The understanding and management of torques in orthodontic treatment allows the orthodontist to control mechanics without making mistakes that can jeopardize the longevity of the teeth.
An example of these possible errors is the situation portrayed in the video, in which the upper anterior teeth present an excessive buccal inclination. The insertion of a rectangular wire with REAL NEUTRAL TORQUE incorporates a crown NEGATIVE RELATIVE TORQUE (root positive) due to the difference in inclination between the bracket slot and the rectangular wire cross section, with the center of rotation of the movement located in the center of resistance .

During the retraction of the anterior teeth, on the other hand, it is possible to change the inclination of these incisors in a controlled way, placing the center of rotation close to the apex of these teeth.
Bracket prescriptions cover the average of cases, not extreme situations!
