Computed tomography (CT) has been shown to be useful tool for the preoperative evaluation of the maxilla and maxilla mandible for dental implant treatment. It is also excellent in evaluating postimplant periimplantitis. Panoramic radiographs have been used for both dental implant treatments and prediction of low bone mineral density in patients. The stability of dental implants during placement depends on the condition of the bone and is of-ten difficult to achieve the stability, with low

In osteoporosis, it is well understood that the mandibular cortical bone undergoes resorptive activity, leading to declined thickness and more porous inferior border, characteristics that can be determined by panoramic radiographs (1) . Indicators such as mandibular cortex index (MCI) and mandibular cortical width (MCW) are used to quantitatively evaluate the quality of mandibular mass. MCW is the average width of the mandibular cortical bone below the two mental foramina. It has been reported that the index of the mandible obtained in a CT image is comparable to that obtained in panoramic images, indicating an efficient use of the index in CT images Correspondence to:
