Abstract
A disclosed orthodontic metal square arch wire (1) consistent with a dental arch curve is applied to a stage of retracting anterior teeth and closing tooth extraction clearance when a straight-wire arch sliding method is used. The arch wire (1) has a rectangular cross section and is divided into a front segment and a rear segment. The front-segment arch wire (2) (an area between two lateral incisors) has the lingual root torque with an angle of alpha, and enters a groove and tightly clamps a groove (4); the front-segment arch wire and the groove have no relative displacement at the sagittal plane; and the edge crossing angles of the arch wire are 90 DEG. The rear-segment arch wire (3) has the obtuse edge crossing angles at the cross section, is flat and straight, has no torque and is consistent with a buccal tube and a bracket groove. By adding the torque to the front-segment arch wire, lip root inclination (lingual crown inclination) is avoided to the greatest extent during retraction of anterior teeth, and the uttermost integral parallel movement of anterior teeth during the whole retraction is guaranteed. Due to the fact that the rear-segment arch wire has no torque and a certain clearance is kept between the arch-wire rear segment and the buccal tube and the bracket groove, the frictional force between the arch wire and the groove is reduced when the tooth extraction clearance is closed and the arch wire moves backward.
