For historical reasons, most sensors place necessary electronics near the edge where the cord exits the sensor. The result is a dead space of up to 6mm, since the electronics cannot also be part of a sensor’s active imaging area. So, for bitewing purposes, the very edge used to capture the canine/premolar contact may not capture any image at all for its first 3-6mm. Clinicians who regularly place sensors instantly see this as a problem.

By moving the electronics elsewhere, XDR engineers achieved a 2mm mesial dead space, little more than the dead space common with film packets. Doctors report that good parallel technique is easier to achieve with XDR’s Anatomic sensor. The maximized mesial imaging area aids capture of the canine/premolar contact. And that bitewing images more often display 8 contacts for diagnosis

The Anatomic Sensor also achieves a practical standard of spatial resolution in dental radiography. With that, the ability to see anatomic structures is enhanced, improving diagnosis.
