评论

  • Use of moderate anchorage design for the extraction sites to address maxillary and mandibular protrusion
  • Mild crowding, as well as upper and lower denture protrusion
  • Use of Class II intermaxillary elastics to help control anchorage;
  • Use IPR to help correct Bolton discrepancy
  • Control the lingual movements for the roots of upper and lower anterior teeth during retraction to help prevent gingival recession
