(Bite-Wing Technique Errors) Receptor Placement Problems Flashcards
What does a correct receptor placement image show?
Crowns of both maxillary and mandibular teeth, the interproximal contact areas, and crestal bone.
(Correct) Premolar Bite-Wing
Must be positioned such that the resulting image shows both maxillary and mandibular premolars and the distal contact areas of both canines.
(Correct) Molar Bite-Wing
Must be positioned such that the resulting image shows both maxillary and mandibular molars. Th molar bite-wing must be centered over the mandibular second molar.
What does an Incorrect receptor placement image show?
Result in absence of specific teeth or tooth surfaces on an image, a tipped occlusal plane, overlapped interproximal contacts, or a distorted image.
(Incorrect) premolar Bite-Wing
Appearance: The distal surfaces of canines are not visible.
Cause: The bitewing receptor was positioned too far posteriorly in the mouth.
Correction: Make certain that the anterior edge of the bite-wing receptor is positioned at the midline of the mandibular canine.
(Incorrect) Molar Bite-Wing
Appearance: The third molar regions are not visible on the image
Cause: The bite-wing receptor was positioned too far anteriorly in the mouth
Correction: Make certain that the anterior edge of the bite-wing receptor is positioned at the midline of the mandibular second premolar. ALWAYS center the molar bite-wing on the mandibular second molar.
