Bemerkungen

This was a difficult case:

  • Male teenager with growth potential, skeletal class III with only a small amount of functional shift.
  • Besides leveling and relief crowding, I planned a horizontal and anteroposterior jump in clincheck,
  • That was achieved by excellent prediction of mandible displacement (functional shift) and excellent simulation in clincheck.
  • By using U6 to L4 Class III elastic, we achieved an excellent treatment result.
  • In anterior crossbite cases, Invisalign acts as an excellent bite raiser, and with the help of patient's compliance, we can easily achieve
    good outcomes.
