CLINICAL MEDICINE

Detailed explanation-1: -Maxillary region: For bisecting angle radiographic images of the maxilla, the patient should be positioned so that the maxillary occlusal plane is parallel to the floor and the sagittal plane of the patient’s head is perpendicular to the floor.

Detailed explanation-2: -The patient’s head needs to be positioned so the chin is parallel to the floor. The PID usually has a line on the side. That line should line up with the occlusal plane. For bitewing radiographs, maxillary and mandibular arches should show an equal amount from the occlusal plane.

Detailed explanation-3: -How is the patient’s head positioned before exposing a maxillary occlusal receptor? parallel to the floor and the midsagittal (midline) plane perpendicular to the floor.

Detailed explanation-4: -With the paralleling technique the image receptor is positioned near the center of the oral cavity, where it must be retained in a position parallel to the long axes of the teeth.

Detailed explanation-5: -Basic principles of occlusal technique: 1. The receptor is placed with the tube side facing the arch that is being exposed. When using film, it is positioned with the white side facing the arch that is being exposed.
