  • Gender: female
  • Invisalign Treatment Option: Full

Total Treatment Time

Number of aligners

  • Maxillary: 42 + 33 + 20 = 95
  • Mandibulary: 46 + 33 + 20 = 99

Results achieved

  • Class I relationship achieved
  • Class I relationship maintained
  • Functional canine guidance on both sides
  • Anterior crossbite corrected
  • Posterior crossbite corrected
  • Normal overjet and overbite achieved
  • Deepbite improved
  • Overjet improved
  • Significant improvement ofoverbite
  • Significant improvement of overjet
  • Midlines coincident
  • Proper axial inclination of incisors
  • Curve of Spee levelled
  • Arches aligned and coordinated
  • Alignment of both arches through derotation
  • Arch form improved
  • Aesthetic smile linewas achieved
  • All treatment goals were achieved case
  • Harmonic arches were achieved

Comments

  • Upper arch posterior bilateral expansion in order to correct the lateral cross-bite on the right side.
  • Upper Incisor proclination.
  • Conventional lingual bite ramps at lingual of UR1 and UL2 helped to intrude upper central incisors.
  • Aesthetic Start of lower anterior from L1 to L7. The patient achieves partial lower anterior alignment so becomes motivated and the compliance in wearing full time 22 hours aligners+class III elastics is guaranteed.
  • Lower Second Molar distalisation measurements : 3.4 mm distalisation of LR7 and 3.2 mm distalisation of LL7.
  • Sequential lower arch distalisation : " When the lower second molar has been distalized 50% of the total distalisation distance then the first Lower molars start to distalize ( this sequence is applied for lower second premolars, first premolars, canines and lower incisors )
  • Full time 22 hours Class III elastics + Aligner wear during total treatment time.
  • Intrusion of teeth UR1, UL1 was done in order to level upper incisor gingival margins and also to leave space for composite reconstruction of teeth UR1, UL1
  • Post Invisalign bleaching and composite reconstruction of incisal edges of teeth UR1, UL1 was done by our prosthodontist.
