コメント

  • Orthodontic camouflage treatment was carried out for this adolescent patient: 14 and 24 were extracted to retract upper anterior teeth in order to correct maxillary protrusion
  • Deep anterior overjet as well as upper and lower dental arch shape discrepancy
  • Class II elastics were used on both sides for mandibular growth stimulation and anchorage control.
  • Different anchorage design for upper extraction sites on both sides to help correct upper dental midline deviation.
  • Lower premolars extrusion combined with lower anterior teeth intrusion to help correct deep anterior overbite as well as level the Curve of Spee.
  • Power ridge design was used for both upper and lower anterior teeth during treatment in order to prevent gingival recession, alveolar bone dehiscence, and fenestration because of soft and hard periodontal tissue hypoplasia.
  • Additional aligners were used according to the patient‘s mandibular growth reactions from Class II elastics
  • Waited with 17, 27, 37 and 47  until erupted enough into dental arches then included in orthodontic treatment with the help of additional aligners
