拔牙后即刻植入羟基磷灰石微粒人工骨的临床应用研究

A Clinical Study on Immediate Implantation of Particulate Hydroxylapatite Artificial Bone after Teeth Extraction

目的 :研究拔牙后即刻植入羟基磷灰石微粒人工骨的治疗效果和并发症。方法 :6 5例患者拔牙后牙槽窝内即刻植入羟基磷灰石微粒人工骨 ,术后 1周、1月、3月分别复诊 ,进行临床及X线检查。结果 :6 5例患者伤口均顺利愈合 ,未发生术后出血、感染、羟基磷灰石微粒人工骨移位等术后并发症 ,同术前相比 ,牙槽嵴高度无明显降低。结论 :拔牙后即刻植入羟基磷灰石微粒人工骨可以维持牙槽嵴的高度 ,减少术后并发症 ,为以后进行义齿修复提供一个良好的基骨条件 。

Objective:The aim of this study is to investigate the effect and complication of immediate implantation of particulate hydroxylapatite artificial bone after teeth extraction.Methods:Particulate hydroxylapatite artificial bone was implanted into 65 extraction sockets after teeth extraction. All patients were followed up until 3 months after the operation. They are examined with clinical examination and X_ray examination to observe the effect and complication of the implantation operation.Results:The wound healed well in all cases without any complication. Compared to the alveolar ridge before teeth extraction, and the height of the alveolar ridge after teeth extraction didn't decrease.Conclusion:Implantation of particulate hydroxylapatite artificial bone after teeth extraction could maintain the height of the alveolar ridge and reduce the complication of teeth extraction. It would be helpful for the following prosthetic restoration. The immediate implantation of artificial bone is therefore needed further study.
