Patient Demographics & Malocclusion

• Age: 15 years old

• Primary Concerns: Deep bite, arch crowding, tooth rotations

Pre Treatment images:

Treatment Strategy & Biomechanics

• Space Creation: No IPR (Interproximal Reduction) performed

• Arch Mechanics: Roundtripping strategy utilized—initial controlled expansion/proclination to gain space and unravel rotations, followed by arch consolidation

• Vertical Management: Deep bite leveling integrated throughout active staging

Mid Treatment follow up

Aligner Protocol & Sequence

• Wear Schedule: 7 days per aligner (1 week/step)

• Initial Phase: 23 aligners (approx. 5.5 months)

• Refinement Phase: 5 aligners (approx. 1.2 months)

• Total Tray Count: 28 active aligners

• Total Active Duration: ~7 months (assuming 20–22 hours daily wear compliance)

Post Treatment

Clinical Summary The case resolved a adolescent deep bite with crowding exclusively through roundtripping mechanics, completely bypassing IPR. Following the primary 23-stage sequence, a 5-aligner refinement was completed to fine-tune final tooth positioning, level the Curve of Spee, and detail the occlusion.
