CT multiplanar image anatomic study on orbital bone used for implant operation / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the orbital bone quantity by spiral computer tomography (CT) for orbital implant operation.</p><p><b>METHODS</b>Fifty-two normal skull specimens with marks received spiral CT scan and their multiplanar images were obtained. The quantity (length x width) were measured on multiplanar images.</p><p><b>RESULTS</b>The right orbital bone quantity at 7:00 was the highest, average 11.91 mm x 8.38 mm, and at 3:00 was the lowest, average 2.31 mm x 1.34 mm. The left orbital bone quantity at 5:00 was the highest, average 12.03 mm x 8.56 mm, and at 9:00 was the lowest, average 2.44 mm x 1.29 mm. There had no significance correlation with gender at the same position in both sides.</p><p><b>CONCLUSION</b>Useful data had been obtained for the selection of the placement sites, direction, length, and diameter of orbital implants.</p>
