A completely digital workflow is described for the immediate restoration of a fractured fiber post with a digitally prefabricated definitive restoration using 3-dimensionally printed guides. The geometric morphology and axis of the root canal were digitally determined by using cone beam computed tomography to localize the 3-dimensional position of the fractured fiber post. A virtual drill modeled on the shape of the fractured post was fabricated and customized for removal of the post by using a guide to facilitate the intraoral transfer of the drilling procedure. A titanium post-and-core and crown had been virtually predesigned and fabricated before the procedure, and 2 digital guides were designed for their placement. All guides were 3-dimensionally printed. By following this workflow, the removal of the fractured fiber post and immediate definitive restoration were completed in 1 visit, facilitating a more efficient, predictable, and straightforward treatment.

描述了一个完全数字化的工作流程，用于使用 3 维打印指南使用数字预制最终修复体立即修复断裂的纤维桩。通过使用锥形束计算机断层扫描定位断裂纤维桩的 3 维位置，以数字方式确定根管的几何形态和轴。以骨折桩的形状为模型制作并定制了一个虚拟钻头，用于通过使用导向器移除桩，以促进钻孔过程的口内转移。钛桩核和牙冠在手术前几乎已预先设计和制作，并设计了 2 个数字导板用于放置。所有指南都是 3 维打印的。通过遵循此工作流程，
