Image Receptor Holding Device Helps Make Distortion-Free Image

The paralleling technique is the most accurate technique for taking periapical and bitewing radiographs. Devices used to accomplish this include receptor instruments with ring guides, standard biteblocks, bitewing tabs, and image receptor holders that hold the image receptor stable during handling.   Image Receptor Holding Device: The purpose of the image receptor holding device is to aim the x-ray beam perpendicular to the teeth and the image receptor (positioned parallel to the teeth) to obtain a distortion-free image. Especially with bitewings, even slight overlapping of the interproximal surfaces on the image may lead to misdiagnosis. If the holding device was properly aligned and yet overlapping still occurs in the image, it is because of anatomical reasons or teeth being ectopically positioned. There is no solution for this. As always, clinical and radiographic examination together will provide you of the right diagnosis.  Image Holders: Disposable Styrofoam image hol more...
