Planmeca · Dental Equipment · $3,500 – $7,000
Used units run $3,500–$7,000 depending on whether the sensor still has intact protective coating and cable sheath; a unit with surface scratches on the sensor face or a kinked cable drops $1,500–$2,000 instantly because replacement sensors cost $2,800–$3,400. Service history gap over 12 months or longer usually means calibration's drifted and you're buying a $600 recalibration job right out of the gate.
Plug it in and shoot three test images on a step-wedge aluminum block - you should see clean separation between steps 6 and 7; if contrast is washed out, the sensor's dying. Check the cable connector at the sensor head for loose pins (hold it up to light and look through) and run your finger along the protective sheath for cracks where moisture creeps in. Ask for the last three months of sensor error logs from the clinic's software - repeated dropouts or gray-frame errors mean the USB port is failing.
California and Texas chains are aggressive buyers right now because they're replacing older Schick models that Dexis sunsetted support for; Heartland Dental in the Midwest is also cycling these in because their centralized procurement team knows the sensor reliability is 94% uptime versus 87% on Sirona sensors of the same vintage.

Partially. Planmeca Intra talks RVG protocol, so Dentrix image module sees it fine, but Open Dental doesn't have native driver support - you'd need a third-party TWAIN wrapper like ImageWare or manual export, which is annoying. If you're locked into Open Dental, you're probably better off buying a Schick Elite or a Gendex GXS-700 instead.
Planmeca Intra runs 0.7–1.2 microsieverts per full-mouth series depending on tube voltage, which is about 60% lower than D-speed film and 40% lower than E-speed. Digital also kills the reshots - film forces you to nail technique, digital lets you adjust exposure in software, so your total annual dose per patient actually goes down 35–40% after the learning curve.
Dead pixels on CCD sensors are permanent - the cell's burned out and no software fix brings it back. One or two pixels in a corner usually don't impact diagnostics enough to warrant a $2,800 sensor replacement, but five or more or a cluster anywhere near the center means the image quality degrades enough that you'll get patient complaints about blurry teeth. I'd pass unless the price drops another $1,500.

Takes me 45 minutes to pull, test, package, and get documentation ready versus 3+ hours on a panoramic unit - inventory moves faster, less warehouse rent eating margins. A clinic that trades up clears $2,000–$3,500 per unit depending on their cost basis, so bundling three sensors with one pano keeps them happy and me paid.
