the SNA and SNB a retruded maxilla and mandible. A popular computer diagnostic service recommended extraction of maxillary 1st bicuspids and mandibular 2nd bicuspids (Fig. 4). We will proceed with CAD. TREATMENT OBJECTIVES The essential treatment objectives were to upright and distalize all posterior segments simul-taneously (i.e. coordinate upper arch tooth move-ments). Create space for the blocked cuspids and reeducate the soft tissue envelope to accept the new transverse dimension of both arches. The case will be finished so occlusal forces of function are directed through the long axis of the teeth ( your best long term retainer). From the following two cases we see, as we discussed earlier, that the Coordinated Arch Devel-opment is a combined orthopedic/orthodontic approach to long term stability, applied during peri-ods of optimum growth and development. I invite everyone to read “Non EX Factors: Using The Coordinated Arch Development” to further review the treatment flowcharts and treatment x-rays associated with the previous two cases.
