1 | What Is Digital Smile Design (DSD)?
Digital Smile Design is a protocol that blends 2D facial photography, 3D intraoral scans, and esthetic planning software to visualize, plan, and simulate a future smile digitally before any physical treatment begins.
Originally developed for restorative dentistry, DSD is now used widely in orthodontics, allowing for treatment planning with facial harmony, midline alignment, and buccal corridor management in mind.
2 | Why Orthodontists Need DSD in 2025
- Patient-driven expectations: Millennials and Gen Z want to “see before they start.”
- Clear aligner integration: STL mock-ups directly guide staging.
- Marketing edge: “Smile simulation” boosts conversion.
- Surgical planning: Works seamlessly with orthognathic and TAD workflows.
- Motivational tool: Wax-up or 3D try-in encourages compliance.
3 | Core Workflow Steps (DSD 2D → 4D)
- Take 2D frontal high-res photo, teeth showing, relaxed lip posture.
- Upload to DSD software: Align esthetic midline, incisal plane, gingival contour using grids.
- Import CBCT + STL intraoral scan: Align to facial photo.
- Design smile: Use digital tooth libraries, mock gingival lines, buccal width adjustment.
- Preview: Create side-by-side before/after; export 4D video simulation.
- Patient approval: Add notes, versions, and timestamp.
- Export STL: For clear aligner planning, bonding guides, or try-in models.

4 | DSD + TAD / Surgical Prep Integration
DSD mock-ups can now:
- Show vector force diagrams for skeletal anchorage.
- Overlay pre- and post- SARPE width or MMA projections.
- Create 3D-printed guides for composite bonding based on approved design.
- Plan attachment placement, intrusion arcs and torque shift pre-aligner delivery.
5 | Smile Simulation & Patient Approval
Mobile-friendly 4D previews include:
- Natural animation (lip smile line in motion)
- Side-by-side previews
- QR code sharing to family / friends
- “Swipe-to-compare” web portal
Patients approve with:
- Digital signature (optional)
- Consent language built-in: “Simulation does not guarantee final result”
- Date-stamped file storage
6 | Case Logging & Integration
Element | Tool | Format |
---|---|---|
Photos | DSLR or iPhone | .jpg / .heic |
Scan | Intraoral scanner | .STL |
CBCT | Cone-beam | .DICOM |
Plan | DSD file | .dsdproj |
Video | Rendered | .mp4 or .gif |
All saved in versioned folders per patient; PDF reports are embedded into EHR or practice CRM (e.g., Cloud9, Dolphin).
7 | Billing & Insurance (US / EU)
Task | Code | Notes |
---|---|---|
Smile simulation (cosmetic) | CDT D8999 | Use as cosmetic consult |
Mock-up try-in | CDT D9930 | Record time + print cost |
Composite bonding (guided) | CDT D2330–D2335 | |
Orthognathic plan with smile overlay | CPT 21194 (adjunct note) |
In most countries, simulations are considered non-covered; best used for fee-for-service consult or upgrade cases.
8 | Red-Flag Checklist
❌ Facial photo misaligned with occlusal plane → poor 3D match
❌ Excessive overjet (>5 mm) = distorted smile sim
❌ Gingival display > 6 mm = need for lip reposition/surgery
❌ No patient consent → avoid video sharing
❌ Missing STL file = mock-up can’t be printed
9 | FAQ
What is the best DSD software?
• SmileFy, Exocad Smile Creator, DSD App, 3Shape Smile Design
• Choose based on scanner compatibility and export options.
Can I use this with braces?
Yes, especially in early planning and surgical ortho cases. Helps to visualize outcome.
How long does a DSD case take?
• 30 min with trained staff
• ~10 min export for STL and patient PDF
10 | Conclusion & PDF Workflow Card
Digital Smile Design is no longer a luxury – it’s an expectation. With integrated STL/CBCT workflows, aligner planning, and 4D visualization, DSD brings transparency, confidence, and conversion to your ortho practice.
