Midmark Preva Intraoral X-ray System
High-Frequency DC X-ray Unit for Dental Imaging
Introduction
The Midmark Preva Intraoral DC X-ray System is designed to enhance dental practices by integrating superior technology into a common X-ray unit. It aids practitioners in identifying cavities, visualizing tooth roots, examining developing teeth, and monitoring the overall health of the bony area surrounding teeth.
PREVA – Flawless Imaging and Enhanced Workflow
The Preva system is a reliable imaging workhorse for dental offices, detecting cavities and other problem areas with exceptional image quality and proven mechanics. It offers effortless movement, drift-free positioning, and minimizes patient stress by capturing necessary images efficiently. Midmark Preva intraoral X-ray systems utilize a high-frequency direct current (DC) method for image capture.
For advanced convenience, the Preva Plus integrates with the ClearVision® digital sensor, enabling captured images to be viewed with Progeny® Imaging Software or other popular practice management programs.
