植体基台周围两次植骨

60岁男以前就害怕牙科治疗,一年前做一侧肾上腺切除,现在更紧张,不过挺配合。右上6手机切断拔除,虽然近中颊侧牙槽窝破坏厉害,中隔还很大(图一:S),利用导板顺利完成钻洞和提升术(图二:*)。植入正式植体后,放置第一轮粘性骨粉,至植体水平(确保植体深部周围没有缺失)而不影响基台置入,近中有不足之处(图三:*),第二轮骨粉补充(图四),最后覆盖PRF膜,临时牙冠固定。The crown/abutment/implant are found to have mild mobility 4.5 months postop, as related to #19 infection.  A healing screw is placed.  One month later, the wound heals; the bone density in the sinus increases (Fig.5 *), while that coronal to the implant decreases (^).愈合帽放置4个月,伤口还没有完全愈合,翻瓣后发现远中螺纹表面肉芽组织覆盖,去除后者,第一螺纹暴露。放置愈合基台后,从颊侧往远中缺陷填入骨粉(图六:*),缝合,覆盖树脂敷料。
