Where the Gendex GXDP-700 stands today
- Resolution holds up: at its sharpest (85µm voxel) it's still in the fine-detail tier the newest units sell on. You are not behind on image quality.
- Field of view tops out at 8cm — single-arch range. Good for localized implant work; whole-jaw cases need the larger-FOV path (below).
- It's 15 years old (2011) — 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: CMOS flat-panel detector; 0.5 mm focal spot (IEC 60336); high-frequency DC generator 75-150 kHz; min filtration 3.2 mm Al.
- This model is no longer sold new — 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
- Multiple FOV modes (4x6 cm (approx d x h), 8x6 cm, 61x41 mm (h x d), 61x78 mm (h x d)). Most operators leave it on one preset — the larger modes are already paid for.
- The same unit does panoramic/ceph as well as 3D — one capture surface you may be sending out for.
- Output/networking: DICOM export (yes). 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 GXDP-700
- UpgradeFully modular: purchased as a 2-D digital panoramic unit and field-upgradeable to add cephalometric and/or 3-D small-FOV (SFOV) Cone Beam CT, or both ('pay as you grow')
- 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. 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: replacement pricing varies by configuration and condition. Before any trade-up, the honest test is whether a networking or software path gets you most of the capability for a fraction of a new unit.

Gendex GXDP-700 — common questions
- Can Alvea use scans from the Gendex GXDP-700?
- Yes. The Gendex GXDP-700 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 GXDP-700 discontinued, and what replaced it?
- The Gendex GXDP-700 is no longer sold new. 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 it cost to repair a Gendex GXDP-700?
- 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 GXDP-700?
- The Gendex GXDP-700 reaches 8 cm, single-arch range suited to localized implant work.
