Mid America Dental Sales, Inc. (MADS) has announced the release of the DC Air4, the fourth generation of its wireless Direct Conversion intraoral x-ray sensor. Previously distributed through factory-direct channels, the device is now being made available to a wider segment of the dental market via select authorized distributors.
The DC Air4 employs Direct Conversion (DC) technology, in which X-ray photons are converted directly into electronic signals without the use of scintillators or fiber optic plates. This design approach is intended to support higher-definition radiographs, enhanced visualization of fine anatomical detail, reduced image noise, and greater consistency in diagnostic image quality.
The DC Air4 is designed as a fully wireless intraoral sensor, eliminating the cable commonly associated with traditional systems. This removes a typical point of mechanical failure and may reduce operatory clutter. Key physical specifications include: weight = 13 grams; thickness = 5.2 mm, form factor = size #2. The absence of a cable may also facilitate sensor positioning and reduce intraoral bulk during imaging procedures.
Connectivity and Power Management
The system incorporates Bluetooth communication and an expanded battery capacity, supporting:
up to 10 hours of continuous operation
more than 250 exposures per charge
automatic pairing with compatible docking stations
integration with smartphone-based locator applications for tracking misplaced sensors
A custom locator application, currently in development, is expected to allow practices to set alerts if a sensor is not returned to its charger within a defined timeframe and to identify its location.
Ongoing Development of the DC Air Platform
Previous iterations of the DC Air platform have received recognition in clinical and laboratory evaluations for image quality and overall performance. The DC Air4 represents a continuation of this development, with updates to durability, ergonomics, and wireless functionality. The fourth-generation model can be visually identified by a gold cover over the sensor battery.
