コメント

  • This is a pure G6 case using elastics to get a good and comfortable result.
  • During the first series, the patient did not have sensitivity and controlled the wearing time from 9-10 days by feeling (sometimes even 12 days).
  • Class III elastic was added only between stages 34-39 for anchorage control.
  • For the first AA, I just needed to correct the shallow bite, 35 rotation, and bite settling.
  • I tried adding horizontal attachments over posterior teeth for extrusion. But in the end, I also use vertical elastic to reinforce it.
  • Comparing her profile changing, we got a surprising and beautiful outcome.
