本文通过对21例因患肿瘤等原因而切除部分下颌骨的病例,采用立即植入一种新型的人工骨材料——生物活性玻璃陶瓷人工骨修复大型骨缺损(其中10例骨受植床有严重感染),术后观察到患者手术创口均、工期愈合,无全身和局部不良反应。经7～38月观察,未发现植入人工骨有松动、脱出及致敏现像,X线片复查见骨相接端有新骨长入。表明该人工骨有良好的组织、化学相容性及诱导骨生长能力和较强的抗感染能力,特别是用在局部有感染情况的立即植骨上,缩短了治疗时间、减少了病员痛苦,是一种理想的修复下颌骨大型缺损的好材料。
In this paper, 21 cases of resection of the mandible due to tumor and other reasons, the immediate implantation of a new type of artificial bone material - bioactive glass ceramic artificial bone to repair large defects (of which 10 cases of bone bed Severe infection), postoperative patients were observed surgery wounds, duration of healing, no systemic and local adverse reactions. After 7 to 38 months of observation, we found no implant artificial bone loose, prolapse and sensitization, X-ray examination to see the bone adjacent to the new bone length into. The results show that the artificial bone has good tissue, chemical compatibility, bone growth inducing ability and strong anti-infective ability, especially for the immediate bone graft with local infection, shortening the treatment time, reducing the patient's suffering, Is an ideal material to repair large defects of the mandible.
