腭板HA复合人工骨植骨术对上颌骨生长发育的相关研究

The effect of artificial bone implantation in cleft palate on the development of maxilla

目的研究腭板HA复合人工骨植骨术对患者上颌骨三维方向上生长发育的影响。方法腭板骨缺损的先天性II度腭裂患者40例,随机分为对照组和植骨组,植骨组腭板骨缺损利用HA复合人工骨修复,所有患者年满16周岁时复诊,行X线头影测量及牙颌模型测量对比分析。结果植骨组与对照组在上颌骨长度及高度发育上差异均无统计学意义(P>0·05);植骨组与对照组在上颌骨后部宽度发育上差异有统计学意义(P<0·05),植骨组上颌骨宽度明显大于对照组。结论腭板植骨术对上颌骨宽度的发育存在明显的促进作用,在提倡序列治疗的过程中应该考虑对硬腭骨缺损进行植骨修复。

Objective To research the influence of palate bone implantation to the growth of maxilla in three dimensional direction. Methods 40 patients of congenital cleft palate type Ⅱ with palate board damage were stochastically divide into the comparison group and bone planted group. In bone planted group, HA-Bone cement was used to repair palate tabulare damage. All patients are 16 full year old, cephalometric radiograph and tooth cast model were measured and contrast analysis was applied. Results Planted bone group and the comparison group does not have the significance difference in both the maxilla length and maxilla highness（ P 〉 0.05 ） ; But there was significance difference in the width of post- part of the maxilla （ P 〈 0.05 ）. Conclusions It could promote the growth of maxilla width in use of bone implantation, that advocated the hone repair in the sequence treatment process in cases of the hard palate bone damage.
