  • Treatment planning was leveling curve of Spee, intruding lower incisors and extruding premolars.
  • Also a great smile arc was achieved, by giving a curve over upper incisors and 4mm expansion on the upper arch and a verticalization of lower molars and premolars.
  • Buccal corridors were almost eliminated. All spaces were closed and oclussion was improved.
  • A good interdigitation was achieved.
  • Midlines were corrected, and the heights of the upper incisors were leveled.
  • A little distalization of the upper arch was planned to get a better CI molar and canine relation.
