A well-designed digital dentistry workflow begins with an accurate intraoral scan and continues smoothly through design, manufacturing, and final delivery. When each step is connected properly, clinics gain faster turnaround, better-fitting restorations, improved patient experience, and greater control over quality.
This guide outlines the complete digital workflow using intraoral scanners and explains how to build it effectively.
1. The Core Digital Workflow Overview
A typical intraoral scanner-based digital workflow follows these stages:
Patient scanning (intraoral scanner)
Data review and preparation
Design (CAD software - in-clinic or laboratory)
Manufacturing (milling or 3D printing - in-clinic or laboratory)
Finishing, quality control, and delivery
Documentation and follow-up
The intraoral scanner is the critical first step. The quality of the digital impression determines the success of everything that follows.
2. Step 1: Intraoral Scanning (Data Capture)
Goal: Capture complete, accurate, and clean digital impressions of the prepared teeth, surrounding tissues, opposing arch, and bite.
Best practices:
Isolate and dry the area as needed
Capture all critical surfaces, especially preparation margins
Scan the opposing arch and a reliable bite registration
Review the 3D model in real time and rescan missing areas immediately
Ensure soft tissues and margins are clearly visible
Key scanner capabilities that support this step:
High accuracy (≤10 μm or better)
Powder-free operation
Effective anti-fog technology
Sufficient depth of field
Fast frame rate and smooth scanning
True-color imaging
Open export (STL, PLY, OBJ)
Aident example performance:
AI-30: ≤10 μm, 156–198 g, ≥30 fps
AI50: ≤7 μm, 145 g (with tip), 38 fps, AI smart report
3. Step 2: Data Review and Case Preparation
Before design begins, the digital model should be checked for:
Complete margin definition
Adequate data on contact areas and emergence profile
Correct bite alignment
Absence of major holes, noise, or distortion
Proper file integrity and scale
Clean data at this stage prevents most downstream problems and remakes.
4. Step 3: Design (CAD)
Digital models are imported into CAD software for restoration design.
Two common paths:
| Path | Description | Best For |
|---|---|---|
| In-clinic design | Dentist or in-house designer uses chairside CAD | Same-day or rapid turnaround cases |
| Laboratory design | Scan data sent to a dental laboratory | Complex cases, high volume, or when lab expertise is preferred |
Popular CAD platforms that work with open intraoral scan files include exocad, 3Shape, and others. Open STL/PLY/OBJ export from the scanner preserves maximum flexibility.
Design includes margin marking, virtual die creation, restoration modeling, occlusion adjustment, and final preparation for manufacturing.
5. Step 4: Manufacturing (CAM)
The approved design is sent to a manufacturing system:
Milling - Common for zirconia, glass ceramics, hybrid materials, and PMMA
3D printing - Increasingly used for models, surgical guides, try-ins, temporaries, denture bases, and some final restorations
Manufacturing can occur:
In the clinic (chairside or same-day workflow)
In a partner dental laboratory
Through a centralized production center
Open digital files allow clinics to choose the most suitable manufacturing partner or equipment without being locked into one ecosystem.
6. Step 5: Finishing, Quality Control, and Delivery
After manufacturing:
The restoration is finished, stained, glazed, or polished as required
Fit, contacts, and occlusion are verified (on a printed model or digitally)
Final quality checks are performed
The restoration is delivered to the patient
Digital workflows often reduce the number of adjustments needed at the chair because the original scan data was more accurate and complete.
7. Supporting Elements of a Successful Digital Workflow
Open Architecture
Using scanners and software that support standard open formats prevents vendor lock-in and gives clinics freedom to change CAD or manufacturing partners as needed.
Team Training
Dentists, assistants, and any in-house designers must be trained on scanning technique, data quality criteria, and software workflows. Consistent protocols reduce variability.
Clear Communication with Laboratories
When working with external labs, establish preferred file formats, naming conventions, prescription details, and feedback loops for continuous improvement.
Quality Checkpoints
Build simple checks at scanning, design approval, and pre-delivery stages to catch issues early.
Data Management
Organize digital files systematically and maintain reliable backups.
8. Same-Day vs Laboratory-Supported Workflows
| Workflow Type | Advantages | Considerations |
|---|---|---|
| Same-day / Chairside | Fastest delivery, single-visit dentistry | Requires in-clinic design and manufacturing equipment plus trained staff |
| Lab-supported | Access to specialist expertise and broader material options | Depends on lab turnaround time and communication quality |
| Hybrid | Flexibility to choose per case | Requires clear decision criteria and reliable digital handoff |
Most clinics benefit from a hybrid approach as they grow their digital capabilities.
9. Common Pitfalls and How to Avoid Them
Incomplete scans → Enforce real-time review and immediate rescanning
Poor margin visibility → Improve isolation and scanning technique
File incompatibility → Use open-export scanners and confirm lab/CAD requirements
Inconsistent results between operators → Standardize protocols and training
Over-reliance on technology without process discipline → Combine good equipment with clear clinical protocols
10. Building Your Digital Workflow: Practical Roadmap
Select a reliable, open intraoral scanner suited to your case mix.
Train the clinical team on scanning technique and data quality.
Decide which cases will be designed/manufactured in-clinic vs sent to a laboratory.
Establish clear digital prescription and file-handoff processes with partners.
Start with higher-volume, straightforward cases (e.g., single crowns) and expand.
Monitor fit quality, adjustment time, and turnaround metrics.
Continuously refine protocols based on real results.
