The purpose of this study was to know the process of tissue response and regeneration in the palato-maxillary suture under tensile forces.
Sutural tissue changes after 3, 7, 14, 28, 56 days of suture expansion were examined histologically and fluorescently.
It was found that a cyst-like zone appeared in the conjuncture of bony front and sutural connective tissue at the early stage of sutural expansion. Then a great amount of osteoblasts and fibroblasts proliferated. New bone deposited along the septum and the front of the cyst until the new bone front formed and the suture restored its original morphology.
The findings suggested that sutural expansion be a process of bone tissue regeneration and fibrous tissue repair.
本研究旨在了解在拉力作用下腭-上颌缝的组织反应和再生过程。
在缝线扩张3、7、14、28、56天后，对缝合组织变化进行组织学和荧光检查。
发现在缝线扩张早期，骨前缘与缝合结缔组织的结合处出现一个囊肿样区域。然后大量成骨细胞和成纤维细胞增殖。新骨沿着隔膜和囊肿前缘沉积，直到新骨前缘形成，缝线恢复其原始形态。
研究结果表明，缝线扩张是一个骨组织再生和纤维组织修复的过程。
