3D打印辅助颌面骨缺损与畸形的临床精准修复重建

The value of 3D print technique in the precious reconstruction of the defects and malformations of maxillofacial bone

目的:探讨3D打印技术在颌面骨缺损与畸形的修复重建手术中的应用价值。方法:治疗颌面骨缺损与畸形手术病例6例。术前行三维CT扫描、重建并3D打印1∶1实物模型。根据模型进行疾病诊断、手术设计及植入物的预制。结果:3D打印的头模全方位显示了骨缺损及病变区域的状况,实现了生物修复板的术前、体外精确预制;实证了头影测量分析的结果,实现了真正意义上的模型外科;利用镜像模型进行重建板精确弯制,恢复了患者面型及下颌骨高度。结论:3D打印能全方位、直观、精确地显示颌面骨的三维空间关系,对于颌面骨缺损与畸形的修复重建手术有极大的临床指导价值。

Objective： To study the value of 3D print technique in the reconstruction of the defects and malformations of oral and maxillofacial bone. Methods ： 6 cases with defects and malformations of oral and maxillofacial bone were examined by CT scanning, treated by the implantation of 3D printed implants. Results： Before operation, 3D printed model clearly showed the status of the defects and malformations for the precious preoperative implant shaping. The implants for the reconstruction were prepared by 3D print teehinique. Perfect reconstruction of the defects was achieved. Conclusion： 3 D printing technology exerts promising values in the precious and effective reconstruction of the defects and malformations of maxillofaeial bones.
