Midmark® Preva Intraoral X-Ray System
Designing better care.
FLAWLESS IMAGING AND ENHANCED WORKFLOW
Preva packs many powerful features into one attractive, reliable system.
Detect dental caries and other problem areas with the razor-sharp images achieved through Midmark Preva Intraoral X-Ray systems. Preva systems are easy to operate and provide effortless movement for efficient workflows with one-handed, drift-free positioning. Designed to capture the images needed in just one shot, Preva units can help minimize patient stress.
Preva X-ray systems use a high-frequency direct current (DC) method of image capture in a range of models—Preva DC, Preva 2.0, and Preva Plus—and mounting options for your practice needs. The Preva 2.0 includes a high-speed USB connector for your digital sensors. The Preva Plus is integrated directly with the Midmark Intraoral Digital Sensor System and includes built-in sensor storage for convenience and sensor protection.
Use the Preva Intraoral X-Ray System to:
- Identify cavities and visualize tooth roots
- Examine the status of developing teeth
- Monitor the overall health of the bony area surrounding the tooth
[Image Description: A photograph shows a dental operatory with a Midmark Preva Intraoral X-Ray system mounted on an articulated arm positioned above a dental chair. The system features a sleek, modern design. Two inset images show diagnostic X-ray views of teeth (labeled 01) and a dental professional interacting with the X-ray unit (labeled 02).]
FEATURES
- The Preva system is designed for effortless movement and fast one-handed positioning.
- Auto-calibration between every capture ensures consistent image quality.
- The proprietary dual-arm braking system helps the head stay exactly where you position it without sagging or drifting.
- Preva provides a 0.4 mm focal spot for sharp, well-defined details that allow easy identification of pathology with both film and digital sensors.
- The easy-to-use LCD control panel with large icons helps to identify target tooth, receptor type, and patient size while offering pre-programmed technique settings.
- All Preva models are available in multiple mounting configurations to best suit your operatory needs: wall, cabinet, or mobile.
- The Preva Plus is configured with the additional integration of the Midmark Intraoral Digital Sensor System and built-in storage to help keep sensors from being damaged or misplaced.
- Preva units are designed and packaged for fast and easy installation.
