| 摘要 |
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. |
