Digital dentistry has made intraoral scanning a routine step in everyday clinical and laboratory workflows. Yet, even with a good scanner, scan quality still depends heavily on technique. A well-structured scanning workflow can reduce chair time, minimize rescans, and improve the accuracy of downstream design and manufacturing.

Below is a practical, experience-based guide to help clinicians and dental technicians achieve consistent, high-quality scans—along with common mistakes and how to fix them.

1. Start With Proper Preparation

A smooth scan always begins before the scanner touches the patient's mouth.

Best Practices

• Dry the field adequately—moisture, blood, and saliva can introduce noise or incomplete geometry.
• Retract soft tissues effectively, either with a mirror, retraction tool, or an assistant's help.
• Check the scanner tip condition—a foggy or scratched tip will degrade accuracy.
• Seat the patient comfortably so they can remain still during the scan.

Common Errors

• Scanning without drying the occlusal surfaces
• Using a cold, foggy scanner tip
• Poor lighting or shadowing around deep molars

How to Fix

Warm the tip, apply gentle air-drying, and ensure adequate retraction before capturing the first frame.

2. Follow a Consistent Scanning Path

Experienced clinicians often emphasize one concept: consistent scanning beats fast scanning.

Best Practices

• Use a repeatable scanning strategy (e.g., occlusal → lingual → buccal).
• Maintain smooth, continuous motion—avoid abrupt stops.
• Keep the scanner at the recommended distance from the tooth surface.
• Capture full coverage of margins, especially around deep preparations.

Common Errors

• “Jumping around” the arch
• Staying too close or too far from enamel
• Missing interproximal or palatal/lingual areas
• Overlapping too much on previously scanned areas

How to Fix

Choose one scanning path and use it on every patient. Consistency reduces stitching errors and makes training easier.

3. Manage Data Quality While Scanning

Modern scanners offer real-time visualization, which makes quality control easier—as long as you actively watch the model.

Best Practices

• Check for holes, mismatches, or distorted surfaces during the scan.
• Use color visualization if available to identify under-captured prep margins.
• Rescan small sections immediately rather than relying on software fixes.

Common Errors

• Ignoring early mismatches
• Over-relying on the software's automatic repair
• Continuing a poor scan rather than restarting a quadrant

How to Fix

Pause, assess, and rescan early. A 10-second correction is better than redoing the entire arch.

4. Capture Accurate Bite Registration

Bite accuracy is one of the most overlooked steps in the scanning workflow.

Best Practices

• Ask the patient to close in maximum intercuspation (MI).
• Capture buccal bite on both sides.
• Ensure enough overlapping tooth structure between upper, lower, and buccal scans.

Common Errors

• Not enough overlap for the software to align arches
• Patient shifting during bite capture
• Capturing an eccentric bite

How to Fix

If the arches don’t align cleanly, recapture the buccal bite instead of manually adjusting in software.

5. Use AI Tools Wisely

Modern scanners—including systems like UP3D's Clariscan UP610—offer AI features such as automatic soft-tissue removal, margin enhancement, and real-time bite correction.

Best Practices

• Let AI handle repetitive clean-up tasks.
• Verify AI-trimmed areas; ensure margins are not over-trimmed.
• Use automatic stitching to reduce manual corrections.

Common Errors

• Trusting AI blindly
• Not reviewing the marginal details
• Skipping clinician validation before exporting STL/PLY

How to Fix

Think of AI as an assistant—not a substitute for clinical judgment.

6. Export and Organize Files Properly

A well-organized digital workflow minimizes miscommunication between clinics and labs.

Best Practices

• Export files in the format your lab prefers (STL/PLY/OBJ).
• Include clinical notes: prep type, shade, margin details.
• Keep file names standardized for easy retrieval.

Final Thoughts

A reliable intraoral scanning workflow reduces remakes, accelerates digital production, and increases clinician and patient satisfaction. With proper technique—and by using scanners designed for clarity and consistency—teams can achieve predictably accurate results every day.

For labs and clinics planning to strengthen their digital workflow in 2026, refining your scanning technique is one of the simplest, most cost-effective ways to elevate quality immediately.
