Comparison between conventional tomography & radiovisiography methods for assessment of presurgical dental implants

Statement of Problem: Computed tomography (CT) has proved to be the most precise method to evaluate the quantity of jaw bones.In recent years, patient dose which is much more greater in CT than conventional methods has attracted more attention, and has brought the idea of using the conventional method in more accurate ways or applying new methods with lower doses.radiovisiography for presurgical evaluation of endosseous implants. measured with the two aforementioned techniques. To determine the magnification factor, an acrylic stent with spherical lead markers with known diameter, has been used. Then in intra-operative phase, this distance was measured directly on the patient’s jawbone. To assess the significance of differences from radiography results and the gold standard the binomial distribution was used.significant and there was no significant difference between RVG and visual method.to conventional tomography. Radiography is the main tool for presurgical assessment of endosseous implants.The goal of this study was the assessment of the accuracy of conventional tomography andDistance between alveolar margin and superior border of mental foramen wasFindings showed that the differences between conventional omography and visual methods wereThis study revealed that the radiovisiography method showed more precise results in comparison.
