Where the Dentium Rainbow CT stands today
- Field of view reaches 17.5cm — enough for both arches in one capture. Most practices never switch out of the small default FOV and never know they have this.
- At 10 years (2016) it's aging but not obsolete. This is exactly the window resellers target for a trade-up you may not need yet.
What it already does that most practices don't use
- The same unit does panoramic/ceph as well as 3D — one capture surface you may be sending out for.
- Output/networking: standard DICOM export. That export path is what lets a scan leave the machine and become something a patient can actually look at.
Upgrade paths for the Dentium Rainbow CT
- Upgrade3-in-1 (CBCT + pano + ceph); largest FOV up to 17.5x15 via stitching; 240-degree low-dose scan.
- 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.
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.

Dentium Rainbow CT — common questions
- Can Alvea use scans from the Dentium Rainbow CT?
- Yes. The Dentium Rainbow CT 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.
- How much does it cost to repair a Dentium Rainbow CT?
- 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 Dentium Rainbow CT?
- The Dentium Rainbow CT reaches 17.5 cm, enough to capture both arches in one scan — a mode most practices never switch to.
