Abstract：
This technical note aims to present a recently developed computer-guided protocol characterized by titanium-reinforced stackable surgical guides during post-extractive implant placement and subsequent immediate loading. A full maxillary edentulism was rehabilitated with one-piece implants, starting from a pre-existing removable denture. 3D digital scans of the removable denture and upper and lower arches were performed. On this basis, a prototype with ideal esthetic and functional outcomes was realized and replicated into a custom-made radiological stent with markers. The superimposition of STL and DICOM files allowed virtual planning of one-piece implants in the ideal prosthetically driven position. The stackable guides, composed of a fixed base template and additional removable components, were then realized. The fixed template, initially secured with anchor pins to the bone, was no longer removed. The removable components, which were screwed to the base template, were used to perform implant surgery and immediate prosthetic loading. No surgical complications occurred, the implants achieved a minimum insertion torque of 35 Ncm, and immediate prosthetic loading was performed. The base template allowed for the maintenance of a fixed reference during the entire workflow, improving the transition between the digital project, the surgical procedure, and the prosthetic rehabilitation.
摘要：
本技术说明旨在介绍一种最近开发的计算机引导协议，其特征是在拔出后的植入物放置和随后的立即装载过程中使用钛增强的可堆叠手术引导件。用一件式植入物修复了上颌骨全裂，从预先存在的可摘义齿开始。对可摘义齿和上下牙弓进行了3D数字扫描。在此基础上,实现了具有理想美学和功能结果的原型,并将其复制到带有标记物的定制放射支架中.STL和DICOM文件的叠加允许在理想的假肢驱动位置虚拟规划单件植入物。可堆叠的指南，由固定的基础模板和附加的可拆卸组件组成，然后意识到。固定模板，最初用锚定销固定在骨头上，不再被删除。可拆卸组件，它们被拧到了基础模板上，用于进行植入手术和立即加载假体。无手术并发症发生,植入物实现了35Ncm的最小插入扭矩，并立即进行假肢装载。基本模板允许在整个工作流程中维护固定引用，改善数字项目之间的过渡，外科手术,和假肢康复。
