Summary:To fabricate a rapid prototyping (RP) 3-D image models for individual reconstruction of orbital bony loss. The skull was placed on a helical CT scanner table and the Frankfort plane was perpendicular to the table. The CT data was obtained by a Aquilion (TOSHIBA, Japan) with 1 mm thickness section in spiral mode. By adjusting of CT threshold value and pixels in order to stack the segmental defects, we obtained an approximate 3-dimension visual model of the scanned skull using MedGraphics software. An orbital RP model based on the dataset of the 3-dimension visual model was fabricated by RP machine. Both 3-dimension visual model and RP model were measured against the skull with several anatomic landmarks to examine the accuracy of the models, and the errors were analysed. Integrity precision rapid RP models of the orbital region were reconstructed. The anterior orbital rim, middle orbital section and posterior orbital section were all fabricated.
