摘要/Abstract

摘要： 目的评价前牙及前磨牙拔除后应用国产羟基磷灰石人工骨粉进行拔牙位点保存的效果。方法：将30名患者双盲随机分为实验组（15人）与对照组（15人），实验组拔牙后即刻填充国产天博骨粉，对照组拔牙后即刻充填瑞士Bio-Oss骨粉，术后即刻和6个月复查时拍摄锥形束CT（CBCT），观察牙槽嵴骨高度及宽度的变化。牙槽嵴骨高度通过牙槽嵴长轴测得，牙槽嵴骨宽度于牙槽嵴顶下方1 mm(W1)，4 mm(W2)，7 mm(W3)处测得。结果：实验组牙槽骨高度平均下降（6.86±11.92）%，宽度平均减少为：W1=（16.17±14.94）%，W2=（10.39±17.61）%，W3=（5.17±12.03）%。对照组牙槽嵴骨高度平均下降（9.87±8.78）%，宽度平均减少为：W1=（17.33±22.60）%，W2=（9.89±13.39）%，W3=（2.29±10.19）%。实验组和对照组在牙槽骨保存方面无明显差异（P>0.05）。结论：国产羟基磷灰石人工骨粉在位点保存方面与Bio-Oss骨粉具有基本相同的作用。

Abstract: Objective:In order to evaluate the effect of domestic hydroxyapatite artificial bone graft on site preservation after anterior and premolar extraction .Methods: The 30 patients were randomly divided into two groups: test group(15 patients), who were filled with domestic artificial bone graft (Bio-osteon, BEIJING YHJ,Beijing) and control group(15 patients), who were filled with Bio-Oss(Geistlich,Switzerland), and were inspected with cone-beam computed tomography（CBCT）immediately after the filling, and at six months after. The CBCT was used to evaluate the changes of both the height and the width of the alveolar ridge. The vertical dimensions of alveolar process was determined by alveolar ridge long axis. The horizontal dimensions was assessed at three different areas measured from the top of the crest: 1 mm (W1), 4mm (W2) and 7 mm (W3). Results: The mean vertical loss of the alveolar bone for the test group was（6.86±11.92）%. The width of the alveolar ridge in the test group decreased by W1=（16.17±14.94）%, W2=（10.39±17.61）% and W3=（5.17±12.03）%. The control group showed vertical loss of （9.87±8.78）%,and the width of the alveolar ridge in the control group decreased by W1=（17.33±22.60）%, W2=（9.89±13.39）% and W3=（2.29±10.19）%. There was no significant difference between the test group and the control group（P>0.05）. Conclusions：The domestic hydroxyapatite artificial bone graft has the same effect as the Bio-Oss in site preservation.
