The present invention provides an orthodontic process phased into two or more sub-processes for repositioning a patients teeth. In each sub-process, a complete treatment plan is established, but not all (i.e. only some) appliances in the plan are fabricated to move the teeth, out of the expectation that teeth movement may not completely follow the full course as planned. The entire orthodontic process is thus featured with dynamic planning and incremental implementation of the plans, to address ever-changing treatment profile.
