Bemerkungen

  • The main concern was protruded teeth. The patient could not close her mouth at night.
  • This was a premolar extraction case, but the patient refused to extract her premolars. I had to distalizate the molars from 3.1 to 5.0 mm with the help of micro implant anchorages in four quadrants by extracting 4 wisdom teeth.
  • The buccal gum of tooth 1.4 atrophied at the 29th of the initial aligners, so I asked for additional aligners to correct the movement of premolars. Then buccal gum of tooth 1.4 came back.
  • The aligners moved both the crowns and roots and made the roots parallel.
