Dental Implant Navigation Calibration Using Visual Markers

The patent introduces artificial marker points as intermediary objects that are placed on the patient's jawbone surface. These marker points serve as a mediator between the anatomical structures and the navigation system, enabling precise registration without requiring direct implantation into the bone. The marker points create a clear, detectable reference framework that improves registration precision while maintaining procedural simplicity.

The patent creates a virtual copy of the patient's jawbone anatomy through 3D reconstruction from CT scans. This digital model is then registered with the physical jawbone using marker points, allowing the navigation system to track positions accurately in the virtual space that corresponds to the physical surgical field, thereby improving registration precision.

The patent uses marker points that are placed on the surface of the jawbone rather than being implanted deep into the bone structure. This partial action approach provides sufficient registration precision for navigation while avoiding the excessive trauma and infection risks associated with deep implantation. The marker points remain on the accessible surface, minimizing invasive procedures.

The patent employs disposable marker points that are placed temporarily during the surgical procedure. These marker points serve their registration function and then can be removed or discarded, avoiding the need for permanent implants. This reduces patient trauma and eliminates long-term infection risks while maintaining high registration precision during the critical surgical phase.
