Impression scan
A special Impression Scan program
produces very precise 3D images of
impressions and plaster casts.
• The first CBVT unit integrated 3D
surface scan
• CBVT volume and 3D photo in
one scan
• 3D photo acquisition can be
acquired separately
• Totally radiation-free process
• Lasers scan face geometry
• Digital cameras capture colour texture
• Software calculates information into a
3D photo
• No additional equipment required; all
components are integrated to sensor
housing

Images are taken with the same
flat panel 3D sensor
Work flow is the same as in 2D
imaging programs
• Same patient positioning
• Same image processing
parameters
Frames grabbed with slit beam
and narrow sensor area
Tomosynthesis applied to
calculate the panoramic images
• ~2000 frames, snap shots, are taken during the panoramic scan
• 9 different panoramic layers with 2 mm shift are calculated from the
frames
• +1 panoramic image in which the layer is optimised automatically
• 10 panoramic images are saved as a stack
• You can browse the images and select the best
Optimized SmartPan takes the panoramic image only from teeth area
• Reduces the patient dose
TMJ’s can be imagined separately
• Optimal imaging angle for TMJ’s
• Images are save in a study in Romexis

• Export 3D rendering surface in STL model directly
from
Romexis software
• STL export especially designed for Digital Cast

• Digital cephalostat is ideal for
cephalometry
• all information for orthodontic
planning
• lower radiation dose
• faster procedure
• 3D to be used for detailed e.g.
occlusion views, impacted
teeth etc. if needed
• Same Promax unit for both
studies
• Optimum for orthodontic
imaging
Flat panel
detector
• Planmeca ProMax 3D works with cone
beam computed tomography (CBCT)
principle.
• CBCT uses wide conical or pyramid
shaped x-ray beam instead of narrow
fan beam.
• The 3D image is one 3-dimensional
volume, not a pile of narrow slices.
• CBCT scan is only one rotation around
the patient. Medical CT needs several
rounds around the patient.
• CBCT:
• is faster
• has lower dose
• has better resolution

X-ray source
• Snap shot images taken with
synchronized X-ray pulses
• Stroboscopic effect for
maximum clarity of the images
• Accumulated X-ray exposure
time is 2.8 – 18 s – reduced
dose
• Proprietary 3D reconstruction
algorithm
• Voxel size 100, 200 or 400 µm
depending on resolution mode
and volume size
• Resolution up to 5 lp/mm
(Nyquist)
Symmetric scanning
• C-ram rotates
• Magnification 1.8x
• Scan angle 210°
• 300 - 500 frames
• Max. volume Ø70 x 70 mm
Asymmetric off-set scanning
• Elbow arm rotates
• Magnification 1.44x
• Scan angle 360 deg
• 450 - 600 frames
• Max. volume Ø160 x 90 mm
Sensor shift changes the
acquisition geometry and
reduces the final image quality
The shift of whole c-arm keeps
the acquisition geometry
constant and produces better
final image

CBCT has always an isotropic voxel
The reconstruction can produce any
size of voxel
The voxel is always perfect cube
The measurements are exact
Voxel size is typically 0.1 – 0.5 mm
CT has an anisotropic voxel
The voxel is always a “brick”
The pitch (= distance between spiral
rounds = layer thickness) varies and
causes distortion in the 3D
measurements.
The layer thickness is typically 0.5 –
0.8 mm
Pulsed X-ray produces sharp images with less dose.

panel imaging chain
X-ray Tube – Patient – Flat Panel - Digital Image
Conventional imaging chain
with Image Intensifier
X-ray Tube – Patient – Image Intensifier – TV
Camera – Digital Image
Modern Flat Panel Technology for maximum performance
•Image intensifier has both
distortion and brightness
non-uniformity which is
absent from the flat panel
detector
•Image intensifier needs
periodical maintenance. It
has limited life span 3-6
years.
•It is sensitive to magnetic or
electrical fields.
•It is over 60 years old
technology.
