Workflow for guided implant placement based on anatomic landmarks and the CAD-CAM fabrication of a prosthetic framework for an implant-supported fixed dental prosthesis

Digital workflows integrating computer-aided design and computer-aided manufacturing (CAD-CAM) have improved precision in implant-supported prostheses. This article describes a step-by-step technique for guided mandibular implant placement and the CAD-CAM fabrication of a patient-specific titanium bar based on cone beam computed tomography (CBCT) segmentation, anatomic reconstruction, and a functional digital waxing. The workflow combines prosthetically driven planning with anatomic reference alignment to enhance bar adaptation and prosthetic accuracy. The digital sequence allows clinicians and dental laboratory technicians to virtually design and verify the bar on a 3-dimensionally printed mandibular model before clinical application, minimizing chairside adjustments and improving interdisciplinary communication when providing complex complete arch implant-supported prostheses.
