Cutting-edge patient-specific surgical plates (PSSPs) are supposed to improve the efficiency, precision, and functional outcomes of mandibular reconstruction. This study characterized the premium role of PSSPs in precise surgery and explored their working principles in computer-assisted mandibular reconstruction (CAMR).
The PSSPs-enhanced surgical precision was investigated through the model surgery and representative cases. Spatial deviations of reconstruction were characterized by comparing the reconstructed mandible with the virtually designed mandible. Working principles of PSSPs were distinguished by a review of evolving surgical techniques in CAMR.
In the model surgery, spatial deviations between the virtually planned mandible and the reconstructed mandible were 1.03 ± 0.43 mm in absolute distance deviation, 1.70 ± 1.26 mm in intercondylar length, and 1.86 ± 0.91 mm in intergonial length in the study group of PSSPs, significantly smaller than in the control group of conventional prebent surgical plates. Meanwhile, in the study group, distance deviations were 0.51 ± 0.19 mm in bone-plate distance and 0.56 ± 0.28 mm in drilled screw holes, indicating the art of matching structures and holes. The PSSPs-enhanced CAMR was further demonstrated in three representative cases of mandibular reconstruction. Finally, four primary techniques of CAMR were summarized based on a review of 8,672 articles. The premium role of PSSPs was distinguished by the benefits of matching structures and holes.
The PSSPs-enhanced surgical precision was verified through the model surgery and demonstrated in human surgery. Compared to other surgical techniques of CAMR, PSSPs contributed to the precise surgery by the art of matching structures and holes.
前沿的个性化手术钢板（PSSP）理应能提高下颌骨重建的效率、精度和功能效果。本研究阐述了PSSP在精准手术中的重要作用，并探究了其在计算机辅助下颌骨重建（CAMR）中的工作原理。
通过模型手术和典型病例研究PSSP提高手术精度的情况。通过将重建的下颌骨与虚拟设计的下颌骨进行比较，来确定重建的空间偏差。通过回顾CAMR中不断发展的手术技术来明确PSSP的工作原理。
在模型手术中，PSSP研究组虚拟规划的下颌骨与重建的下颌骨之间的空间偏差，绝对距离偏差为1.03±0.43毫米，髁突间长度为1.70±1.26毫米，角间长度为1.86±0.91毫米，显著小于传统预弯手术钢板对照组。同时，在研究组中，骨板距离的距离偏差为0.51±0.19毫米，钻孔螺丝孔的距离偏差为0.56±0.28毫米，表明了结构与孔匹配的技术。在三个下颌骨重建的典型病例中进一步证明了PSSP增强的CAMR。最后，在回顾8672篇文章的基础上总结了CAMR的四种主要技术。PSSP的重要作用通过结构与孔匹配的优势得以体现。
通过模型手术验证了PSSP提高手术精度，并在人体手术中得到了证明。与CAMR的其他手术技术相比，PSSP通过结构与孔匹配的技术有助于实现精准手术。
