1. Planmeca ProMax tomography

2. Planmeca ProMax tomography
Four tomography modes
Wide beam linear tomography (film)‏
Wide beam true linear tomography (film)‏
Digital linear tomography
Digital Transtomography™

3. 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 layer
Constant resolution over the whole exposed area

4. 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

5. Linear vs true linear tomoraphy
The resolution is optimum only in the middle of the image
True linear:
The resolution is constant all over the image
Tomography

6. Digital tomography Digital linear tomography
One sweep - the rotating point moves along the layer during imaging
Straight 6mm layer
Fast
Digital Transtomography™
Multiple sweep - the beam makes oscillating and transitional movement
Straight layers, adjustable thickness
Better layer separation

7. 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 operations
Specialised imaging at the dental practice
High value for implantology

8. Tomography programs
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)‏
The interval between cuttings is selectable by the user (1, 3, 6, 9 or 12 mm)‏
Angle between cuttings in multi- angle tomograms is ±6°, the image no 2 corresponds to the selected target position
Anatomical angles are according to the curvature of the jaw, the image no 2 corresponds to the selected target position

9. 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
angle between cuttings in multi- angle tomograms is
transtomogram

10. 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 measurements
the interval between cuttings is selectable by the user
angle between cuttings in multi- angle tomograms is
transtomogram

11. Taking tomogram Step #1 Take impression Step #2 Mark the target
Step #3 Impression in machine
Step #4 Make program selections
Step #5 Set layer to mark
Step #6 Patient in machine
Step #7 Touch Ready
Step #8 Exposure

12. Taking tomogram
Step #1 Take Impression

13. Taking tomogram
Step #1 Take impression
Step #2 Mark the target

14. Taking tomogram
Step #3 Impression in machine

15. Taking tomogram
Step #4 Make program selections

16. 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.

17. Taking tomogram Step #5 Set layer to mark with joystick
Adjust angle with the angle buttons

18. Taking tomogram Step # 6 Patient in machine
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
Fine adjust the target with the positioning lights

19. Taking tomogram
Step # 7 touch Ready
Step # 8 Press exposure button

20. Taking tomogram 3 x CRS 1xLNG Auto Angle
The diagnostic set must include the longitudinal and the one best cross-sectional images.
