Fabrication of DIAGNOSTIC guide
Holes are drilled in the cast in the planned positions of the bicuspids and first molar.
Two 3 mm guide posts and a 4 mm guide post were placed in the holes in the cast.
Three ceramic guide sleeves were used to make the initial DIAGNOSTIC guide.

PREview of Pre-op Corrections
# 12
NO CORRECTION
#13
LINEAR CORRECTION
2.1 mm toward the bucal + 2.1 mm toward the distal
accomplished by: 3 mm offset guide post rotated 45° disto-buccally
# 19
LINEAR CORRECTION
2 mm toward the buccal
ANGULAR CORRECTION
6.6° toward the lingual
#14
LINEAR CORRECTION
3 mm toward the palatal
PRE-OPERATIVE Evaluation
GALAXIS Cone Beam Images
A cone beam X-ray was taken and the images are viewed for each individual site
to verify or correct the position of the guide sleeve.
Panoramic views in the GALAXIS (Sirona) software are not very accurate.
Therefore, tangential & cross sectional views are used to verify the sites in next slides.
GALAXIS
#12
tangential view
cross sectional view
GALAXIS
Both views indicate #12 to be well aligned
no need to be corrected
# 13 panoramic view
middle implant highlighted in orange
GALAXIS
tangential view cross sectional view
Both views indicate the 3 mm ceramic guide sleeve should be moved to the buccal &
distal to correct the position of the proposed osteotomy.
This means: a LINEAR CORRECTION of 2.1 mm bucally and 2.1 mm distally
made by using a 3 mm offset guide post rotated 45° disto-buccally. The angle of the guide sleeve is correct. Therefore , NO ANGULAR CORRECTION.
GALAXIS # 13
Cosine is applied to determine correction data.

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°.

GALAXIS
A 5 X 9 mm virtual implant is placed on the cone beam image and indicates
LINEAR CORRECTION: the guide post will need to be moved 3 mm palatally
by using a 3 mm offset post with no change in the angle of the guide post.

ANGULAR CORRECTION of 6.6° to the lingual will be needed
and a LINEAR CORRECTION of the guide post >
2 mm to the buccal using a 2 mm offset guide post to avoid perforation of the lingual plate.
The green line indicates the acceptable angle of the guide sleeve in the bucco-lingual plane.
