Intended Use

The Orthoralix 8500 Panoramic Dental X-ray System is to be used as an extraoral source of x-rays for imaging of the dento-maxillo-facial area.

Device Story

The Orthoralix 8500 is a rotational panoramic dental X-ray system. It consists of a wall-mounted column, a motor-driven overhead assembly, an X-ray tubehead with DC power supply, and a cassette drive system for 15 x 30 cm film. During operation, the tubehead and cassette holder rotate around the patient's head; the X-ray beam is collimated by a slit diaphragm. Patient positioning is facilitated by three lasers, a bite guide, and head stabilizers. The system features a standard panoramic mode and a child-specific mode to reduce radiation dosage. Movements are microprocessor-controlled. The device is intended for use by dental professionals to produce radiographic images for clinical diagnosis of the dento-maxillo-facial area.

Clinical Evidence
