The CS 8100 3D uses dental 3D technology to limit radiation dose and ensure safer exams.

  • Confine radiation to area of interest with flexible fields of view.
  • Control size, resolution, and dose for each exam.
  • Adherence to the ALARA Principle helps you keep radiation exposure as low as reasonably achievable.
  • Dental 3D technology reduces exposure significantly more than conventional CT systems.

The CS 8100 3D is designed for accuracy, with a high-frequency X-ray generator, 4T CMOS sensor, and vibration-free motion system working together to ensure smooth image capture.


  • Delivers sharp, contrasted images with resolution up to 75 μm
  • 3D images offer more accurate views of patients’ dental anatomies
  • View the area of interest from every angle, with one-to-one accuracy
  • 3D images eliminates overlap and distortion


Dual jaw mode (8 cm x 9 cm)*—capture both dental arches in a single scan for cases that involve a larger area

  • Single jaw mode (8 cm x 5 cm)—ideal for cases that require a full view of either mandible or maxilla, including implant planning with surgical guide creation and oral surgeries.
  • Universal field of view (5 cm x 5 cm)—the ideal compromise of image size and dose, this mode ensures you receive the details you need, with no unnecessary information; ideal for most local dental applications.
  • EndoHD mode (5 cm x 5 cm; 75 µm resolution)—high-resolution mode delivers maximum precision for exams that require greater visibility of the patient’s root and/or canal morphologies; best-suited for endodontic applications.
  • Pediatric program (4 cm x 4 cm)—limit patient exposure by confining radiation to a small area; a great option for younger patients, implant planning, and follow-up exams.


Whether you are the user or the patient, the CS 8100 3D makes image acquisition quick and simple.

  • Intuitive interface and letter landmarks on the bite block simplify the examination process.
  • Open, face-to-face design puts patients at ease and promotes comfort.
  • Fast scanning times (7 seconds minimum) prevent movement and reduce retakes.
  • Accessible to patients of all sizes and individuals in wheelchairs.
