When shopping for an intraoral scanner, terms like "accuracy," "speed," and "color rendering" often dominate the conversation. But there’s one technical spec that plays a critical role in the scanning experience and is often overlooked: depth of field.

In UP3D’s latest intraoral scanner—Clariscan UP610—the 27±3mm depth of field sets a new standard for clinical usability. But what does that number actually mean, and how does it impact your work as a dental professional?

What Is Depth of Field in Intraoral Scanning?

In simple terms, depth of field (DOF) refers to the range of distance from the scanner tip within which objects remain in focus and are accurately captured. Think of it as the “tolerance zone” for scanning. The larger this range, the easier it is to maintain ideal scanning conditions—even when patient movement, saliva, or restricted access make things less than perfect.

A scanner with a narrow DOF requires constant distance control: too far or too close, and the image blurs or breaks. A scanner with a deep DOF, like the UP610, maintains sharp focus across a wider vertical range, which is crucial in real clinical settings.

Why UP610’s 27±3mm Depth of Field Makes a Difference

UP610’s 27±3mm DOF is one of the deepest in its class, and that extra range has real benefits during chairside workflows:

✅ Easier Access to Posterior Regions

No more tilting, adjusting, or straining to keep the scanner “just right.” Whether you're scanning molars, palatal vaults, or difficult interproximal angles, you get reliable capture even with minor hand or patient movements.

✅ Faster, More Forgiving Scans

A deeper DOF reduces rescans and scanning interruptions. The scanner doesn't lose track of data easily, allowing smoother passes and a more fluid experience—even for beginners.

✅ Better Results in Challenging Anatomies

Cases with inflamed gums, implants, or deep gingival margins require precision despite complex topography. With a wide DOF, UP610 captures these variations without losing accuracy, minimizing the need for rework.

Clinical Example: The Deep Margin Scan

Imagine scanning a case with a deep subgingival margin on a lower second molar. With a shallow DOF scanner, you must perfectly align the tip at a tight angle while staying close enough for data capture. Any small movement throws off the scan, forcing multiple retakes.

With UP610’s extended DOF, you can hover within a broader range and still get precise capture of the margin, even if soft tissue or blood slightly obstructs your view. That’s less time in the chair and less stress on both clinician and patient.

Depth of Field vs. Accuracy—Can You Have Both?

Yes. Some scanners sacrifice accuracy for deeper DOF, but UP610 balances both. It delivers:

• Full-arch accuracy of 10μm
• Fast single-arch scan time of 29 seconds
• High clarity for clinical detail—even with depth variation

This means you get flexibility and fidelity—making the scanner ideal for everything from same-day crowns to implant cases.

Final Takeaway

Depth of field may sound like a technical detail, but in practice, it's what allows you to move naturally, scan confidently, and deliver faster results without compromising quality.

The UP610's 27±3mm DOF transforms what used to be a technical challenge into a streamlined, operator-friendly experience—especially when working with real patients, not just demo models.

If you’ve ever struggled with rescans, skipped margins, or hand fatigue during long cases, it’s time to pay closer attention to DOF.
