摘要： 目的 ·采用逆向工程技术原理，设计制作截骨导板应用于腓骨瓣修复下颌骨缺损。方法 ·选取 5例复杂下颌骨缺损患者作为研究对象，在其三维打印的下颌骨重建模型上预先弯制重建钛板，通过 CT扫描重建下颌骨、钛板、钛钉的三维图像，采用面 –面配准的技术逆向回原始下颌骨及腓骨表面，制作带有重建钛板钉孔空间位置的截骨导板。在术中，通过截骨导板截骨并确定重建钛板固定位置，完成多节段腓骨瓣的精确拼接。结果 · 5例患者均获得满意的临床疗效；术前设计与实际手术的截骨误差可以满足临床应用，其中最大误差为 (3.53±2.33) mm，角度误差为 3.31.±1.48.。结论 ·采用逆向工程技术原理设计的腓骨瓣截骨导板可以满足临床使用的要求，临床疗效满意。

Abstract:

Objective · To design osteotomy templates for the construction of mandibular defectusing fibular flap in a reverse engineering technique approach. Methods · Five patients with mandibular defect were enrolled and their treatments were designed in a three-dimensional (3D) virtual planning software package. The 3D printing model with shaped reconstruction plate and titanium-screws were under CT scanning and the image was reconstructed and registered back to the original mandible and fibula in a surface-best-fit method. Then the osteotomy template with screw holes of shaped reconstruction plate was designed and fabricated. The reconstruction of mandible with multiple fibular segments was guidedthe osteotomy template. Results · All the five patients were discharged successfully with satisfied outcome. The deviation between virtual plan and actual results were calculated: max deviation （3.53±2.33) mm and the angle deviation 3.31.±1.48.. Conclusion · The accuracy of the osteotomy template is satisfied and can be applied to the clinical use.
