Planmeca ProMax tomography

Planmeca ProMax tomographyFour tomography modes

•Wide beam linear tomography (film)

•Wide beam true linear tomography (film)

•Digital linear tomography•Digital Transtomography™

Film tomography

Wide beam linear tomography

• Cassette is perpendicular to the X-ray beam

Wide beam true linear tomography

• Cassette is kept parallel to the image layerConstant resolution over the whole

exposed area

Linear vs true linear tomoraphy

pin phantom

Linear:

• The thickness of the layer is not regular

True linear:

• The thickness of the layer is regular

Linear vs true linear tomoraphy

Tomography

Linear:

• The resolution is optimum only in the middle of the image

True linear:

• The resolution is constant all over the image

Digital tomography

Digital Transtomography™

Multiple sweep - the beam makes oscillating and transitional movement

Straight layers, adjustable thickness

Better layer separation

Digital linear tomography One sweep - the rotating point moves

along the layer during imaging Straight 6mm layer Fast

Tomography features• Straight cuttings• Layer thickness selectable (1, 3, 6,

9, 18, 36 mm)• Adjustable step between layers• Constant 1.50x magnification• Pre-programmed cutting sites

(based on jaw size)• Pre-programmed cutting angles

(based on jaw shape)• Automatic or manual operationsSpecialised imaging at the dental

practice High value for implantology

Cross-sectional tomograms• 1-4 cross-sectional images (manual)• 4 cross sectional images (automatic)• 3 cross sectional images with different angles (automatic)• 4 cross-sectional with anatomical angles• 3 cross sectional images from sinus and nasal cavity (automatic)

Tomography programs

Longitudinal tomograms•1-4 longitudinal images (manual)•3 longitudinal images (automatic)•3 longitudinal images with different angles (automatic)•3 longitudinal images from the sinus and nasal cavity

transtomogram

Tomography programs

Mixed tomograms• 1 cross-sectional and 1 longitudinal

images (automatic)• 3 cross-sectional images and 1

longitudinal image (automatic)• 3 cross-sectional images with

different angles and 1 longitudinal image (automatic)•Mixed tomograms give 3D-

information from the target site• Necessary for exact

measurementstranstomogram

Step #4 Make program selections

Taking tomogram

• ProMax's concept positions the patient automatically so the area to be exposured is precisely within the focal layer.• The operator simply selects the

proper coordinates of the object, and ProMax goes to the right position.

Taking tomogram

Step #5 Set layer to mark with joystick Adjust angle with the angle buttons

Taking tomogramStep # 6 Patient in machine

Fine adjust the target with the positioning lights

Patient bites the impression When the target is upper jaw, adjust the maxillary alveolar ridge horizontal

When the target is lower jaw adjust the lower part of the mandible horizontal

Taking tomogram

Step # 7 touch Ready Step # 8 Press exposure button

3 x CRS 1xLNG Auto Angle

Taking tomogram

The diagnostic set must include the longitudinal and the one best cross-sectional images.
