牙周膜胶原基质以夏贝氏纤维支抗于骨中的方式来附着于齿槽骨的沉积面早已明确。然而在骨的吸收面牙周膜的继续附着和不断再附着的详细机制尚不完全明确。同样,在转折线上新骨过渡到较老的吸收骨面的固结情况也不完全了解。本研究的目的是提供有关这方面更详细的超微结构情况。材料和方法6支雄性Wistar albino 鼠,平均体重210克。乙醚麻醉。动物未施予矫治力,因本研究的目的是确定不受外力(正常生理情况下)牙齿移动时牙周膜的附着情况。为将来施予
The periodontal ligament collagen matrix attached to the alveolar bone deposition surface in the manner of Charpy's fiber support in the bone has long been known. However, the detailed mechanism of continued attachment and constant reattachment of the periodontal ligament in the bone absorption surface is not yet fully understood. Likewise, the consolidation of new bone to the older bone that absorbs bone on the turning line is not fully understood. The purpose of this study is to provide more detailed information on the ultrastructure in this area. Materials and Methods Six male Wistar albino rats, with an average body weight of 210 grams. Ether anesthesia. Animals were not given orthodontics because the purpose of this study was to determine the attachment of periodontal ligament to external forces (under normal physiological conditions) during tooth movement.
