Dynamic navigation system-guided trans-inferior alveolar nerve implant placement in the atrophic posterior mandible: A case report

Figure 4 The navigation operation views are divided into dynamic and static views (Upper column is dynamic view, bottom columns are static views). Upper column: 2D dynamic view: slice maps of the implant drill location (axial, coronal and sagittal views); Bottom column left 1: 3D reconstruction graph: hard tissue model; Bottom column left 2: Distance graph of the drill tip deviates from the designed implant entry point; Bottom column right 2: Angle graph of the drill deviates from the designed implant axis; Bottom column right 1: Depth map of the drill tip in the designed implant direction, green indicates that it can continue drilling, yellow indicates vigilance, red indicates excess (tolerance value can be artificially set).
