作者用致密多晶羟基磷灰石HA加骨形成蛋白(BMP)和少量碘仿的复合材料作为根尖切除术后骨缺损的填充物,同时分别用HA加少量碘仿和用搔刮骨面使新鲜血液充盈骨缺损部为对照,进行一年临床观察发现复合材料填充骨缺损,术后3个月填充物与骨边缘有明显骨小梁形成,6个月骨腔内密度和周围骨组织均匀一致。而对照组6～12个月才开始见填充物边缘有骨小梁形成。说明BMP与HA复合材料具有很强的骨引导作用,利于骨的重建,是一种良好的颌骨腔性骨缺损的填充材料。 The authors used dense poly hydroxylated hydroxyapatite HA plus bone morphogenetic protein (BMP) and a small amount of iodoform composite material as a filler after apical resection of bone defects, respectively, with a small amount of HA plus iodoform and scraping bone surface One year clinical observation showed that the composite filled bone defects, and the trabecular bone formed at the edge of the filler and the bone at 3 months after operation. The bone density at 6 months and the surrounding bone tissue Uniform. The control group 6 to 12 months to see the edge of the filler trabecular bone formation. BMP and HA composite material has a strong role in guiding the bone, which is conducive to the reconstruction of bone, which is a good filling material of the jawbone cavity defects.
