个体化预制钛支架复合松质骨修复犬下颌骨缺损

Custome-designed pre-cast titanium bracket combined with cancellous bone reconstruction of mandibular defect of dog

目的:对快速原型技术(RP技术)应用于下颌骨大面积缺损修复进行了初步研究。方法:对快速原型制造的个体化预制钛支架+松质骨修复犬下颌骨缺损与预成钛网修复进行了对照研究。结果:手术中可见个体化预制钛修复体和缺损区域形态相吻合,节省了大量时间。成骨效果与成品钛网+松质骨成骨效果相同。结论:RP技术在下颌骨大面积缺损修复的应用具有重要的临床意义及广阔的应用前景。

Objective To establish an animal digital model with rapid prototyping technology rebuilding mandibular defect. Methods Control experiment was made with titanium mesh and custom-designed titanium bracket on mandibular reconstruction. Results In surgery we could see that the custom-designed titanium bracket tallied with the shape of mandibular defect perfectly, with much fewer time. The effect of osteogenesis was same as titanium mesh′s. Conclusion RP is of great importance in construction of mandible defect.
