If a negative vertical angulation is used, the occlusal surfaces of maxillary the molar bitewing image should be centered over the second molar for the patient with a hypersensitive gag reflux, the teeth that should be exposed last are maxillary molars the number of x-ray views that makes a patient's full-mouth series depends on ALL OF THE ABOVE or mandibular CANINE exposure-, Entire If you continue to use this site we will assume that you are happy with it. It is challenging to apply the work proposed for bitewing images directly to panoramic images because they are structurally different. The sensor or film will be placed parallel to the table between the maxillary and mandibular premolars.
