摘要
目的:观察人羊膜植入临床拔牙创后对牙槽骨愈合的影响。方法:选用来本院需拔除双侧下颌第二前磨牙正畸治疗的患者20例,右侧拔牙创植入人羊膜作为试验组,左侧拔牙创作为空白对照。术后1、2、3个月拍口腔全景片,观察新骨形成情况及牙槽嵴吸收评价拔牙创愈合情况。结果:术后1周牙龈愈合及术后1、2、3个月拔牙创新骨形成量试验组优于对照组,术后1、2、3个月牙槽嵴吸收高度试验组均明显低于对照组(P<0.01);每月牙槽嵴吸收量第1、2个月试验组均低于对照组(P<0.01),第3个月两组无明显差异(P>0.01)。结论:临床拔牙创植入人羊膜能促进拔牙创的早期愈合,保存牙槽嵴高度。
Objective：To observe the effect of human amniotic membrane planted in tooth extraction wound in the knitting of alveolar bone.Method：20 patients who need to extract the two lower second premolars because of orthodontic treatment in our department were chosen. The right side were considered as the experimental group with the human amniotic membrane implanted in tooth extraction wound, and the left as blank control group. Then the condition of knitting after tooth extraction and the absorption of alveolar bone were observed by taking oral panoramic pieces respectively in the first,second and third months,to evaluate the knitting of the tooth extraction wound. Result：The healing of the gingiva in the experimental group was better than in the control group one week after the operation.The same happened in the new bone formation in the tooth extraction wound.The height of alveolar ridge absorbed in experimental group were significantly lower than control group in the 1st, 2nd, 3rd month（P〈0.01）.The height of alveolar ridge absorbed each month in experimental group were also lower than those of control group both in 1st and 2nd month（P〈0.01）,but two groups had no obvious difference in 3rd month（P〉0.01）.Conclusion：Human amnion can promote the healing of tooth extraction wound in early days and keep the height of alveolar ridge.
