There was no other tomographic alteration. There was no tomographic evidence of a MC bifurcation, no pathological process, and one exodontia 10 years ago. This IAN fenestration was a variation of the MC trajectory at the mandible buccal surface. This anatomical variation was not observed on the left side. #Invivo anatomage 5 download software#During the evaluation of tomographic images using i-CAT Vision software (Imaging Science International, Hatfield, PA), an atypical IAN fenestration in the buccal right surface of the mandible was observed near the third molar, with 4.5 mm of extension ( Fig. The scan was performed using an i-CAT Classic device t with 8 cm × 0.3 voxel size × 20 s of protocol scanning. Case reportĪ 45-year-old Caucasian female patient was referred for a CBCT exam in order to evaluate jaw bone conditions prior to dental implant placement surgery. 6 The aim of this case report is to illustrate one unusual CM with an atypical trajectory at the buccal mandible cortex through a cone beam computed tomography (CBCT) exam. It was related that 7% of the MC are in contact to mandible buccal cortex. 3–5 Even though textbooks do not provide a detailed description of the MC course, it has been reported that nerve and vascular bundles may be close to the buccal cortex. 1–3 Sometimes, the mandibular canal (MC) course is close to the roots of the teeth or to the lower border of the mandible, 4 and MC anatomical or trajectory variation has been described. 1 To avoid iatrogenic injuries to the IAN, the course, shape, curve, and direction of the mandibular canal must be considered, and damages may cause paresthesia and vessel injuries, bleeding, or hematoma.
