Development of intraosseous fibers was studied in mandibles of Swiss white mice, age 17 days to 45 days. Light microscopic (LM) and high-voltage electron microscopic (HVEM) techniques were used. In LM, Wilder's reticular stain revealed intraosseous fibers throughout the interdental septum by day 17. fibers were composed of unit collagen fibrils with abundant interfibrillar matrix. As development proceeded, fibers exhibited less interfibrillar matrix. Channels surrounding the intraosseous fibers became evident. Anchoring fibers attached the intraosseous fiber to bone. Fibroblasts appeared to be absent, suggesting that maintenance of the intraosseous fiber might be the function of the osteocyte. The presence of intraosseous fibers suggested a reevaluation of the fibrous attachment of teeth to bone. The concept of intraosseous fibers may simplify concepts of tooth movement and approximal drift.
对17日龄至45日龄瑞士小白鼠下颌骨内骨纤维的发育进行了研究。采用了光学显微镜（LM）和高压电子显微镜（HVEM）技术。在光学显微镜下，到第17天时，怀尔德网状染色显示整个牙间间隔内均有骨内纤维。纤维由单位胶原纤维组成，具有丰富的纤维间基质。随着发育的进行，纤维的纤维间基质减少。骨内纤维周围的通道变得明显。锚定纤维将骨内纤维附着于骨。似乎不存在成纤维细胞，这表明骨内纤维的维持可能是骨细胞的功能。骨内纤维的存在提示对牙齿与骨的纤维附着进行重新评估。骨内纤维的概念可能会简化牙齿移动和邻面漂移的概念。
