Digital dentistry has advanced rapidly, yet many clinicians still hear—or believe—misconceptions about intraoral scanners. Some of these myths date back to early-generation scanners, while others arise from unfamiliarity with current technology.
To help you make informed decisions, this article clarifies the most common myths and explains what today's scanners can actually deliver.

Myth 1: “Intraoral scanners are less accurate than traditional impressions.”

This misconception is largely outdated. Multiple independent studies now show that modern intraoral scanners can achieve accuracy equal to—or in many cases better than—conventional impressions, especially for:

• Single-tooth restorations
• Short-span bridges
• Implant cases
• Orthodontic analysis

Accuracy continues to improve with:

• More advanced optics
• Better AI-driven stitching algorithms
• Real-time model optimization
• Stable scanning paths recommended by manufacturers

Traditional impressions still have a place, but digital accuracy today is highly reliable and consistent.

Myth 2: “Scanners struggle with full-arch accuracy.”

Early scanners did face challenges with full-arch scans due to accumulated stitching errors.
Today, however, full-arch accuracy has significantly improved thanks to:

• Wider field-of-view optical systems
• Deeper depth of field (DOF)
• Optimized scanning strategies for arches
• AI correction for drift and stitching misalignment

Full-arch scanning remains more technique-sensitive than single-unit scanning, but with proper training and stable scanning patterns, clinicians achieve predictable full-arch results daily.

Myth 3: “Intraoral scanning takes longer than traditional impressions.”

In reality, digital workflows save time in nearly every stage:

Chairside:

• No mixing, setting, trimming, disinfecting
• Real-time visualization reduces retakes
• AI helps automatically clean soft tissue noise

Laboratory workflow:

• Immediate digital transfer
• No shipping delays or impression distortions
• CAD design starts instantly

Many clinics report that digital scans reduce appointment time, especially when capturing multiple units or sending cases to remote labs.

Myth 4: “Scanners are difficult to learn and require extensive training.”

Modern scanners are designed to be intuitive. Most clinicians can scan confidently after a short onboarding period.
User-friendly features now include:

• Real-time margin visualization
• Automatic detection of missing areas
• AI-guided scan paths
• Simple file exporting to all major CAD systems

New-generation scanners like the Clariscan UP610 also offer motion-sensing navigation and a clear interface that shortens the learning curve even further.

Myth 5: “Digital impressions don't work well with wet surfaces or reflective materials.”

Moisture and reflectivity can affect scan quality—but only if not managed properly.
Modern scanners use:

• Improved anti-reflection algorithms
• Optimized illumination systems
• AI noise filtering
• Wider dynamic range sensors

As long as the field is isolated (the same way you would before taking an impression), scanners capture surfaces accurately without needing powders or sprays.

Myth 6: “Digital files aren't compatible across different systems.”

Most scanners support open file formats such as:

• STL (standard geometry)
• PLY (color + texture)
• OBJ (color mesh with detailed shading)

These files integrate smoothly with mainstream CAD/CAM platforms, 3D printers, and milling systems.
Closed systems still exist, but the industry is moving decisively toward open workflows.

Myth 7: “Scanners are too expensive and only for large clinics.”

While early scanners were costly, prices have become far more accessible, especially with lower maintenance requirements and fewer consumables.
Digital workflows also reduce long-term expenses related to:

• Impression materials
• Shipping
• Retakes
• Storage
• Manual labor

Most clinics recover their investment faster than expected—sometimes within months—especially if the scanner is actively used for restorative, orthodontic, and implant workflows.

Myth 8: “You still need traditional impressions for many cases.”

In the past, certain cases—such as edentulous arches, deep subgingival margins, or implant scans—required analog impressions.
Now, with enhanced optical systems and scan bodies, many of these cases can be fully digital:

• Edentulous scanning with tissue capture
• Deep margin detection with AI enhancement
• Implant-level scans with precise geometry recognition
• Full-arch implant scanning with accurate stitching algorithms

Analog impressions remain an option, but digital-first workflows are increasingly becoming the standard of care.

Final Thoughts

Intraoral scanners have evolved dramatically, and many common myths no longer reflect modern technology.
Understanding the realities behind these misconceptions helps clinicians select the right scanner, streamline workflows, and deliver high-quality restorations with confidence.

As scanners continue to improve—with better optics, smarter software, and AI-enhanced functionality—the shift toward digital dentistry will only accelerate.

If you want a future-ready digital workflow, investing in a reliable scanner today is one of the most meaningful upgrades a clinic can make.
