Abstract
Abstract Two spaced substantially parallel tabs are supported on a mounting portion which may be in the form of a welding flange connectable to a tooth band. According to the presently preferred embodiment, each of the tabs is provided with a plurality of apertures. At least the wire receiving ends of the apertures are tapered to facilitate location and entry of the arch wire into the respective apertures. By selectively passing the arch wire through preselected apertures, the wire can either be passively positioned in the buccal end tube device wherein it does not exert any forces on the tooth or, alternately, it can engage the device actively wherein rotating as well as tipping forces can be applied to the tooth on which the end tube device is mounted. An end tube device is also described wherein a buccal tube is mounted adjacently to the end tube device and is provided with a slot through which an arch wire can pass interiorly of the tube. When so used, the buccal tube replaces one of the apertured tabs and offers greater versitility for applying forces to the tooth than provided by the two apertured tabs.

Claim 13
Dependent Claim
58 words
A buccal end tube device as defined in claim 1, wherein each of said apertures has an end portion normally first approached by an arch wire successively passing through said respective apertures, each of said apertures being provided with tapered portions at said end portions, whereby location and entry of the arch wire into said apertures is facilitated.
Claim 14
Dependent Claim
56 words
A buccal end tube device as defined in claim 1, wherein said apertures are provided at each end thereof with tapered portions, whereby location and entry of the arch wire into one of the apertures of each of said tabs is facilitated irrespective of the order of successive entry of the arch wire into said tabs.
