Abstract
This invention is directed to a flared orthodontic buccal tube having an internally tapered mesial section. In a preferred embodiment, the buccal tube includes a base adapted to be secured to a tooth, and a tubular body connected to the base. The tubular body has mesial and distal sections connected at a mesial-distal interface, and mesial and distal bores communicating at a mesial bore-distal bore interface. The mesial section is tapered, with the mesial opening of the mesial bore having cross sectional dimensions exceeding the cross sectional dimensions of the exterior surface of the distal section.
Claims26
A buccal tube, comprising:
- a base adapted to be secured to a tooth;
- and
- a tubular body connected to said base, said tubular body having mesial and distal sections integrally connected at a mesial-distal interface, said mesial and distal sections having mesial and distal ends, respectively, defining the opposite ends of said tubular body, said mesial and distal sections having mesial and distal bores, respectively, communicating at a mesial bore-distal bore interface, said mesial and distal bores having mesial and distal openings, respectively, at their mesial and distal ends, respectively, said distal section having an exterior surface,
- said mesial section being tapered, with said mesial opening of said mesial bore having cross-sectional dimensions exceeding the cross-sectional dimensions of the exterior surface of said distal section, said mesial bore tapering along its length to said mesial bore-distal bore interface.
A buccal tube, comprising:
- a base adapted to be secured to a tooth;
- a body connected to said base and having an element for receiving an orthodontic archwire, said element selected from the group consisting of an archwire slot having a bottom wall and two opposing sidewalls extending therefrom, and a tubular body having a bore;
- and
- an auxiliary tubular body being in substantially side-by-side relationship with said body, said auxiliary tubular body having mesial and distal sections integrally connected at a mesial-distal interface, said mesial and distal sections having mesial and distal ends, respectively, defining the opposite ends of said auxiliary tubular body, said mesial and distal sections having mesial and distal bores, respectively, communicating at a mesial bore-distal bore interface, said mesial and distal bores having mesial and distal openings, respectively, at their mesial and distal ends, respectively, said distal section having an exterior surface,
- said mesial section being tapered, with said mesial opening of said mesial bore having cross-sectional dimensions exceeding the cross-sectional dimensions of the exterior surface of said distal section, said mesial bore tapering along its length to said mesial bore-distal bore interface.
The buccal tube of claim herein said mesial bore tapers along its length at an angle of about 45.degree. relative to the common longitudinal axis of said mesial bore, distal bore and mesial bore-distal bore interface.
