Abstract:
A simulation method for visualizing the density of a jawbone at an implant area into which an implant screw for supporting an artificial tooth is inserted, comprising the steps of:(a) forming a three-dimensional image of the jawbone, the image including information about the jawbone density;(b) setting a color map corresponding to the density distribution of the jawbone image;(c) modeling a virtual implant screw on a plurality of brick elements;(d) graphically inserting the virtual implant screw into a surgical area of the jawbone image;(e) calculating values of the jawbone density at the points where each brick element of the virtual implant screw abuts the jawbone image; and(f) searching for colors in the color map corresponding to the density values of the jawbone image at points adjacent to each brick element, and coloring faces of the virtual implant screw with said colors.
