| Abstract: | BACKGROUND To study the clinical value of multiplannar reformation,curved plane reconstruction and shaded volume rendering technology of spiral CT in locating impacted teeth. CASE REPORTS Forty multiple impacted teeth of 22 cases were examined with spiral CT. All cases received multiplannar reformation,curved plane reconstruction and shaded volume rendering. The reconstruction image could clearly display the shape,location and eruption orientation of the impacted teeth. DISCUSSION He post processing original image technique by MSCT can provide valuable diagnostic and anatomic information of the impacted teeth. |
