Bemerkungen

  • This was an extraction case with 14/24/38/48 extracted.
  • I design maxillary strong anchorage to retract anterior teeth, and upper molars' mesial movement is controlled less than 2 mm.
  • In mandibular dentition, I design lower molar distalization for about 2mm to retract lower incisors and reduce the inclination of lower incisors.
  • Two mini-screws were used in the maxillary posterior region to enhance maxillary anchorage and help retract lower incisors.
  • Elastic traction is used between maxillary mini-screws and lower canines' precision cuts of lower align.
