Avaliação das reformatações de arquivos DICOM, originados de tomografia computadorizada de feixe cônico, para planejamento cirúrgico virtual em implantodontia

Abstract

Methods of surgical planning based on images from cone beam computed tomography are used to improve therapy in Implantology. This technology allows the manipulation of images by the Dental Surgeon. For this, it is necessary that the image sent for clinical radiology has been resized / converted to a program of virtual surgical planning, necessary to make the examination compatible with the processing power of home computers. The aim of this study was to compare the sharpness and height measurement of coronal section of the mandibular posterior region in 55 CT scans between DICOM files reformatted in 3 (RF-3X) and 5 (RF-5X) times, and not reformatted (S-RF). The S-RF group showed sharper images than the RF-3X and 5X-RF groups. The variance analysis of the sources of variation inherent in the measurement process was statistically significant between groups (p ≤ 0.05). By Gage R & R study concluded that measures of height of coronal mandibular right and left, did not differ in groups S-RF, RF-3X and 5X-RF.
