LONG-TERM CONTROL OF THE STABILITY OF SKELETAL STRUCTURES IN CLASS-II DENTOSKELETAL DEFORMITIES AFTER SURGICAL-ORTHODONTIC THERAPY

This study analyzes long-term findings in a group of 10 patients with Class II dentoskeletal malrelationship and who have undergone orthognathic surgical procedures. Changes in cephalometric values relative to the bony structures of the upper jaw and of the mandible are discussed in detail. Patients were reexamined on average, 5.8 years after surgery to show possible modification of the skeletal regions in patients who underwent surgical-orthodontic treatment for malformation of the facial continuum. For each case we made a cephalometric analysis of the lateral cephalograms, as well as the superimposition of tracings relative to the various stages of treatment: at the end of preoperative orthodontic treatment, after surgery, and at the long-term control. Cephalometric values for all patients who took part in this long-term control were recorded and a structural assessment was made.
