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

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

facial 1.06 mm

A= cosine of 45º X 1.5

(0.707 X 1.5 mm = 1.06 mm

guide post center

A= cosine of 45º X 1.5

(0.707 X 1.5 mm = 1.06 mm
