Buying a dental lab scanner is a significant decision that affects daily productivity, restoration quality, and long-term workflow flexibility. To avoid costly mistakes, focus on the criteria that actually impact laboratory performance rather than isolated marketing claims.
Here is a clear, practical checklist of what you should look for.
1. Accuracy (Trueness + Precision)
Look for accuracy in the 6–10 μm range under ISO 12836 testing conditions.
For most crown-and-bridge and implant work, 6–8 μm offers an excellent balance. Higher accuracy reduces remakes and improves marginal fit, but only if the data is also clean and consistent.
2. Real-World Scan Speed
Brochure speeds can be optimistic. Evaluate actual performance on models similar to your daily work:
Full-arch model scan: ideally around 10–13 seconds or faster
Single arch / quadrant: under 12 seconds
Impression scan: under 25 seconds when possible
Small batches (1–4 dies): efficient cycle times
Speed only creates value when the resulting data requires little or no manual cleanup.
3. Data Quality and Software Intelligence
Inspect the output, not just the scan time. Look for:
Clean meshes with sharp margins
Minimal holes or noise
Effective AI tools (automatic incomplete-area detection, guided re-scan, implant hole closure)
True-color texture when needed for aesthetic cases
Stable, intuitive software that technicians can learn quickly
The less time spent repairing scan data, the higher the real productivity gain.
4. Versatility - What the Scanner Can Actually Handle
Confirm the scanner can digitize the objects you regularly receive:
Stone / plaster models (sectioned and unsectioned)
Impressions (direct scanning)
Dies and multi-die setups
Wax-ups
Implant scanbodies
Articulators and bite registrations
A versatile scanner reduces the need for workarounds or multiple devices.
5. Open System Compatibility
Fully open export in STL, PLY, and OBJ formats is essential.
This ensures compatibility with major CAD platforms (exocad, 3Shape, and others) and protects your ability to change or expand software and manufacturing equipment in the future.
6. Ease of Use and Learning Curve
Consider who will operate the scanner daily. Look for:
Clear, logical interface
Straightforward scanning strategies
Reliable automatic features
Short training time for new technicians
A powerful scanner that is difficult to use will not deliver its full potential.
7. Reliability, Size, and Daily Practicality
Evaluate:
Consistent performance during continuous or batch scanning
Calibration stability
Physical size and weight relative to your available bench space
Heat management and noise level
Build quality appropriate for daily production use
8. Support, Training, and Long-Term Ownership
Ask about:
Warranty terms
Technical support response times
Availability of training (initial and ongoing)
Software update policy
Expected maintenance requirements
Strong support reduces downtime and protects your investment, especially in smaller teams.
9. Total Value, Not Just Purchase Price
Compare scanners on the basis of:
Expected increase in daily capacity
Reduction in remakes
Technician time saved on scanning and data cleanup
Compatibility with your existing digital ecosystem
Long-term reliability and support quality
The lowest purchase price is rarely the highest value once productivity and quality impacts are included.
Quick Buyer's Checklist
Before making a decision, confirm the scanner offers:
Accuracy in the clinically effective range (≈ 6–8 μm preferred)
Competitive real-world full-arch speed
Clean data with minimal post-processing
Ability to scan your most common objects
Fully open file formats
Intuitive software and reasonable learning curve
Reliable daily operation and good support
Clear total value relative to your volume and case mix

Final Advice
Request sample scan data or a demonstration on models similar to your daily cases. Measure the total time from placing the object to having a clean, design-ready file. Involve the technicians who will use the scanner every day.
The right dental lab scanner should improve throughput, protect restoration quality, and integrate smoothly into your workflow without creating new bottlenecks.
