Table 3 Radiographic positioning
Projection | Description of the projections | Central beam |
|---|---|---|
Dorsoventral | Both mandibles positioned on the plate, hard palate parallel to the table, vertical beam | Cross point of midline and line between two MOCs* |
Laterolateral | Sagittal plane of the head parallel to the plate, horizontal beam | Half distance between ear base and lateral nostril angle on the facial crest |
Left to right lateral30°dorsal-lateroventral oblique | Imaging plate parallel to the sagittal plane of the head | Half distance between ear base and lateral nostril angle on the line parallel to nasal margin which goes through lateral nostril angle |
Left to right lateral30°ventral-laterodorsal oblique | Imaging plate parallel to the sagittal plane of the head | Half distance between ear base and lateral nostril angle on the rim of the corpus mandibulae |
Intraoral VD of lower jaw | Intraoral plate, vertical beam | In the midline at the caudal aspect of the symphysis mandibulae |
