Abstract：
UNASSIGNED: Subperiosteal implants might be the future first-line treatment in patients with compromised alveolar ridges, although the use of proper techniques and pre-surgical imaging is required to ensure treatment success.
UNASSIGNED: Severe bone loss puts the success of endosseous implants at risk. This technical report aims to introduce the subperiosteal implants (SPIs) created through additive manufacturing. A case study is presented, outlining the process and strategies employed to fully restore a maxillary structure using a customized subperiosteal implant. The patient, who had previously faced disappointment with traditional endosseous implants, received a customized SPI. A detailed 3-year follow-up is also provided. The design of the subperiosteal framework and abutments is based on digital records of the patient\'s jaw structure and a radiographic stent during occlusion. This ensures optimal placement within the dental arch. The implant and abutments are then three-dimensional (3D) printed using a titanium alloy, while a provisional denture is 3D-printed using polymer materials. SPIs offer a viable alternative for individuals with severe jaw bone degeneration, as demonstrated in this report detailing their application in complete maxillary restoration. This patient-specific, prosthesis-driven approach avoids the need for bone grafting and enables immediate functional recovery through a single surgical procedure.

摘要：
■骨膜下植入物可能是牙槽脊受损患者未来的一线治疗方法，尽管需要使用适当的技术和术前成像来确保治疗成功。
■严重的骨丢失使骨内植入物的成功处于危险之中。本技术报告旨在介绍通过增材制造制造的骨膜下植入物（SPI）。提出了一个案例研究，概述了使用定制的骨膜下植入物完全恢复上颌骨结构的过程和策略。病人,以前对传统的骨内植入物感到失望，收到定制的SPI。还提供了详细的3年随访。骨膜下框架和基台的设计基于患者颌骨结构的数字记录和闭塞期间的影像学支架。这确保了在牙弓内的最佳放置。然后使用钛合金对植入物和基台进行三维（3D）打印，而临时义齿是使用聚合物材料3D打印的。SPIs为严重颌骨退化的个体提供了可行的替代方案，如本报告所示，详细介绍了它们在完全上颌骨修复中的应用。这个病人特有的，假体驱动的方法避免了骨移植的需要，并通过单一的外科手术使功能立即恢复。
