Delivered by Dr. Ahmad Al-Hassiny, a renowned digital dentistry expert, this session begins with a brief narration of his professional transition from clinical practice to digital innovation.The core of the lecture delves into the technical intricacies of full-arch implant dentistry, specifically addressing the “All-on-X” workflow. Dr. Al-Hassiny provides a historical perspective, tracing the industry’s shift from traditional impression materials and intraoral welding to photogrammetry, and finally to modern intraoral scanning. He critiques the limitations of early methods, such as the high cost and bulkiness of photogrammetry devices, and explains the inherent inaccuracies of standard scanning due to “stitching” errors across edentulous arches.The lecture then focuses on the solution: horizontal scan bodies, specifically the DirectIP solution by Alliedstar. Then the course goes on to detail the workflow, explaining how the scanbodies allow for digital verification and alignment within a single scan, eliminating the need for complex verification jigs. Dr. Al-Hassiny emphasizes the critical importance of a “passive fit” (within 100 microns) for long-term success and explains the software processes that convert horizontal scan data into usable vertical abutment libraries for labs. The lecture will serve as a practical guide for clinicians and technicians, advocating for integrated software solutions to simplify complex full-arch rehabilitation.
