantially perpendicular to the occlusal-gingival direction of said tube, said dividing tab member cooperating with said buccal end tube for defining at least two apertures spaced apart from each other in said occlusal-gingival direction, whereby the arch wire may be disposed in a predetermined orientation within an occlusal gingival plane by positioning the arch wire in selected apertures of said at least two spaced apart arch wire positioning means and maintained in the selected orientation against the action of external forces applied both to the arch wire and to the buccal end tube device.
Claim 2
Dependent Claim
