Comments

  • Buccally upright the crown of upper posterior teeth to help correct narrow upper dental arch
  • Spaces gained from upper dental expansion and upper molars distalization combined with pre-treatment upper dental space and leeway space were used to help retract labially proclined upper incisors
  • Class II elasctics were used for mandibular advancement and upper posterior teeth distalization
  • Lower premolars extrusion and incisors intrusion to help correct severe anterior deep overbite
  • IPR was used for upper anterior teeth to help correct Bolton discrepancy in the upper and lower anterior region
  • Upper incisors retraction and mandibular advancement to help correct severe anterior deep overjet
  • Power ridge designs were used for lower anterior teeth to help prevent gingival recession, alveolar bone dehiscence, and fenestration during orthodontic treatment
  • Waited with 15, 25, 45, 17, 27, 37, and 47 until eruption into dentition and all could be included in orthodontic treatment
