Bemerkungen

  • Expansion in the upper arch as needed to obtain space for 1.2 and increase intercanine width in combination with the use of MA Precion wings to allow class II correction
  • In the lower arch the crowding was corrected through expansion and proclination
  • Additional aligners were used to extrude 1.2 once space was created
  • The patient ended his phase 1 of treatment with Class II corrected into an almost a Class I molar relationship considering that lee way space will be used since still in mixed dentition
  • The case will be evaluated in the next 1-2 years and if needed a short phase II to correct minor tooth movements of permanent canines and bicuspids will be done
  • I shared this case to show how important the use of a phase I treatment for a growing patient with the use of not only tooth movement but also a functional treatment can be
