The reconstruction of acquired mandibular defects due to ablative tumor surgery or traumatic injuries is still challenging. The gold standard in such treatment is application of reconstructive titanium plates, which should be contoured and adapted to the defect as much as possible because of their influence on postoperative functional and esthetic results. Traditionally, plate bending is achieved by trial and error intraoperatively. Use of stereolitography (STL) models potentially could reduce the risk of incorrect contouring as well as operating time. On the other hand, fabrication of STL is time-consuming and costly. However, we found only one experimental study dedicating to virtual plate bending in the literature. The aim of this article was to demonstrate clinical application of a method of virtual bending of reconstructive plate for mandibular defect bridging. No significant complications occurred, and satisfactory functional and esthetic results were achieved in all cases. We found this technique precise and applicable in cases of reconstruction of mandibular defects.
因肿瘤切除手术或外伤导致的下颌骨后天性缺损的重建仍然具有挑战性。此类治疗的金标准是应用重建钛板，由于其对术后功能和美观效果有影响，应尽可能对其进行塑形并使其与缺损相适配。传统上，钢板弯曲是在术中通过反复试验来完成的。立体光刻（STL）模型的使用有可能降低轮廓塑形错误的风险以及手术时间。另一方面，STL模型的制作既耗时又昂贵。然而，我们在文献中仅发现一项致力于虚拟钢板弯曲的实验研究。本文的目的是展示一种用于下颌骨缺损桥接的重建钢板虚拟弯曲方法的临床应用。未发生明显并发症，所有病例均取得了满意的功能和美观效果。我们发现该技术精确且适用于下颌骨缺损的重建病例。
