Comparison of Image reformation Using Personal Computer with Dentascan Program

• Kim EK

Abstract

This study was performed to demonstrate the method of image reformation of dental implants, using a personal computer with inexpensive softwares and to compare the images reformatted using the above method with those using Dentascan s oftware. CT axial slices of 5 mandibles of 5 volunteers from GE Highspeed Advantage(GE Medical systems, U.S.A.) were use d, Personal computer used for image reformation was PowerWave 604/120(Power Computing Co, U.S.A.) and softwares used were Osiris(Univ. Hospital Of Geneva, Switzerland) and ImportACCESS V1.1(Designed Access Co., U.S.A.) for importing CT imag e and NIH Image 1.58(NIH, U.S.A.) for image processing. Seven images were selected among the serial reconstructed cross- sectional images produced by Dentascan(DS group). Seven resliced cross-sectional images at the same position were obatai ned at the personal computer(PC group). Regression analysis of the measurements of PC group was done against those of DS group. Measurements of the bone height and width at the reformed cross-sectional imges using Mac-compatible computer we re highly correlated with those using wokstation with Dentascan software(height: r2=0.999, p<0.001, width: r2=0.991, p<0.001). So, it is considered that we can use a personal computer with inexpensive softwares ofr the dental implant planning, instead of the expensive software and workstation.
