Comments

  • Good patient compliance
  • Overcorrection for posterior on heavy occlusal contacts
  • IPR of 0,5mm on 1.1 and 2.1 was not necessary
  • We created enough overjet for closing space on the 1.1 and 2.1 by performing IPR on the lower anterior teeth during the 1st stage
  • We intruded the lower anterior teeth to level the lower arch curve of Spee
  •  For aesthetic concern, gingivectomy at the upper 3's was performed for longer clinical crown
  • Upper labial frenectomy was performed to achieve a better smile pattern and avoid relapse of diastema

Retention
