Abstract:

摘要 目的:探讨应用3D打印技术制作个性化植入体在修复下颌骨缺损中应用的临床效果。方法:选择下颌骨节段性缺损患者3例,术前均行下颌骨CT扫描后三维重建获得数字化下颌骨模型,其中2例应用3D打印技术制作下颌骨树脂模型,术前根据实体模型完成重建板的个体化塑形;1例将设计完善的下颌骨植入体数据输入钛合金3D打印设备,直接获得带髁状突的个性化植入体。按术前设计对病变下颌骨行节段性切除,植入个性化下颌骨植入体,或同期行髂骨移植。结果:将3D打印技术应用于下颌骨缺损修复,个性化植入体术中就位顺利,操作简便,髂骨塑形快而准确。随访3~11个月,患者对面形满意,咬牙合关系正常稳定,植入体无松动、移位及脱落。结论:将3D打印技术应用于修复下颌骨缺损,不仅缩短了手术时间,减少了手术创伤,同时也提高了下颌骨重建的精确性,达到了美观与功能兼备的效果。为下颌骨仿真修复提供了一条快速有效的途径
