In the orthodontic process, certain torque is required to be generated by using an orthodontic bracket in the orthodontic process, wherein the torque refers to an included angle between a clinical crown long axis of a tooth and a (occlusal) plane vertical line, and the inclination of the labial lingual direction of the tooth is reflected. Different vertical and sagittal bone facial types can compensate the torque, and the torque plays an important role in establishing a good occlusion relationship and achieving the orthodontic treatment targets with stable functions and attractive appearance.
