固骼生人工骨修复83例颌骨囊肿术后骨缺损临床分析

Clinical analysis on the nova bone restores 83 cases of postoperative defects of jaw cysts

[背景]观察固骼生人工骨在颌骨囊肿术后填充颌骨缺损修复中的应用效果.[病例报告]按照常规方法给83例颌骨囊肿病例摘除囊肿病变组织,用自体血液充分搅拌固骼生人工骨后填充颌骨囊肿缺损.83例应用固骼生后未见明显局部和全身反应,其中81例修复成功,X线检查结果示固骼生与宿主骨紧密接触,无脱落,术后随访2年见骨缺损被完全修复.83例中2例因切口缝合部位粘膜撕裂而修复失败.[讨论]固骼生安全无毒,使用方便,易塑性及生物相容性良好,可替代自体骨材料应用于颌骨囊肿术后骨缺损的修复中.

BACKGROUND To study clinical significance of the nova bone for restoring postoperative defects of jaw cysts.CASE REPORTS In 83 cases of defects of jaw cysts,the pathological cyst wall was excised by conventional method,and the defects of jaw cysts were filled by using autologous blood fully stirred with the nova bone.All of 83 cases with applied the nova bone had no obvious local and systemic reactions,and X-ray examination showed that in 81 cases the nova bone had closely contacted with the host bone and had no defluvium,and jaw defects were fully restored after following up two years,in which 2 cases had failure because the tunicae mucosa of suture was lancinated.DISCUSSION The nova bone is safe,non-toxic,easy to use,plastic property and good biocompatibility,and might be substituted for the autologous bone in restoring the postoperative defects of jaw cysts.
