Dental models
Diagnosis, occlusion analysis, restorative and orthodontic planning.
DENTAL / DIGITAL WORKFLOW
3D printing in dentistry
Digital dentistry from intraoral scanning and CAD to models, aligners, surgical guides and patient-specific devices.
DIGITAL DENTISTRY
From the mouth to a patient-specific device
Digital dentistry connects intraoral or CT/CBCT data with CAD and high-resolution resin printing, reducing manual work while preserving patient-specific geometry.
- 01
Capture
Use intraoral scanning or CT/CBCT where appropriate.
- 02
Design
Plan treatment and design the model or device in dental CAD.
- 03
Print
Use a validated process, resin, orientation and support strategy.
- 04
Wash and cure
Post-process for the specified time to achieve validated properties and safety.
- 05
Inspect and use
Verify dimensions, fit and traceability before clinical use.
FIVE APPLICATIONS
Dental applications of 3D printing
Clear-aligner models
Print staged models for thermoforming patient-specific aligners.
Surgical Guide
Combine CT and dental data to control implant position, angle and depth.
Crowns, bridges and dentures
Produce temporary restorations, models and patient-specific devices.
Maxillofacial
Create patient-specific maxillofacial models and prosthetic patterns.
SLA · DLP · LCD
Resin technologies used in dental labs
| Process | Principle | Strength | Examples |
|---|---|---|---|
| SLA | Laser traces each layer | Fine detail and smooth surfaces | Model · Guide · Crown/Bridge model |
| DLP | Projector exposes a full layer | Fast and batch-friendly | Aligner model · Guide · Splint |
| LCD / MSLA | LCD masks UV light | Accessible and fast | Model · Diagnostic · Orthodontic |
BIOCOMPATIBLE MATERIALS
Dental resin must match the indication
Model Resin
Prioritises dimensional accuracy and surface quality for models.
Surgical Guide Resin
Must be biocompatible, strong and compatible with a validated sterilisation method.
Splint / Night Guard
Requires bite resistance, toughness and safe intraoral contact.
Denture Resin
Designed for functional denture bases and teeth.
Temporary Crown & Bridge
For temporary restorations within the material's validated indication.
Important
Patient-contact devices require validated printers, materials, software and post-processing, used by appropriately qualified professionals.
CLINICAL VALUE
Benefits of a controlled workflow
- High accuracy and repeatability.
- Patient-specific customisation.
- Shorter production time and less manual work.
- Digital collaboration between clinic and lab.
- Digital archiving, reproducibility and traceability.
THE ACCURACY CHAIN
Accuracy belongs to the entire workflow—not one printer number
Error can accumulate through scanning, CT/CBCT registration, CAD, orientation, supports, printing shrinkage, washing, curing and sterilisation. Accuracy must therefore be evaluated on the final device after the complete process.
A small pixel or layer height does not guarantee fit when calibration, resin profile or post-curing is mismatched. Clinical workflows require a validated combination of printer, material, software and processing.
Input data
Resolution, missing areas and registration affect the design from the start.
Design
Offsets, clearances, sleeves and margins must match device requirements.
Production
Orientation, supports and profile change surface, strength and dimensions.
Post-process
Time, solvent, light and temperature must remain within the validated window.
VALIDATION & SAFETY
Control materials and traceability for patient-contact devices
- 01
Check intended use
Each resin permits different contact locations and durations.
- 02
Use a validated profile
Match printer, material version, layer height and software to the manufacturer's documentation.
- 03
Control washing and curing
Record solvent, wash cycles, temperature, time and curing equipment.
- 04
Inspect fit and surface
Remove supports and residual resin, then inspect critical areas before use.
- 05
Retain lot traceability
Link the patient, file, material, printer, operator and inspection result within the appropriate system.
Important
This is manufacturing-process information, not medical advice. Treatment planning and device use must remain under qualified professionals.
LAB CAPACITY
Plan dental-lab capacity around the indication
| Application | Critical control | Acceptance focus |
|---|---|---|
| Dental model | Arch dimensions, margins and model base | Accuracy and surface |
| Clear-aligner model | Consistency across stages and batch speed | Tooth form and thermoforming |
| Surgical guide | Biocompatibility, sleeve fit and sterilisation | Position, angle and stability |
| Splint / Night guard | Toughness, clarity and curing | Fit, edges and occlusion |
| Temporary crown / bridge | Shade, margins and approved service duration | Fit, contacts and surface |
SERVICE BUYER GUIDE
Choose a dental 3D printing provider by workflow—not unit price
Dental models, aligner models and surgical guides carry different risk. A provider should explain printer, resin, software, washing, post-cure, calibration, lot traceability and accuracy criteria. Patient-contact work requires validated materials and workflows under qualified professional oversight.
- State the indication clearly.
- Identify scanner/CAD files and units.
- Agree turnaround and repeat-production requirements.
- Define fit verification and record retention.
Important
Send a file or image with your brief so Fast 3D Print can assess process, material, lead time and price before production.
