Comments

  • The patient is missing the 3.1 and 4.1
  • I extracted the 1.4 and 2.4 and used the maximum anchorage of the posterior teeth to close the space
  • Class Ⅱ elastics have been used to strengthen the anchorage of the upper teeth
  • I found at the end of the treatment that the upper posterior teeth still had a little mesialization
  • Distalized the upper teeth one by one during the refinement
  • The result was very good
  • We managed to obtain the class Ⅰ relationship
  • We closed the space on the lower teeth
  • Use of IPR to get the Bolton ratio coordination
  • TADs were used to improve the gummy smile
  • At the end of the treatment, we saw a great improvement in both the patient's profile and smile

Retention

  • Maxillary: Vivera
  • Mandibular: Vivera
