评论

  • Distalization was planned for the upper left arch and a combination of distalization and mesialization for the upper right arch
  • Class II elastics (6 1/2 oz 4.8mm heavy) were advised for night use only
  • At the end of the initial aligners, the closure of all extraction spaces was achieved
  • For midline correction the patient used class 2 elastics on the left side and class 3 elastics on the right side during the 2nd additional aligners phase
  • The patient's cooperation was so good that he used elastics for 24/7 instead of only during the night
  • This great patient cooperation made it possible to achieve midline and anterior-posterior corrections at aligner 16 rather than aligner 20
  • At the final refinement, IPR on lower anterior and extrusion of the upper anterior were planned for a better overbite and overjet relationship
