评论

  • Used molar distalization and post arch expansion to correct arch form and retract flared upper incisors.
  • Class II elastics helped as well to reduce overjet.
  • Besides, good control of incisor intrusion and premolar extrusion is very important to deep bite correction.
  • Class I canine and molar relationship was well achieved.
