The problem in this case was that this patient already had upper premolar extractions during previous teen age orthodontics, yet he presents with retroclined upper incisors and severe crowding of his lower labial segment – LL2 was blocked out buccally and aligning the lower teeth within the alveolar bone on a non extraction basis would compromise periodontal health.
Therefore lower arch treatment would require extraction. If we aligned the upper teeth, the central incisors would procline and increase arch length. If we extract in the lower we could reduce arch length.
The question posed was what would the resulting overjet look like after treatment, would it be acceptable? I hope you agree that the finished result correlates closely with the Archwise predicted outcomes.
This case demonstrates the advantage of digital planning with Archwize to produce predicted outcomes.
