Performance, size and quality are obviously key, but make sure to also patient discomfort that can be cause by the rigid edges of x-ray film packets. 20 years ago a RDH invented Edge-Ease®, the original dental imaging comfort cushion. By wrapping the edge of the film with Edge-Ease, the patient’s soft tissue was protected from abrasions and discomfort. This, in turn, enabled the patient to bite harder for more precise positioning and a more accurate x-ray, with less need for retakes. So consider rough seams vs smooth seams of digital sensor sleeves and hard vs smooth edges to maximize patient comfort.
