CAD/CAM技术辅助下使用Medpor®精确修复下颌轮廓凹陷

         

摘要

Objective To report a semi-digital technique to get an optimal fitting custom-made high-density porous polyethylene ( Medpor) for reconstruction of mandibular contour defects with the help of CAD/CAM and reverse engineering technology. Methods 17 patients suffering from defects of mandibular contour registered for the novel techniques to reconstruct the mandibular contour. For each patient, computed tomography ( CT) data were collected, CAD/CAM, reverse engineering and rapid prototyping ( RP) by three-dimensional (3D) printing were used to fabricate the preoperative individualized geometric model. The mandibular contour defected ar-eas were reconstructed by modeling and implanting Medpor. Results All cases, except one with delayed infection whose implantation material was removed later on, recovered quite well. The follow-up observation showed that the previous defect zones had been accu-rately reconstructed, and a symmetric bony contour as well as an appealing facial appearance was acquired. Conclusion Individual-ized Medpor implant based on CAD/CAM can accurately reconstruct defect of mandibular contour.%目的:报导一种通过个体化Medpor®来重塑下颌骨轮廓的方法,评价其治疗效果并讨论适应证。方法选取四川大学华西口腔医院下颌骨轮廓凹陷病例17例,采集其CT数据,运用CAD/CAM、镜像反求、快速成型及3D打印技术设计并精确制作出手术模板,雕刻塑形出个性化Medpor®,并指导准确植入体内,修复下颌凹陷畸形。结果除1例植入体因迟发性感染取出外,其余患者恢复良好,复查定位照相对比示:患者下颌轮廓凹陷均得到较好修复,对称性得到明显改善,医患均对手术效果感到满意。结论在CAD/CAM技术辅助下,运用Medpor®可以精确修复下颌骨轮廓凹陷,是一种值得推广的方法。
