  • Rotations and tipping of 1.3 (UR3) and 2.3 (UL3) corrected

Comments

  • Besides the correction of any residual crowding and for finishing of the rotation and root tipping, the reason for refinement is to reduce the proclination of the upper incisors
  • Occlusal clearance for maxillary retraction is done by both intrusion of the lower anterior teeth and IPR between them
  • Refinement was made with new photos and new impressions
