评论

  • Invisalign is good for molar distalization and crowding correction.
  • The upper left first molar was distally moved by 1.5mm.
  • Class II elastics were used to enhance maxillary anchorage and help retract upper incisors.
  • Upper and lower midlines were both adjusted.
  • The aligner treatment was finished in 11 months with good result.
  • 27 was intruded for 3mm and a fixed bonded retainer was use to maintain the vertical position of 27 before 37 restoration.
