Abstract：
Reconstruction of continuity defects following osteonecrosis in multimorbid patients is challenging. In all cases of the predescribed palliative treatment method for alloplastic mandible reconstruction, plate fractures were detected in follow-up. We hypothesized that a modification could avoid these fractures, leading to stable long-term results.
This retrospective study compares the original method with a modification using single, laser-sintered CAD-CAM plates instead of manually bent miniplates. The predescribed shuttering technique was used to reconstruct the mandible in its original shape with bone cement.
Uneventful wound healing was observed in 86% of the cases after modification of the method. No implant or plate fracture occurred.
The presented method should be considered as a treatment option for mandible reconstruction in elderly, multimorbid patients in palliative situations. The results of this study suggest that the modification of the method leads to significantly improved long-term stability. Donor site morbidity is avoided with this method of palliative surgery.

摘要：
背景：多类型骨坏死患者连续性缺损的重建具有挑战性。在所有采用上述姑息治疗方法进行同种异体下颌骨重建的病例中，在随访中发现钢板骨折。我们假设修改可以避免这些骨折，带来稳定的长期结果。
方法：这项回顾性研究将原始方法与使用单，激光烧结CAD-CAM板，而不是手动弯曲的微型板。使用预先描述的模板技术用骨水泥重建下颌骨的原始形状。
结果：改良方法后，86％的患者伤口愈合不畅。无植入物或钢板骨折。
结论：所提出的方法应被视为老年人下颌骨重建的治疗选择，缓解情况下的多患者。这项研究的结果表明，方法的改进导致长期稳定性的显着改善。使用这种姑息性手术方法可以避免供体部位的发病率。
