Comments

  • Sequential distalization was done, associated with the use of Class II elastics at night time.
  • The sagittal jump accounted for 20% of the sagittal correction.
  • During the orthodontic treatment, the maxillary and mandibular dental arches were aligned, and maxillary and mandibular incisor inclinations were improved.
  • Posterior crossbite correction was performed with the auxiliary use of 1/4 crossbite elastics for the first 30 stages of treatment, running from teeth 2.4 and 2.5 palatally to tooth 3.6 buccally at night time.
  • Expansion was performed in both arches.
  • Ideal overbite was mainly obtained by intruding the mandibular anterior teeth.
  • Correction of the deep bite, leveling of the Curve of Spee was done initially, and only later lower IPR was performed.
  • Ideal overjet was obtained at the end of treatment
  • Gingival health was maintained at the end of orthodontic treatment.
