3. Close Gate, making sure the magnet is secured in its locked
position.
4. Use the Patient ALIGN buttons on the
Alignment Control Panel to adjust the Patient
Chair height. These controls allow movement of
the Patient chair, up (
Δ
) and down (
∇
), to
facilitate Patient alignment with the Chin Rest.
When properly aligned, the Patient’s chin is able
to sit on the Chin Cup at the appropriate tilt (see
illustration below).
5. Ensure the tilt of the Patient is such that the
Occlusal Plane is Flat, which means Frankfurt
Horizontal is tilted up by about 5 degrees (see
illustration below).
WARNING
Laser beams can cause optical damage. Do not stare
into the laser beam. Instruct the Patient to avoid
looking into the beam. The use of optical instruments
such as eyeglasses with large diopter or mirrors,
increase eye hazard with this product.
6. Alignment Light: In general, the Alignment
Light shall be positioned at the horizontal
Occlusal Plane.
•
Full Head Scan: The Horizontal light should be at the
Occlusal Plane between the lips (smile line).
•
Clearance: Make sure that the sensor side of the turret has
enough clearance as to NOT brush the Patient’s shoulders
as it rotates. This may cause movement.
CAUTION CAUTION
The horizontal Alignment Light may vary slightly depending on the
Patient position according to the selected height of scan desired,
refer to taking a Preview, in the next paragraph, to ensure that the
target area of interest is in the image.
