Results achieved

  • Class I relationship achieved
  • Normal  overjet and overbite achieved
  • Midlines coincident
  • Proper axial inclination of incisors
  • Arches aligned and coordinated
  • All treatment goals were achieved case

Comments

  • The treatment was designed to control the upper and lower arches in three dimensions. Both arches were expanded and coordinated.
  • Distalization and intrusion of upper molars and retraction of upper anterior teeth corrected Class II molar relationship and open bite simultaneously.
  • All treatment goals were achieved as designed in the ClinCheck plan.
  • The actual numbers of upper aligners were 22+10+36 with 2 additional aligner orders. The reason was that the patient’s mandible position was unstable and always went forward, so the ClinCheck plan was modified to reduce the pre-mature contact of the anterior teeth.
  • The actual numbers of lower aligners were 15+10+6. More IPR was done to decrease the proclination of the lower incisors.
