种植体周围炎后牙槽骨丢失仍然是临床挑战。本研究旨在设计一种新型的生物活性牙科植入物,以适应因去除先前失败的植入物而导致的大骨缺损。

采用激光烧结添加剂3D打印技术制造Bio-ActiveITRI牙科植入物。在20只新西兰大白兔的股骨远端侧面开创了7.5毫米直径×7.0毫米深度的截骨缺损,以模拟去除失败的牙科植入物后的骨缺损。随机选择股骨远端一侧用于商业纯钛NobelActive™植入物(对照组),另一侧使用Bio-ActiveITRI Ti6Al4V多孔牙科植入物(ITRI组)。植入物植入后第4、8和12周处死动物。对样品进行了总体形态分析,射线照相检查,微CT评估和机械测试。

结果显示,在组织形态计量学评估和显微CT分析中,在ITRI植入物周围的间隙处观察到了活跃的新骨形成和良好的骨整合。Bio-ActiveITRI牙科植入物的生物力学参数明显高于商业对照样品。对于Bio-ActiveITRI牙科植入物,从规定的1个月至3个月的时间点,骨小梁的厚度减小,而骨小梁的分离度和总孔隙率增加;反映了Bio-ActiveITRI牙科植入物中周围骨组织的自然重塑。

综上所述,该研究结果表明,新型的多孔结构Bio-ActiveITRI牙科植入物可能具有修复重建的巨大潜力。
