Yellow line passing through the axis of the implant creates the
view seen in the cross sectional view (next slide).
Greater accuracy in implant placement is achieved when the line representing
the bucco-lingual plane is set at 90° to the buccal surface of the arch.
Dragging the yellow line in the software will
change the cross sectional view as the line
rotates about the axis of the implant.

Review of Pre-op Corrections
#9
LINEAR CORRECTION
Cosine is applied to determine correction data.
* see next 3 slide
1.5 mm offset guide post rotated 45º toward the mesial & facial.
Pythagorean Theorem COSINE Calculations for Guide Right™ Guides
The cosine of 45°
is recommended for Guide Right corrections
BECAUSE
rotating the offset guide post half way
between 2 adjacent planes (90° apart) is 45°.
Correction based on the calculations
from the Pythagorean Theorem
To move the position of the guide sleeve 1 mm both mesially & buccally:
► use a 1.5 mm offset guide post
► and rotate the offset guide post 45º to a mesio-buccal position.
Cosine of 45° X 1.5 mm = 0.71 X 1.5 mm = 1.06 mm
