Gendex GX-770 - Key specifications
- 70 kVp, 10 mA maximum - delivers solid image quality for surgical planning and ortho without overexposing patients; critical for high-throughput clinics running 100+ exams weekly
- 15-second total exposure time - faster than older KaVo units, which matters when you're screening 20 kids for braces in an afternoon
- Field of view up to 21.6 cm × 8.7 cm - captures full arch including condyles in one shot, eliminating retakes that waste time and film
- Digital sensor array with 2048 × 1024 pixel resolution - direct digital output means no scanner hardware, no wet chemistry, no $800/month chemistry service calls
Gendex GX-770 price overview
You'll hit the $5K floor if tube hours are under 500 and service records are clean back 3+ years; anything over 1,200 hours or a service gap longer than 24 months drops you toward $7K–$8K. Major price swing is whether the collimator and alignment ring have been replaced - new collimator kit runs $1,400–$1,800 and buyers know it.
Buyer's checklist for Gendex GX-770
Pop the side panel and look at the tube manufacturing date stamped inside - if it's past 2018 and there's no tube replacement receipt, assume $2,500 replacement cost is coming. Check the chinrest plastic for cracks and the bite block for loose fittings; those are $300–$600 fixes that add up. Run a test pan on a phantom head with the calibration phantom they're selling it with - if contrast looks blown out or patchy, sensor's dying.
US Market overview
California and Texas are hottest right now because DSOs like Aspen Dental are consolidating smaller practices and need backup pans fast; Los Angeles metro especially sees 3–4 units move per month. Midwest markets (Kansas, Missouri) are softer because rural clinics are slower to upgrade from film.

Gendex GX-770 - FAQ
You're good to 2,000 hours if it's been serviced every 500. Past 2,500 and you're gambling - I've seen tubes crater at 2,100 and hold at 2,700. Check the service log. If it's spotty, assume you're buying a tube replacement.
Yes, the GX-770 outputs DICOM directly to any RVG-compatible software - Dexis, Schick, Planmeca Easy - no bridge software needed. Just need a network drop or USB connection. Sage Dental runs mixed film and digital in their smaller locations and it works fine.
KaVo factory service runs $180–$280 per visit plus parts. You're looking at $900–$1,200 annually for a preventative contract covering head alignment and tube inspection. Most brokers I know throw in the first alignment check free - I do.

Why buy through TechCosmetic broker?
I save clinics 6–8 weeks versus factory lead times on new equipment and handle all the HIPAA-compliant data-wipe on the hard drive so they don't inherit someone else's patient images. Typical clinic installs it themselves in 90 minutes and I'm the backup if alignment is off - that's $1,200–$1,600 in service calls you avoid.
