DIAGNOSTIC Guide 3 mm post & sleeve 4 mm post & sleeve 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 distalaccomplished 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
#12 GALAXIS 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 tangential view cross sectional view Both views indicate #12 to be well aligned no need to be corrected
GALAXIS # 13 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. Cosine is applied to determine correction data. * see next 4 slides
DéPlaque 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 .

GALAXIS # 14 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.
# 19 GALAXIS tangential view cross sectional viewANGULAR CORRECTION of 6.6 to the lingual will be neededand 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.
