To optimize the point of force application, the loop should embrace the tooth surface as far as possible. This loop can tip the canine distally as well as lingually.
In order to avoid interference with the occlusion, the labial bow and the transversal tag should not lie too high. If the tooth should be moved distally, there has to be some space between the distal surface of the canine and the transversal tag.
If the loop is bent the other way around, the canine can be moved mesially.
