Few patients enjoy having a tray of impression material pressed against their teeth. Intraoral scanners replace that tray with a small wand that captures a 3D digital model of the mouth in minutes. Once a niche purchase, scanners are now common in Australian practices, and many dental labs prefer digital files to physical impressions.
If you're considering a scanner, this guide covers what they do, the business case, costs, how to choose one and how to make it pay its way.
This article is general information for practice owners. It isn't clinical advice.
Key takeaways
- Intraoral scanners capture a 3D digital impression that can be sent straight to a lab or used for in-house manufacturing.
- The main benefits are patient comfort, faster lab turnaround, fewer remakes from distorted impressions, and better patient communication.
- Costs include the scanner, software subscriptions, training, and time for the team to become proficient.
- Open vs closed file formats and lab compatibility are among the most important buying questions.
- Scanners pay off fastest when they're used daily, not just for crowns.
What an intraoral scanner does
A scanner uses a camera in the wand to capture thousands of images as it moves around the mouth. Software stitches them into an accurate 3D model, displayed on screen in real time. The file can then be:
- Sent to a dental lab for crowns, bridges, veneers, implant restorations or appliances
- Used for clear aligner planning
- Used with chairside milling or a 3D printer
- Saved as a record to monitor wear, recession or tooth movement over time
- Shown to the patient to explain their situation
The business case
Patient experience
No impression trays means less gagging and discomfort, which patients notice and often mention to friends. For anxious patients and children, that matters.
Fewer remakes and faster turnaround
Digital files can't be distorted in transit, bubbles can be fixed by rescanning a single area, and the file reaches the lab instantly. Many practices find this reduces remakes and shortens the time between preparation and fitting.
Lower consumable costs
You'll use less impression material, fewer trays and less courier time, though these savings are partly offset by software and tip costs.
Case acceptance
Showing patients a large, rotatable 3D model of their own teeth can help them understand wear, cracks or crowding. Keep explanations accurate and avoid overstating outcomes.
New services
Scanners make it easier to offer clear aligners, night guards, sports mouthguards and in-house appliances, if they fit your practice.
Costs to plan for
- Hardware: the scanner itself, bought outright, financed or leased. Prices vary widely by brand and model.
- Software: many scanners have ongoing licence or subscription fees, sometimes bundled with cloud storage and lab connections.
- Tips and accessories: reusable or single-use scanning tips, plus their reprocessing.
- Computer: some systems need a dedicated, powerful computer or cart.
- Training: initial training and practice time for clinicians and assistants.
- Lost time early on: scans are slower until the team is proficient.
Ask vendors for the total cost over five years, not just the headline price.
How to choose a scanner
Open or closed files
An open system exports standard files such as STL, PLY or OBJ that any lab or software can use. A closed system may only work with specific labs, software or the manufacturer's own ecosystem, or charge extra to export. Open systems give you more freedom; closed systems can offer smoother workflows within their ecosystem.
Lab compatibility
Ask your main labs which scanners they accept and prefer, and how they receive files.
Speed and ease of use
Try several scanners hands-on. Wand size and weight, scanning speed, how it handles moisture and saliva, and the software's ease of use all matter.
Accuracy for your work
For full-arch cases, implants or long-span bridges, check independent accuracy evidence relevant to those indications.
Integration
Check how scans link to patient records in your practice software and imaging system.
Regulation and infection control
Intraoral scanners are medical devices, so confirm the model is included in the ARTG. Follow the manufacturer's instructions for reprocessing tips and cleaning the wand, in line with your infection control obligations.
Data and privacy
Scans are health information. If they're stored in the cloud, check where and with whom. See patient data and AI vendors.
Making it pay off
- Scan routinely, not only for crowns: new patient records, wear monitoring and appliances all build proficiency.
- Delegate where appropriate. Trained dental assistants, hygienists and therapists may take scans within their scope, freeing dentist time.
- Set up lab workflows so files go out the same day.
- Track results: remakes, turnaround time and treatment acceptance before and after.
Frequently asked questions
Are intraoral scans as accurate as traditional impressions?
For many indications, research shows digital impressions are comparable to conventional ones. Accuracy depends on the scanner, the operator and the type of case, especially for full arches.
Can my dental assistant take scans?
Depending on their training and the scope of practice that applies, team members may take scans. Check the Dental Board of Australia's scope of practice guidance and your indemnity insurer's advice.
Should I buy a scanner or a milling unit first?
Most practices start with a scanner, because it works with their existing labs. Milling or printing can come later.
Next steps
Book hands-on demos with two or three scanner brands, and ask your labs which they prefer. For more on going digital, read about chairside 3D printing and what's worth adopting in 2027. For the front desk side of a modern practice, see how IntelliDent's AI agents handle calls and bookings.
