コメント

  • Because this was a teenager case with short dental crown, we used modified G6 attachment system to close the extraction space and the result was great.
  • 5mm over-jet and 5mm over-bite were fully corrected.
  • One week change of aligner was available for cooperative teenager.
  • Class II elastics was necessary as the anchorage of upper molar was weaker than the anchorage of lower.
