Where the Gendex GXCB-500 HD stands today
- Resolution is solid mainstream (125µm at best). Fine for implant visualization; the newest high-res units go finer, but the real-world difference is marginal for case communication.
- Field of view reaches 14cm — enough for both arches in one capture. Most practices never switch out of the small default FOV and never know they have this.
- It's 16 years old (2010) — legacy hardware. The question isn't "is it old," it's "does a networking/software path get you current for a fraction of a new unit." Usually yes.
- Detector: a-Si flat panel (i-CAT-powered), CsI; adds i-Pan 2D pan capture tech.
- This model is no longer sold new (succeeded by the i-CAT FLX / KaVo platform (no direct in-line Gendex 3D successor)) — which means parts, service, and software support are the thing to verify before any new spend.
What it already does that most practices don't use
- Output/networking: DICOM export; i-CATVision / open architecture. That export path is what lets a scan leave the machine and become something a patient can actually look at.
Upgrade paths for the Gendex GXCB-500 HD
- UpgradeAdjustable 3D medium FOV; open architecture for CAD/CAM; reconstructs 2D pan from 3D volume
- SuccessorThe i-CAT FLX / KaVo platform (no direct in-line Gendex 3D successor) is the current successor — useful as a yardstick for what actually changed, not an automatic reason to buy it.
- NetworkThe fastest upgrade is almost never new hardware — it's getting the volume off the machine and into a workflow. That alone changes what the box is worth to you.
- ReconfigureSwitching your default to the right FOV/scan mode for implant cases is free, and most practices never do it.
Repair vs. replace: what it costs
Repair: the dominant wear item on any dental CBCT is the X-ray tube — a replacement runs roughly $15,000-$40,000, typically every 3–7 years depending on scan volume. A larger-FOV unit like this one sits toward the upper end of that range. Budget a service contract at about $5,000–$15,000/year and software licensing around $2,000/year. A flat-panel detector is the big unknown — it isn't publicly priced, so get a manufacturer quote before assuming the worst.
Parts & service (legacy unit): because this model is no longer sold new, parts and service availability — not the sticker — decide whether a repair is worth it. Confirm both before any spend.
Replace: a comparable unit runs roughly No MSRP; used/reseller ~$15k-$40k. The honest test before spending that is whether a networking or software path gets you most of the capability for a fraction of it — for an aging machine, it usually does.

Gendex GXCB-500 HD — common questions
- Can Alvea use scans from the Gendex GXCB-500 HD?
- Yes. The Gendex GXCB-500 HD exports a standard DICOM volume, and Alvea converts that volume into a chairside 3D model of the patient's jaw — no new hardware and no new scan. It runs off the cone-beam you already take.
- Is the Gendex GXCB-500 HD discontinued, and what replaced it?
- The Gendex GXCB-500 HD is no longer sold new; its successor is the i-CAT FLX / KaVo platform (no direct in-line Gendex 3D successor). An aging unit is rarely a reason to replace on its own — parts, service and a software/networking path usually keep it clinically current for far less than a new machine.
- How much does a Gendex GXCB-500 HD cost?
- A comparable Gendex GXCB-500 HD runs roughly No MSRP; used/reseller ~$15k-$40k. Before replacing, weigh whether a networking or software path gets you most of the capability for a fraction of that.
- How much does it cost to repair a Gendex GXCB-500 HD?
- The dominant repair on any dental CBCT is the X-ray tube, which runs roughly $15,000-$40,000 and is typically replaced every 3–7 years by scan volume. Annual service contracts run about $5,000–$15,000, and a flat-panel detector is quoted by the manufacturer rather than listed publicly. These are 2025–26 industry ranges, not a quote for a specific unit.
- What is the field of view on the Gendex GXCB-500 HD?
- The Gendex GXCB-500 HD reaches 14 cm, enough to capture both arches in one scan — a mode most practices never switch to.
