用杂交成犬30头观察了牙周膜血管和牙槽骨的关系:(1)分布在牙周膜的血管有3个径路:①从牙龈越过牙槽顶部进入牙周膜的血管;②贯穿牙槽壁向牙周膜分支的血管;③在根尖部进入牙髓的血管分支出起分布到牙周膜,(2)分布在牙周膜的血管网有两层结构:牙槽骨侧为粗的血管网,牙根侧为细血管及毛细管。从牙根侧的血管网派生出各种形态的圈,(3)有450～40μ大小不等的福耳克曼氏管(骨膜下层容纳血管的小管——译者注)在牙槽骨内开口,其中有静、动脉出入,(4)在槽间隔、根间隔可见到大
The relationship between the periodontal ligament and the alveolar bone was observed by hybridization of 30 dogs: (1) There were three pathways in the blood vessels distributed in the periodontal ligament: (1) the blood vessels that entered the periodontal ligament from the gums over the top of the alveolus; (2) The wall of the alveolar wall branches to the periodontal ligament; (3) the blood vessel branches into the periodontal membrane distribute to the periodontal ligament; (2) the vascular network distributed in the periodontal ligament has two layers: the alveolar side For the coarse vascular network, the root side of the small blood vessels and capillaries. Derived from the root side of the vascular network of various forms of the ring, (3) 450 ~ 40μ in size Fuerke Man tube (subperiosteal vascular tube transposable Note) in the alveolar bone opening, Among them, static, arterial access, (4) in the slot interval, the root interval can be seen large
