Materials & Methods: 102 subjects in age ranged 18- 40 years of age underwent CBCT imaging (i-CAT) performed with voxel size of 0.3 mm and exposure cycle of 8.5 seconds. The available height of the potential implant site is determined by the distance between the alveolar crest of ridge and the superior cortical bone of the MC.1 The interforaminal region is usually known as the safest area for dental implant surgery. [...]panoramic radiographs are used as the single preoperative diagnostic or radiographic tool for implant planning.2 However, panoramic radiographs have some disadvantages: the magnification in the anterior region is small on panoramic radiographs, there are often distortions and magnifications of the anatomical structures, which result in either over- or underestimation of the real size of the anatomical structures.3 Several imaging modalities have been used to assess the course of the MC, including panoramic radiography, conventional tomopraphy, CT, intraoral periapical films and CBCT.4 Panoramic radiography lacks accuracy and reliability with regards to calculations of distances made using them. The clarity of conventional tomography has increased as a result of the increasingly complex, synchronized, poly-directional movement patterns during imaging.6 The present study was conducted to assess mandibular canal visibility in CBCT images. Discussion In the past, computer tomography (CT) with special dental software programs was used to determine the anatomical structures for dental implant planning, and it has been recognized as a useful imaging device.7,8 Today, cone beam CT (CBCT), as a three-dimensional dental diagnostic tool, provides reliable data for correct distance measurements and can be used to obtain detailed information for three-dimensional analysis of the region of interest.9 Currently, the use of CBCT imaging is increasing, especially in dental implant planning as a result of low cost, fast image acquisition and lower exposure dose compared to CT.10The present study was conducted to assess mandibular canal visibility in CBCT images.
