Torque control and maxillary incisor retraction: what is the problem?

Renato Parsekian Matins

INTRODUCTION: Incisors retraction demands control over the torque of these teeth. The mechanics used needs to be different depending on how the orthodontist wishes their positioning at the end of the treatment. OBJECTIVE: This article aims to explain, in a simplified manner, what is necessary for the orthodontist to control the torque of maxillary incisors during retraction. The relationship between the applied retraction force and the binaries to control the lingualization effect will be discussed and illustrated. CONCLUSION: When the orthodontist plans to retract the incisors, either to close spaces or to distalize the entire arch, it is necessary to plan their final axial positioning and plan how the mechanics will be performed. It should not be forgotten that in order to have control of the incisors, there must be binaries within the orthodontic wire-bracket slot interface.
