摘要
目的:研究如何将快速原型技术与腓骨平行折叠技术相结合,以更好地指导下颌骨重建。方法:下颌骨肿瘤切除术后复杂缺损重建患者6例,术前计算机辅助模拟手术,应用快速原型技术制作腓骨平行折叠后的颌骨模型并预制钛板形态,参照模型,指导术中腓骨骨段精确摆放位置。结果:所有患者创口一期愈合,结合放射核素扫描及数字全景片检查,证实移植腓骨与剩余颌骨完全愈合,腓骨位置与术前设计吻合,患者术后咬合关系良好,面形恢复满意。结论:利用快速成型技术指导腓骨平行折叠,能够更精确地重建下颌骨的外形,有利于保持咬合关系和髁突位置,为二期种植义齿修复奠定基础。
PURPOSE： To evaluate the usefulness of rapid prototyping technique and double barrel fibular graft technique in mandible reconstruction.METHODS： Six patients underwent reconstruction of large segmental mandibular defects with double barrel fibular osteocutaneous graft techniques.3-dimensional mandibular models were made by rapid prototyping technique to ensure that the fibular bones were placed accurately and matched with the remaining mandible segment.RESULTS： Of all patients,the fibular osteocutaneous grafts survived completely,there was no evidence of recurrence.Good appearance and occlusion were achieved in all sufferers after treatment.Panoramic radiograph and three-dimensional CT scan revealed that the locations and heights of the fibular bones met the preoperative design.CONCLUSION： The use of rapid prototyping technique can improve the accuracy of double barrel fibular location in mandible reconstruction,maintain the function of temporomandibular joint and regenerate a symmetrical facial contours.
