评论

  • First refinement done to further expand maxillary arch and extrudeall incisors
  • Second refinement was done by striping 0.2 mm in the mandibular arch at the incisors and canines. Class III elastics were used to get further retraction of the lower arch and thus improve the overjet.
  • This treatment teaches us that the use of a systematic alignment and intrusion of the maxillary dentition in a later phase helps us improve the closure of an anterior open bite.
