Assists with anchorage control and ensures treatment precision.

The buccal tube is a tubular structure that serves as the "fixation point" for the end of an orthodontic archwire (such as stainless steel or nickel-titanium wire).

Guide wire orientation: The angle and direction of the buccal tube are pre-designed based on the patient's dentition and treatment goals. The guide wire is arranged along a pre-set path, thereby controlling the movement of the molars and providing a stable reference for the alignment and adjustment of other teeth.
