12.5 Ortho Rad dentition
The ortho rad panoramic exam delivers an image of the pure dental
arch, excluding the ascending rami branches of the temporo-mandibular
joint from the image; the trajectory of the rotating arms is, however,
optimised for a better orthogonality between the X-ray beam and
incident sections of near teeth. Thus the image has reduced teeth
overlapping, improving the diagnosis of interproximal decay.
As a consequence of the different trajectory, the focus layer, mainly in
the front teeth area, is smaller and patient positioning for this exam
needs more care. Follow the instructions for normal panoramic exams
for patient positioning.
12.6 Single Phase Bitewing (L/R)
The bitewing mode, right or left, means that only the corresponding bite
sector is irradiated; the emission will start from the beginning, to just after
the mid sagittal plane for the right part. For the left, it will start just before
the mid sagittal plane and continue until the end of the rotation. The
exam is performed with the same trajectory of the standard panoramic
exam, reducing the rays' emission time.
This exam is normally when it is already known that the patient has a
problem on one side of the bite-sectors of the arch, so it is possible to
reduce patient irradiation.
Follow the instructions for normal panoramic for patient positioning.
12.7 Bilateral Bitewing
The bilateral Bitewing mode, right and left, means that the two bite-
sectors are irradiated; the exam is performed with the same trajectory of
the standard panoramic exam, reducing the rays' emission time.
This exam is normally used when it is already known that the patient has
a problem on the bite-sectors of the arch, so it is possible to reduce
patient irradiation.
Follow the instructions for normal panoramic for patient positioning.
