-
下颌管在下颌骨内成弧线形贴近下颌骨下缘走行。
The mandibular canal appeared inside and was along the lower edge of the mandible in a curved shape .
-
结果:下颌管是下颌骨的骨松质内形成较薄的骨密质骨管。
Results : Mandibular canal was formed by a thin layer of compact bone in spongy bone of mandibular bone .

结果下颌管前端分出同一方向前行的切牙神经管和向后、上、外转弯的颏管。
Results The anterior end of the mandibular canal is divided into two canals : incisor never canal , which spreads forward in same direction .
-
②下颌管中心(M)到与M点在同一水平线的颊侧点(O)的距离;
The distance of Mandible of the Centre ( M ) and M points to the horizon at the same point of the buccal ( O );

目的研究国人切牙神经管的位置及下颌管、颏管的关系,为临床手术提供解剖学数据。
Objective To study the feature of the incisor nerve canal and its relation to the mandibular canal and mental canal so as to offer a reliable anatomical data for the distric operation .
-
下颌管内的下牙槽神经、血管被-层被膜包裹形成下牙槽神经血管束,下牙槽血管位于下牙槽神经的上方,且位置较恒定。
The inferior alveolar nerve and vessels were enclosed by the connective tissue to form a neurovascular bundle in the mandibular canal , and the inferior alveolar vessels were laid above the inferior alveolar nerve .
-
方法:磨开13例(26侧)甲醛溶液固定的湿下颌骨标本的下颌管前段、颏管和切牙神经管始段,直接观察测量。
Methods : The anterior parts of the mandibular canal , the mental canal and the origin of the incisor nerve canal were dissected and measured directly on 13 cases of Chinese wet mandible specimens fixed with formalin .
-
磨牙区下颌管与牙根尖距离从前向后逐渐减少,下颌神经管显现率从后向前逐渐降低,上下壁全部显现68%,下壁显现28%,不显现4%。
The distance between mandibular canal and root point at mandibular molar area decreased gradually from forth to back . The display ratio of both margins of mandibular canal was 68 % , only lower margin 28 % , none 4 % .
-
结果:下颌管前端向中线分出一切牙神经管后,该管有96.7%弯向后上形成颏管再开口于颏孔,3.3%直接开口于颏孔;
Results : The incisive nerve canal were apart from anterior ends of mandibular canals , and only 3.3 % of them ended directly in mental foramina , 96.7 % of them bended backward and upward forming mental canal and then ended in the mental foramina .
