评论

  • Class I relationship was achieved by distalization of upper posterior teeth and IPR in conjunction with class II elastics.

  • Overjet was significantly reduced by retraction of upper & lower incisors in conjunction with IPR.
  • Esthetic contouring was performed in the incisal edges of upper incisors after treatment.
