The present invention provides a device and procedure for straightening and leveling of teeth anterior to the molar (chewing) teeth. The procedure utilizes a blocked tube having a channel and an extension and blocking wall. The extension extends from the blocked tube and is substantially parallel to the channel, and the blocking wall extends upward from an end of the extension and is substantially perpendicular to the extension. The blocking wall extends to a same height as the channel with respect to a bottom of the blocked tube. The procedure further uses conventional brackets and wires. The wires are ligated to the brackets and threaded through the channel of the blocked tubes. The wires are cut and contact the blocking wall of the blocked tube. |
