Table 3 Torque exerted on the tooth for brackets at different vertical distances from the cusp tip

From: The effect of vertical bracket positioning on torque and the resultant stress in the periodontal ligament—a finite element study

Distance (mm)	Torque (Nmm)^a	∆ Torque
1.5	−30.186
2	−28.557	1.629
2.5	−27.11	1.447
3	−26.312	0.798
3.5	−22.879	3.433
4	−19.887	2.992
4.5	−8.559	11.328
5	4.588	3.971
5.5	29.306	−24.718
6	42.937	−28.631

^aPositive values demonstrate lingual crown torque. ∆ Torque, difference of torque between two subsequent bracket positions.
