PurposeThe inferior alveolar neurovascular bundle (NVB) is important in implant placement and many other surgeries in dentistry because it is a major supplier of sensation and blood to the mandible via the mandibular canal. The purposes of the present study were to determine the areas and diameters of the NVB, the inferior alveolar nerve (IAN), and the inferior alveolar artery (IAA), and to. Bone resorption of the posterior mandible can result in diminished bone edge and, therefore, the installation of implants in these regions becomes a challenge, especially in the presence of the mandibular canal and its contents, the inferior alveolar nerve. Several treatment alternatives are suggested: the use of short implants, guided bone regeneration, appositional bone grafting, distraction. The incidence of inferior alveolar nerve disturbance after third molar removal has been reported to vary widely from 0.04 percent to 8.0 percent (Table 3) when using the typical buccal approach. Temporary disturbances, are by far more common, however; permanent problems have been reported in a frequency of 0.6 to 2.2 percent Table 1: Studies of the incidence of bifid mandibular canals. Many studies employed the use of cone beam computerized tomography (CBCT) and computed tomography (CT) scans. Some authors agreed that bifid mandibular foramina are observed more when using CBCT scans [13,14] and found it more accurate than multislice CT (MSCT) [].There is a possibility of the false presence of bifid mandibular.
