摘要
目的:观察种植牙胚的牙冠发育情况。方法:选择出生后(PN)8天的SD大鼠,完整剥离第一磨牙牙胚,种植到母鼠肾被膜下,4周后取材观察。结果:种植牙胚的牙冠继续发育,冠周有新生牙槽骨,部分釉质外侧生成骨样结构。结论:牙胚种植到肾被膜下后牙冠可正常发育。
Objective: To observe the development of tooth crown after the implantation of tooth germ.

Af- ter 4 weeks, implanted germs were harvested and the development of tooth crown was observed. Result: Tooth crown devel- oped normally. New alveolar bone was observed surround the tooth crown.
