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

#9LINEAR 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 TheoremCOSINE 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
