1 | Why compare now?
LiDAR scans, cloud GPUs and FDA-cleared AI engines cut plan-making time from 45 min to < 5 min. But reproducibility isn’t everything: occlusal nuance, periodontal limits and patient-specific goals still rely on human judgment.
2 | Speed test
| Task | AI-only (DentalMind PlanX) | Human Ortho (avg) |
|---|---|---|
| Import STL & segment | 20 s | 4 min |
| Setup goals (Class I, OB/ OJ) | Auto | 5 min |
| Tooth-move staging | < 1 min | 15 min |
| Force-check & collision fix | Auto iterate | 12 min |
| Total | < 5 min | ≈ 40 min |
3 | Accuracy metrics
| Parameter | AI | Human | Notes |
|---|---|---|---|
| Prediction RMSE (tip/torque) | 0.27 mm / 0.32 ° | 0.31 mm / 0.35 ° | AI edges human slightly |
| Mid-course refinement rate | 14 % | 18 % | Human updates on chair-time limits |
| Case acceptance speed | +37 % | Baseline | Faster 3-D preview sells aligners |
4 | Scope differences
- AI engines: aligner-only at present; braces need bracket prescription logic.
- Humans: can mix appliances, extractions, TADs and surgery forecasting.
Hybrid approach: AI makes baseline; orthodontist tweaks biomechanics (e.g., power-ridge, attachments).
5 | Clinical oversight & ethics
FDA mandates “licensed clinician in loop” for AI medical devices. Neglecting review triggers liability; 2024 lawsuit (Smith v. QuickAlign) settled at US $950 k for root resorption missed by auto-plan.
6 | Cost analysis
| Model | Cost/plan | Chair-time saved | ROI /100 cases |
|---|---|---|---|
| Human-only | US $0 software, 40 h | — | — |
| AI SaaS (US $50/plan) | US $5 000 | 65 h chair freed | Est extra 24 starts (@US $5 k each) → +US $115 k |
7 | Hybrid workflows
- AI draft → clinician refinement (most common)
- Parallel review: AI & human plans compared; merge best moves.
- AI for aligners + human for fixed finishing (combo cases).
8 | Red-flag checklist
- ❌ No human sign-off in the PDF plan
- ❌ AI can’t handle impacted canines or skeletal asymmetry
- ❌ Force budget shows > 2 N on short roots
- ❌ Patient has perio pockets > 4 mm (need periodontal clearance)
9 | FAQ
Does AI replace my orthodontist?
No—regulation demands clinician oversight; think “autopilot,” not pilot replacement.
Is AI cheaper?
Yes per plan, but only when practice volume offsets subscription.
What about data privacy?
BAA-compliant cloud hosting; export anonymised STL if concerned.
10 | Conclusion & decision matrix
AI planning shines on speed and repeatability; humans excel in complex judgment and ethical accountability. Hybrid beats either alone for most 2025 clinics.
Choose AI + human if: mild-moderate aligner case, speed matters.
Choose human-led if: extractions, braces, perio issues, or surgery.
