In the past few decades, the rehabilitation of maxillary defects has posed a significant challenge for prosthodontists. The advent of zygoma implants presents a unique alternative for maxillary reconstruction while minimizing prosthetic complications. However, the placement of zygoma implants is not without risk. This report describes the application of a special self-developed surgical navigation system, AccuNavi, for the planning and subsequent precise placement of zygoma implants in patients with maxillectomy defects. The superimposition of the preoperative planning and the real placement demonstrated that all of the three zygoma implants were appropriately positioned and oriented. In the phantom experiment, the mean distance and angular deviations were 0.58 ± 0.18 mm and 1.12 ± 0.39 degrees, respectively. This preliminary use of the AccuNavi for the placment of zygomatic implants appears to be a reliable method for transferring the planning of a complex osteotomy to the actual surgical procedure. However, further multicenter clinical evaluations should be conducted to establish the predictability of this surgical technique.
在过去的几十年中，上颌骨缺损的修复对修复科医生来说是一个巨大的挑战。颧骨种植体的出现为上颌骨重建提供了一种独特的选择，同时最大限度地减少了修复体并发症。然而，颧骨种植体的放置并非没有风险。本报告介绍了一种特殊的自行开发的手术导航系统 AccuNavi 在接受上颌骨切除术的患者中用于规划和随后精确放置颧骨种植体的应用。术前规划与实际放置的叠加表明，三个颧骨种植体均被正确定位和定向。在体模实验中，平均距离和角度偏差分别为 0.58 ± 0.18 毫米和 1.12 ± 0.39 度。AccuNavi 初步用于颧骨种植体的放置，似乎是一种将复杂截骨术的规划转移到实际手术过程中的可靠方法。然而，应该进行进一步的多中心临床评估，以确定该手术技术的可预测性。
