Abstract: The present disclosure provides systems and computer implemented methods that include motion compensation in a three-dimensional (3D) scan. Motion compensation can include receiving 3D scans of a dentition, estimating a velocity of the 3D scanner during the 3D scan using a rigid body transformation based on input from a position tracking device in response to input from a 2D imager, and compensating for motion during the 3D scan based on the estimated velocity from the position tracking device.

Abstract: An intraoral scanning system comprises and intraoral scanner and a processor. The intraoral scanner comprises one or more cameras and one or more structured light projectors, the intraoral scanner to generate a series of images using the one or more cameras, each image including at least a portion of a pattern projected by the one or more structured light projectors onto an intraoral three-dimensional surface. The processor runs a correspondence algorithm to compute respective three-dimensional positions of a plurality of features of the pattern on the intraoral three-dimensional surface, as captured in the series of images. The processor identifies the computed three-dimensional position of a detected feature of the pattern as corresponding to a particular projector ray r, in at least a subset of the series of images. The processor tracks the particular projector ray r across one or more additional images of the series of images.

Abstract: An intraoral scanning device comprises a housing having a longitudinal axis and comprising a head configured for insertion into an oral cavity of a patient, the head comprising an aperture for transmission of optical signals, a transparent element positioned within the aperture, wherein the transparent element is non-orthogonal to the longitudinal axis, and a defogging unit comprising a heating unit. A protective sleeve is configured to cover at least a part of the head and comprises an additional aperture that aligns with the aperture and an additional transparent element in the additional aperture. A gap separates the additional transparent element from the transparent element when the protective sleeve is coupled to the housing. The housing and the protective sleeve are configured such that heat generated by the heating unit is transferred from the heating unit to the additional transparent element despite the gap that separates the additional transparent element from the transparent element.

Abstract: The present disclosure is directed to capturing a 3-dimensional representation of a patient's face from multiple angles to be integrated with (fused) with at least a 3-dimensional intra-oral mesh of the patient's teeth for purposes of visualizing a dental treatment plan. In one aspect, a method includes capturing media of a patient's face from multiple angles, using at least one device; transforming the media into a 3-dimensional representation of the patient's face; and transmitting, the 3-dimensional representation of the patient's face to one or more processing components to be integrated with a 3-dimensional representation of the patient's intra-oral scan to visualize a dental treatment plan for the patient.

Abstract: Methods for automatically segmenting a 3D model of a patient's teeth may include scanning a patient's dentition and converting the scan data into a 3D model, including a sparse voxel representation of the 3D model. Features can be extracted from the sparse voxel representation of the 3D model and input into a machine learning model to train the machine learning model to segment the 3D model into individual dental components.
