To study the intramandibular course and anatomic structure of mandibular canal.
The intramandibular course of mandibular canal and its dimension were measured in 15 adults mandibles with teeth; the relationship between blood vessel and nerve was observed in 4 fresh samples in which the artery was filled.
The mandibular canal was close to the lingual side and the inferior margin of the mandible. The blood vessel lay above nerve in the mandibular canal.
In implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided. Hemorrhage is the earliest manifestation suggesting that continuing drill may damage the inferior alveolar nerve.
研究下颌管在下颌骨内的走行及解剖结构。
对15具带牙的成人下颌骨测量下颌管在下颌骨内的走行及其尺寸；在4例动脉灌注的新鲜标本上观察血管与神经的关系。
下颌管靠近下颌骨舌侧及下缘，下颌管内血管位于神经上方。
按正常解剖进行种植手术可避免损伤下牙槽神经。出血是最早的表现，提示持续钻磨可能损伤下牙槽神经。
