11. An orthodontic system comprising:
a removable segmentary left shell for being fitted on a left segment of teeth in a posterior left lateral sector of a maxillary arch in a starting position of the left segment of teeth in a first treatment, the left segment of teeth comprising adjacent teeth and extending from a left canine left molar and including left premolars;
a removable segmentary right shell for being fitted on a right segment of teeth in a posterior right lateral sector of the maxillary arch in a starting position of the right segment of teeth in the first treatment, the right segment of teeth comprising adjacent teeth and extending from a right canine to a right molar and includes right premolars;
a right anchor configured to be fitted on a tooth on a right side of a mandible;
a left anchor configured to be fitted on a tooth on a left side of the mandible;
a plurality of resilient traction elements; and
a plurality of complete shells, wherein the complete shells are shaped to be fitted on the teeth of the maxillary arch in consecutive positions of a second treatment; wherein
the left and right removable segmentary shells each comprise a labial retention feature configured to be coupled with the resilient traction elements and wherein the removable left segmentary shell and the removable right segmentary shell are not connected to each other; and wherein
the removable right segmentary shell is configured to apply only distal forces to the right canine and right premolars and rotational forces to the right molar responsive to extension of one of the resilient traction elements between the right anchor and the labial retention feature on the removable right segmentary shell, without transferring the forces to other teeth outside the right segment in the maxillary arch; and wherein
the left segmentary shell is configured to apply only distal forces to the left canine and left premolars and rotational forces to the left molar responsive to extension of one of the resilient traction elements between the left anchor and the labial retention feature on the removable left segmentary shell, without transferring the forces to other teeth outside the left segment in the maxillary arch, and wherein
the first treatment is a treatment for treating a class II malocclusion to arrive at a class I malocclusion, and wherein the second treatment is a treatment for resolving the class I malocclusion.
