The method comprises obtaining, by a controller of an automated surgical hub system, first image data of a surgical site, controlling, by the controller, at least one illumination source to illuminate a visible surface of the surgical site in a first manner by projecting structured light onto the visible surface, obtaining, by the controller, second image data of the visible surface of the surgical site under illumination in the first manner by the at least one illumination source, calculating, by the controller, a three-dimensional model of the visible surface based on the second image data obtained by the controller, and integrating, by the controller, the three-dimensional model of the visible surface with the first image data of the surgical site. The second image data is based on sensing the structured light projected onto the visible surface.

Methods and systems are described that receive intraoral scan data in response to an optical scan of a surface of the tooth and a material disposed between the tooth and a gingiva surrounding the tooth, the material separating the surrounding gingiva from the tooth and covering a sub-gingival surface of the tooth. The received intraoral scan data is processed to differentiate the first optical scan data associated with the sub-gingival surface of the tooth and the second optical scan data associated with the material covering the sub-gingival surface of the tooth. The three-dimensional model of the tooth is generated based on the first optical scan data that is associated with the sub-gingival surface of the tooth and the third optical scan data associated with the tooth surface that is not covered by the material such that the three-dimensional model of the tooth includes the sub-gingival surface of the tooth.

A system and method for enhanced surgical navigation and graphical user interfaces associated therewith. The system includes a 3D endoscope and a computing device including a display for displaying the graphical user interfaces. The 3D endoscope includes a camera source and a scan source and is utilized to generate a 3D spatial map of a surgical site. A position of a surgical tool is detected in the 3D spatial map, a distance between the position of the surgical tool in the 3D spatial map and a location of an anatomy is detected, and a warning is generated when it is determined that the distance between the position of the surgical tool in the 3D spatial map and the location of the anatomy is equal to or not greater than a threshold minimum distance.

A surgical system for use in a surgical procedure is disclosed. The surgical system includes at least one imaging device and a control circuit configured to identify an anatomical organ targeted by the surgical procedure, generate a virtual three-dimensional (3D) construct of at least a portion of the anatomical organ based on visualization data from the at least one imaging device, identify anatomical structures relevant to the surgical procedure from the visualization data from the at least one imaging device, couple the anatomical structures to the virtual 3D construct, and overlay onto the virtual 3D construct a layout plan of the surgical procedure determined based on the anatomical structures.
