近来,对囊肿摘除等手术所产生的骨缺损,采用颗粒状羟基磷灰石进行充填,而颗粒状磷灰石尚存在操作中颗粒飞溅,充填后颗粒溢出,填补处塑形困难等问题。因此,为了克服这些缺点,作者报告了试用磷灰石颗粒和纤维蛋白糊剂进行混合充填,获得了良好的效果。作者对2例根尖囊肿、1例根尖肉芽肿(3个部位)、2例慢性边缘性牙周炎(3个部位)、1例下颌骨囊肿共6个病例9个部位进行了临床应用。把气孔率55～60%的多孔质磷灰石粉碎为直径1～2mm 的磷灰石和气孔率45%、直径600μm 的磷灰石颗粒。将这种磷灰石与6.4%纤维蛋白原水溶液混合后,一边填入骨质缺损部位,一边加入
Recently, the removal of cysts and other surgical bone defects generated by the use of granular hydroxyapatite filling, and granular apatite particles still exist in the operation of the spill, the particles overflow after filling, fill at the formation of difficult problems. Therefore, in order to overcome these shortcomings, the authors report that good results have been obtained by mixing apatite particles and fibrin paste for filling. The author of 2 cases of apical cysts, 1 cases of apical granuloma (3 sites), 2 cases of chronic borderline periodontitis (3 sites), 1 case of 6 cases of mandibular cysts in 9 cases of clinical application . The porous apatite having a porosity of 55 to 60% is pulverized into apatite having a diameter of 1 to 2 mm and apatite particles having a porosity of 45% and a diameter of 600 μm. After mixing this apatite with a 6.4% aqueous solution of fibrinogen, the bone defect site was filled with
