将钛涂层３１７Ｌ接骨板植入电子线照射的犬右下颌骨体部，用透射电镜（ＴＥＭ）观察相邻骨膜超微结构变化，结果显示，钛涂层３１７Ｌ接骨板组相邻骨膜超微结构损伤比未喷涂钛层的３１７Ｌ接骨板对照组轻微。可能与未喷涂钛层的３１７Ｌ接骨板所释放出来的毒性较大的Ｃｒ、Ｎｉ离子对组织细胞的再损伤有关，而钛涂层３１７Ｌ接骨板表面呈纯钛相，不会造成组织细胞超微结构明显损伤
Titanium-coated 317L plate was implanted into the canine right mandibular body irradiated with electron beam. The ultrastructure of the adjacent periosteum was observed by transmission electron microscopy (TEM). The results showed that the adjacent periosteal superfine The structural damage was slightly lower than that of the 317L plate without titanium coating. Which may be related to the re-injury of tissue cells with the more toxic Cr and Ni ions released from the 317L plate without spraying the titanium layer. However, the surface of the titanium coating 317L plate with titanium phase does not cause ultrastructure of the cells Structure obvious damage
