Why This Comparison Matters

Many practices did not switch to the DEXIS IXS all at once. They added one or two sensors while older Gendex GXS-700 sensors kept working in other operatories. DEXIS describes the IXS as "the new and improved Gendex", built on decades of experience with the GXS-700. Understanding what changed, and what stayed the same, helps you handle, store and service a mixed fleet correctly.

What DEXIS Changed

Durability

DEXIS says the IXS is more resistant to damage and functional failure than the GXS-700, and handles more bite force without cosmetic damage, based on simulated testing. DEXIS credits its DEXISTough engineering and a thermoplastic resin housing with a dome surface that protects the internal components.

The cable

DEXIS describes the IXS cable as using a copper alloy inner shield and aramid-reinforced strands, fused directly to the USB housing, and states it is designed to never need replacing. That is a manufacturer design goal, not a guarantee against damage from crushing, cutting or sharp bends.

Calibration and set-up

With the IXS, DEXIS stores calibration files inside the sensor. Once drivers are installed, the sensor downloads its calibration automatically when plugged in, so it can move between operatories without manual calibration file handling.

Smart monitoring

DEXIS lists SimplySmart IoT capabilities: automated software updates and proactive sensor health monitoring through DEXIS Software Manager.

How the IXS Captures an Image

DEXIS explains the IXS imaging chain in some detail. A scintillator converts X-ray photons into visible light, a protective fiber optic plate guides that light to the CMOS pixels, and the pixels convert it into electrical signals that are digitized into the image. Knowing this helps explain why internal damage can show up as image artifacts that no software setting can fix.

What Carries Over

DEXIS states that the IXS positioning system, including bitewing, anterior and posterior holders, is backwards compatible with GXS-700 sensors. That makes it easier to standardise holders across a mixed fleet. DEXIS also describes these holders as engineered to withstand bite force and repeated autoclaving.

Side-by-Side Summary

Topic	Gendex GXS-700	DEXIS IXS
Relationship	Earlier generation	Described by DEXIS as the new and improved Gendex
Durability	Baseline for DEXIS comparison	More resistant to damage and bite force, per DEXIS testing
Cable	Earlier design	Reinforced, fused to USB housing, designed to never need replacing
Calibration	Earlier workflow	Stored in the sensor, downloads automatically
Sizes	Check the sensor label	Two RiteSize options: size 1 and size 2
Holders	Original system	New positioning system, backwards compatible with GXS-700

What the Differences Mean for Service

Identify the model clearly. IXS and GXS-700 sensors can look similar in a busy operatory. Label each sensor and note its size.
Check coverage first for IXS. DEXIS lists an unconditional first-year warranty with next-day replacement for performance issues, plus the DEXIS Complete plan for the life of the product.
Expect different failure patterns. Because DEXIS reinforced the IXS cable and housing, problems are more likely to come from software, drivers or USB ports than on older sensors, but physical damage can still happen.
Do not swap calibration files manually on an IXS. DEXIS designed calibration to download automatically from the sensor.

Should You Replace GXS-700 Sensors With IXS?

That depends on the condition of your existing sensors and how your practice uses them. A GXS-700 that still captures reliable images may not need replacing just because a newer model exists. A GXS-700 with repeated cable or housing problems may be a better candidate for replacement, or for an independent repair assessment if it is out of coverage.

Questions worth asking include: how often has this sensor needed attention, does it still produce consistent images, and how much downtime would a failure cause? There is no single right answer, which is why Repair.Dental does not recommend upgrading or repairing by default.

Common Mix-Ups in Mixed Fleets

Assuming every sensor needs the same set-up. IXS calibration downloads from the sensor; follow DEXIS guidance for each model.
Using the wrong size in software. IXS comes in size 1 and size 2, so confirm the correct one is selected when images look wrong.
Blaming the newest sensor first. When problems appear in one room only, check that room's computer and driver before suspecting the IXS.

Mixed-Fleet Tips

Label each sensor with model and size.
Use the IXS positioning system across both models where it fits, since DEXIS lists it as GXS-700 compatible.
Install the DEXIS IO Sensor Driver on every computer an IXS might be plugged into.
Keep a simple log of which sensor lives in which operatory, and any problems seen.

Next Step

If an IXS is still within DEXIS coverage, contact DEXIS first. For an out-of-coverage IXS or an older GXS-700 with physical damage, talk to the Repair.Dental team or start a repair. Our DEXIS sensor troubleshooting guide covers checks to try first.
