Abstract

Abstract

Objective Cone-beam computed tomography（CBCT）was used to observe the anatomical structure of the mandibular canal in the mandible, providing theoretical basis for dental implants and alveolar surgery. Methods According to the inclusion and exclusion criteria, a total of 339 cases of CBCT imaging data were collected; all the cases were divided into groups on the basis of age and gender; and the anatomy and position of the mandibular canal was measured and analyzed. Results The lengths from mandibular canal to alveolar ridge crest, buccal bone plate, the lingual bone plate and the root apex were statistically significant among the different age and gender groups（P < 0.05）; the lengths from mandibular canal and the inferior margin of the mandible was statistically significant among age groups（P < 0.05）, but there was no statistical significance in gender groups（P > 0.05）. Conclusion The location of the mandibular canal are highly variable. The mandibular canal runs in the mandible from the distal to the medial, from the tongue to the buccal side and gradually approaches the alveolar crest. The use of CBCT can clearly demonstrate the three-dimensional location of the mandibular canal in the mandible, which has great clinical guidance and reference value for the mandibular surgery and implant surgery.
