Comments

  • The chief complaint of this patient is the midline deviation of both upper and lower arches
  • The patient presented with congenital missing of the 2.2 and peg lateral of the 1.2
  • Therefore the upper midline was shifted to the left side
  • The small-sized 1.2 was extracted to move the upper midline towards the right side
  • The 1.2 and the 2.2 were substituted by the 1.3 and 2.3
  • The lower midline was also shifted to the left side and the missing of the 3.5 was one of the reasons for this
  • Therefore we extracted the 4.5 to move lower midline towards the right side
  • We uprighted 3.4 and 3.6
  • The lower curve of Spee was leveled to raise the bite
