干槽症是下颌阻生智齿拔牙术后常见并发症,国内外文献报告发病率为14—30％。对于干槽症的防治,近年来国内外报告方法较多,本文报告了使用羟基磷酸钙颗粒人工骨(Hydroaylapatite,以下简称HAP)填充阻生智齿拔牙窝预防干槽症的临床研究结果,这种新方法国内外文献尚无报道。材料和方法一、应用我院与航天部621所研制的高纯羟基磷酸钙颗粒人工骨、四川大学物理系研制的致密多晶羟基磷灰石微粒人工骨,二种人工骨经生物安全性检测和动物实验证实为无毒,生物相容性良好,有明显加快骨组
Dry socket disease is a common complication after mandibular impacted wisdom tooth extraction, and the incidence in domestic and foreign literature is 14-30%. For the prevention and treatment of dry socket disease, there are many reports methods at home and abroad in recent years. This paper reports the results of clinical studies on the prevention of dry socket disease by using Hydroxylapatite (HAP) The new method has not been reported at home and abroad. Materials and methods First, the application of our hospital and the Ministry of Space 621 developed high purity hydroxy calcium phosphate particles artificial bone, Sichuan University Department of Physics developed dense poly hydroxylated hydroxyapatite artificial bone, two artificial bone biosafety testing And animal experiments confirmed non-toxic, good biocompatibility, there is significantly accelerated bone group
