Implant-supported immediate loading full-arch rehabilitation has been documented in the literature. More recently, computed surgical guides have frequently been used since they facilitate planning and performing surgical treatment without the need to raise a flap, thus reducing trauma and morbidity. This case report describes an immediate full-arch, fixed rehabilitation with full loading placed on four commercially available 3D-printed implants, with a 24-month follow-up. The implants were placed with the help of a digitally planned 3D-printed surgical guide. The provisional fixed prosthesis installed immediately was replaced after 3 months. At the time, the soft and hard tissue around the implants appeared stable, without signs of inflammation. The same situation was observed at the 24-month follow-up. Three-dimensional-printed implants seem to be a promising choice in this case. However, further clinical studies with longer follow-up periods are necessary to confirm their efficacy.
文献中已有关于种植体支持的即刻全口负重修复的记载。最近，由于计算机辅助手术导板可以在无需翻瓣的情况下辅助规划和执行手术治疗，从而减少创伤和发病率，因此经常被使用。本病例报告描述了一项即刻全口固定修复，采用四颗市售的 3D 打印种植体进行全负重，24 个月随访。种植体的植入是借助数字化设计的 3D 打印手术导板完成的。在术后 3 个月时，更换了临时固定修复体。此时，种植体周围的软硬组织看起来稳定，没有炎症迹象。在 24 个月的随访时同样如此。3D 打印种植体在这种情况下似乎是一种有前途的选择。然而，需要进一步的长期临床研究来证实其疗效。
