Incorrect Horizontal Angulation: positioning the central ray so that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth, provides an image that has overlap of adjacent structures in the horizontal plane (the contact areas of the teeth are superimposed over each other). Both storage phosphor (SP) plates and charge-coupled devices (CCDs) must be wrapped in a protective sleeve before being placed in the patients mouth, and CCDs require a sensor holder.
