This study was performed to demonstrate the method of image reformation for dental implants, using a persona) computer with inexpensive softwares and to compare the images reformatted using the above method with those using Dentascan software. CT axial slices of 4 mandibles of 4 volunteers from GE Highspeed Advantage(GE Medical systems, U.SA) were used. Personal computer used for image reformation was PowerWave 604/120 (Power Computing Co, USA) and softwares used were Osiris (Univ. Hospital of Geneva, Switzerland) and ImportACCESS VI.1(Designed Access Co., USA) for importing CT images and NH Image 1.58 (NIH,U.SA) for image processing, Seven images were selected among the serial reconstructed cross-sectional .images produced by Dentascan. Seven resliced cross-sectional irrj?ges at the- same position were obtained:at the personal computer.
Regression analysis of the measurements of PC group was done against those of DS group. Measurements of
bone height and width at the reformed doss-sectional images using Mac-compatible computer was highly anrti~ ~~ with. those using workstation with Dentascan software(height : r2= 0.999, p<0.001, width : r2= 0.993, p <0.001). So. it is considered that we can use a personal computer with inexpensive software for the dental implant plum instead of the expensive software and workstation.
