코멘트

  • This case was very challenging for me because it had the most severe deep bite I've ever treated
  • This challenge includes a Severe Brachyfacial and Class II skeletal pattern
  • Significantly favorable is that the patient is very young and the retroclination of both upper and lower incisors will virtually improve the deep bite itself
  • My treatment plan was to expand both arches and de-rotating (especially the 1.6) to improve the patients narrow arches
  • Combined with distalization (aesthetic beginning) of the 1st quadrant.
  • Up to 4 teeth moving together to not only create the distalization of the 1st quadrant but increase anchorage and provoke proclination of the lower incisors
  • I used Class II elastics to increase the anchorage 3/16" 4 and 6 Oz - Nigh time wear
  • IPR was performed in order to minimize the necessity of distalization of the 1st quadrant.
  • Expansion of the lower arch (especially of the premolar area) and proclination of the lower incisors to align the anterior teeth and improve the deep bite
  • Note that in the pictures of intermediate stage I show how I did the intercuspation of the posterior sector by cutting of the molar part of the upper and lower aligner, placing buccal buttons in labial of 1st and 2nd molars using 1/8 6 Oz vertical elastics for 2 weeks
