Technology

The materials, the planning, and the production behind every Smarty case.

Clear aligners are only as good as the science behind them. Here is exactly what is in our trays, how we plan movements, and how we manufacture each set.

Material

Shape-memory resin, 3D directly printed.

Our aligners are 3D directly printed from a medical-grade shape-memory resin. Each tray is grown to its planned geometry and self-corrects toward that shape at oral temperature, delivering more predictable, sustained force across every stage.

  • · Directly printed in one continuous structure — no model, no waste
  • · Shape-memory recovery activated at body temperature
  • · BPA-, phthalate- and latex-free
  • · FDA 510(k) cleared base resin

Directly printed, programmed to move

Each tray is a single, continuously-printed shape-memory structure — no model, no waste.

Treatment planning

A 3D plan you can actually interrogate.

Every plan is annotated stage-by-stage. You see tooth-level movement vectors, IPR locations, attachment placement and over-correction strategy — and you can ask for revisions before a single tray is printed.

  • · Movement budget capped at 0.25 mm and 2° per stage
  • · Attachment library with engineer-validated geometries
  • · Annotate any stage; we re-plan within 24 hours
  • · Final ABO-style assessment auto-generated
Manufacturing

Printed, polished and inspected — every single tray.

1 · Direct 3D print

Each tray is printed directly in shape-memory resin to ±50 µm tolerance — no stage model needed.

2 · UV post-cure

Trays are washed and UV-cured to lock in the shape-memory baseline geometry.

3 · Trim & polish

Robotic trim to scalloped gingival margin, then hand polish for comfort.

4 · QC inspection

Every tray inspected for fit, fracture lines and stage labeling before shipment.

Compliance

Patient data treated as carefully as patient teeth.

Smarty Aligners is HIPAA- and GDPR-compliant. Patient records, scans and X-rays are encrypted in transit (TLS 1.3) and at rest (AES-256). Access is granular: associates, hygienists and front-desk staff see only what they need.

HIPAA

Business Associate Agreement available on every clinic plan.

GDPR

EU data residency. Patient export & deletion on request.

ISO 13485

Quality management system audited annually.

SOC 2 Type II

Security & availability controls independently verified.
