Comments

  • This is a typical skeletal Class II malocclusion treated by orthodontic camouflage, aiming at full Class II molars by extracting upper first premolars.
  •  Two upper first premolars were extracted to gain space for upper anterior teeth retraction.
  • IPR was used on lower anterior teeth to level the arch.
  • Two TADs were used to help intrusion and torque control of upper anterior teeth.
  • Clincheck is very useful in treatment planning for orthodontic camouflage and the result is predictable with smart track aligners.
  • Since the patient was very satisfied with the treatment outcome and the midline shift was not her concern, I did not ask for more additional aligners.
