Owandy's Opteo Adds a Size 1.5 Sensor. Check Your Sleeves First.

Owandy Radiology's third-generation Opteo intraoral sensor was announced in October 2025. Most of the coverage is about image quality. For the person who runs the operatory, one detail matters more: the range now includes a new size 1.5, next to the existing sizes 1 and 2. A new sensor size is a reason to check your barrier supply before the first patient, not after.

What the sources say

Trade reports from Dentistry Today and Dentistry33 describe the same launch:

• a new size 1.5 that, according to the company, captures up to four teeth in one image, added to sizes 1 and 2
• 18.5-micron "Ultra HD" resolution
• wide dynamic range processing that adjusts to different exposure levels, which the company says should reduce retakes
• an "Always On" function with no warm-up time
• a direct USB connection for one or several workstations
• a CMOS chip, fiber optics and a shock-absorption system

Orthodontic Products reports the same specifications and gives no detail on the cable or housing. The sources we read also do not say when the sensor reaches European dealers, so check availability with your own supplier.

Why a new size touches your barrier routine

The CDC's page on sterilization and disinfection says digital radiography sensors are semicritical items. It says they should be protected with an FDA-cleared barrier to reduce contamination during use, and that if an item cannot tolerate heat sterilization or high-level disinfection, you should at a minimum protect it with such a barrier. It also says these items vary by manufacturer, so reprocessing follows the manufacturer's instructions. The CDC page is here.

The CDC wording is US guidance. In the EU, the same practical logic applies, but the rules that bind you are your national requirements and the sensor maker's instructions for use. Read those before you decide how the sensor is covered and reprocessed.

None of the sources we fetched gives the outer dimensions of the size 1.5 sensor or its cable. So we cannot tell you which sleeve fits it. What we can say is what to check.

Monday-morning checklist

1. Read the instructions for use. Find the cleaning, disinfection and barrier instructions for the new sensor. If your practice keeps a protocol for sensors, the new size goes into it by name.
2. Ask for dimensions, not "universal". Ask your sleeve supplier whether the exact sensor size and cable are listed as compatible. Do not rely on a general claim.
3. Test one sleeve before the patient. Fit it on the sensor and check three things: the sensor sits fully inside, the cable is covered as far as your protocol requires, and nothing is stretched thin at the corners.
4. Brief the team. A size 1.5 sensor is easy to mix up with sizes 1 and 2 in a drawer. Label the sizes and put the matching sleeve and positioning accessories next to them.
5. Keep a spare. If a sleeve tears during placement, you need a second one within reach, not a trip to the store room.

Positioning accessories are touched too

A sensor is rarely placed by hand alone. Bite blocks and holders go into the mouth with it and are handled by the same gloved hands. If your protocol covers the sensor but not these items, the new sensor is a good moment to close that gap.

What does not change

A better sensor does not remove the need for a barrier. Higher resolution and fewer retakes are image-quality claims. They say nothing about how you protect the sensor from saliva and blood, or how you reprocess it. That part stays with your protocol and the manufacturer's instructions.
