Narrow arches. Crowding. And a patient who didn’t want braces.
The challenge was to develop the arches and resolve the crowding without relying on anterior flaring.
Case highlights:
🔹Diagnosis: Class I, constricted aligner case
🔹Primary concerns: Maxillary arch constriction, crowding & overbite
🔹Key challenge: Develop the arches while maintaining appropriate tooth position
🔹Treatment approach: Clear aligners with a structured 3-phase protocol
🔹Treatment time: ~14 months
🔹Outcome: Improved arch form, alignment, occlusion & smile esthetics
The interesting part of this case is how the movements were sequenced.
Transverse development came first, with careful attention to vertical control and lower arch uprighting. From there, the focus shifted toward settling the occlusion and finally addressing the smaller finishing details.
It’s a great example of why successful aligner treatment starts with clear objectives, not just a digital setup.
We walk through the entire case, including the treatment planning, biomechanics, attachment strategy, and progression through each phase in the full case study.
