A Splint-to-CT Data Registration Strategy for Maxillary Navigation Surgery

Figure 6

Marker-based pair-point registration using the custom-made splint, which is integrated with the reference frame and registration markers. The reference frame (white arrowhead) is fixed to the connector of the splint. The numbered landmarks (the 11 gutta-percha markers) are indicated within the optical tracking range of the navigation system and registered point-by-point in succession, using the pointer (black arrow).
