评论

  • Sequential distalization with the use of Class II elastics
  • The sagittal jump accounted for 20% of the sagittal correction
  • During the orthodontic treatment, the maxillary and mandibular dental arches were aligned and maxillary and mandibular incisor inclinations were improved
  • Ideal overjet was obtained at the end of treatment.
  • The ideal overbite was obtained mainly by intruding the mandibular anterior teeth
  • For the correction of the deep bite, we first leveled the Curve of Spee and further along in the treatment lower IPR was performed
  • The left maxillary lateral was extruded to match the homologous tooth at the gingival level
  • Some grinding was performed at the incisal edge at the end of treatment
