- 摘要:
- 目的观察坚固内固定对兔下颌骨发育的影响。方法选用70天龄新西兰白兔10只，右侧下颌骨为实验组，造成下颌骨体部骨折同时行钛板固定；左侧下颌骨为对照组，不造成骨折，仅植入定位钛钉。术后3个月取下颌骨进行大体观察、MicroCT扫描及组织学观察。应用SPSS14.0软件包进行单因素方差分析。结果实验组钛板固定区域颊侧骨皮质厚度、骨体积分数均小于对照组（P<0.05)，骨密度的差异不大（P>0.05）。两组之间下颌骨的生长量未见明显差异，所有动物未出现两侧下颌骨发育不对称、中线偏斜及咬合关系紊乱的现象。结论坚固内固定对下颌骨发育无明显抑制作用，仅影响发育期下颌骨成骨质量，造成局部骨皮质厚度、骨体积分数不同程度的减小。
