DEXIS Put a Number on How Many Times You Can Autoclave a Scanner Tip

Why this matters now

In March 2026, DEXIS announced that the Institute of Digital Dentistry named its Imprevo intraoral scanner the 2025 Most Improved Intraoral Scanner, crediting a year of changes that included a smaller scan tip. Independent coverage from DrBicuspid confirmed the recognition and reported that the smaller tip was designed to improve patient comfort and reduce scan time. DEXIS's own product page goes further: it now lists a standard tip and a new slim tip, swappable mid-scan to reach posterior teeth and tight spaces.

The award isn't the interesting part. What DEXIS does, and doesn't, publish about reusing that tip is — and it's a useful prompt to ask the same question about everything else in the practice marked "autoclavable."

What actually changed

DEXIS's specification page states a reuse limit for the standard Imprevo tip:

• Hygiene cycle (134°C, 4 minutes): up to 160 cycles
• Extra hygiene cycle (134°C, 18 minutes): up to 100 cycles

Two different ceilings for the same tip, depending on which cycle the sterilizer runs. That detail matters more than the numbers themselves: a reuse-life figure is tied to specific sterilizer parameters, not a flat lifetime stamped on the device.

The new slim tip carries no equivalent figure on that page. It's described by its fit and its mid-scan swap feature, not by how many autoclave cycles it can take before it needs replacing.

That's the exact gap FDA's 2015 guidance on reprocessing addresses. In the section on reuse life, the guidance states that device labeling should either tell the user how many times a device can be reused, based on testing, or give a method to check whether the device has exceeded its use life — and if a specific cycle count is stated, the labeling should also describe how to track that count. It adds that the number assumes full compliance with the device's directions for use.

FDA doesn't fix a cycle count for any device category. It sets a disclosure requirement: give the user a number, or give them a way to check.

What this means in the operatory

If your practice adds the slim tip, don't assume it shares the standard tip's cycle limit. Ask DEXIS or your supplier for the slim tip's own figure, the cycle parameters it was tested against, and how you're meant to log the count per tip — sticker, barcode, paper log. That tracking method is part of what the guidance expects alongside the number itself.

The same question is worth asking about anything else labelled autoclavable rather than single-use: reusable bite block assemblies, impression trays, anything with a lumen. "Autoclavable" describes what a material can withstand, not how long a specific unit is good for. If a supplier can't give you a cycle count or a documented way to check for wear, that's a gap in their instructions for use — not a reason to assume the device is fine indefinitely.

Devices you cover with a single-use barrier instead don't raise this question. A sleeve discarded after one patient has no cycle count to track, because it never goes through a second cycle.

What to check

• Does the instructions for use for each reusable intraoral device state a maximum reprocessing cycle count or a documented wear-check method?
• If a count is given, does it match the sterilizer cycle you actually run — temperature and time — not just a cycle name?
• Is there an agreed way to log cycles per individual tip or instrument, not just per device model?
• For anything your supplier can't answer clearly, would a disposable barrier remove the question instead?
