Comentarios

  • This is a high-efficiency extraction case that was finished in 18 months.
  • The patient was away for work so the treatment was stopped for 10 months between the second and third MCC.
  • All aligners were used just for a week.
  • G6 system worked very well to achieve moderate anchorage and aligned the displaced upper canines in 36 weeks.
  • IPR was a necessary way to level the curve of Spee if a non-extraction plan was chosen in the lower arch.
