Comments

  • The patient’s anterior teeth are lingual, tooth 12/22 were microdontia and the torsion angle was almost 45°.
  • After treatment Phase 1,11/12 had still deep overbite, and the rotation of 12 was not corrected. There were some spaces in the lower dentition.

So we suggested:

  • The overtreatment is necessary for the deep overbite I°patient.
  • If the rotation of microdontia is too large and the attachments are placed on teeth, the correction angle may not be completed.
  • Therefore, we can use the auxiliary traction device to help rotation control.
