Abstract
We applied the image processing system by Macintosh Ⅱ computer to determination of implantation's prognosis on radiographs.And we were content with the results.Our systems were,Hard/Macintosh Ⅱ ci,RAM 8 MB,Hard disk 8 OMB (Apple), Removable hard disk 44 MB (SyQuest SQ-44). 13” color RGB moniter(Apple), Color video board(Raster Ops 24 STV), Scanner board(Barneyscan), 8 mm CCD(Sony), GT 6000 (Epson),Quick Scan(Barneyscan)Soft/Ultimagel.41 JP (graftek, IMI), Image 1.31(NIH, PDS), Media Grabber(Raster Ops), Color Magican Ⅲ (Three's), Photoshop(Adobe), Quick Scan V.2.1(Barneyscan), Excel 2.2(Microsoft), etc.
We experimented on one implant recovery case of 6, 7 removed 2 root type implants that were filled HAP past(6:A hole) and covered by Gore-tex film. After 3 months, we remorved the Gore-tex film. We took 9 X-P dental films, from the just after the operation until the reoperation day. We took image processing (about 9 original pictures) with our system. Those image processing experimental results correlated well with the real view when we conformed to diagnosed A and B holes at the reoperation time, A hole was healing and B hole was not healing.
Those results were very accurate.
