Dental autotransplantation is an effective alternative to conventional dental treatment, and it involves removing a tooth and repositioning it in a new position within the same patient. Although this procedure might pose more intraoperative challenges, it provides a great solution for replacing missing teeth or aiding difficult eruption in young patients. This prospective method is also advocated as a use of treatment for unrestorable teeth. The success rates of autotransplantation cases with and without replicas were compared in a retrospective analysis of the data. By reducing donor tooth manipulation and ensuring a proper fit and positioning in the recipient socket, replicas significantly increased success rates of the procedure. CBCT scans were used to collect data. Data exported to the Mimics system were then processed in order to achieve a model of the donor tooth. Additive manufacturing technology was used to create the replicas. Specialized biocompatible material was used. Details of the replantation site and the donor tooth requirements were described, as well as the step-by-step surgical technique. For the best results, variables, like patient selection, surgical technique, and long-term monitoring, were found to be essential. The study highlights the significance of dental professionals and biomedical engineering staff working together to develop standard operating procedures and achieve predictable outcomes in autotransplantation procedures. The results suggest that 3D printed replicas could be a useful tool for improving the effectiveness and success of dental autotransplantation.
牙自体移植是传统牙科治疗的一种有效替代方法，它包括拔除一颗牙齿并将其重新定位到同一患者体内的新位置。尽管此手术可能会带来更多术中挑战，但它为替换缺失牙齿或帮助年轻患者解决牙齿萌出困难提供了很好的解决方案。这种前瞻性方法也被提倡用于治疗无法修复的牙齿。在对数据的回顾性分析中，比较了有复制体和无复制体的自体移植病例的成功率。通过减少供体牙的操作，并确保在受体牙槽窝中合适的匹配和定位，复制体显著提高了该手术的成功率。使用CBCT扫描收集数据。然后对导出到Mimics系统的数据进行处理，以获得供体牙的模型。采用增材制造技术制作复制体。使用了专门的生物相容性材料。描述了再植部位和供体牙要求的细节，以及分步手术技术。为了获得最佳效果，发现患者选择、手术技术和长期监测等变量至关重要。该研究强调了牙科专业人员和生物医学工程人员共同努力制定标准操作程序并在自体移植手术中实现可预测结果的重要性。结果表明，3D打印复制体可能是提高牙自体移植有效性和成功率的有用工具。
