Abstract: Removable barrier devices for covering an intraoral scanner. The barrier device includes a cover that is adapted to fit over a probe of the scanner. The cover includes a distal portion having walls defining an internal cavity for accommodating a distal end of the probe and formed of a first material, wherein at least one of the walls includes at least one window for allowing transmission of an optical signal between the probe and an external environment. The cover also includes a proximal portion coupled to the distal portion. The barrier device also includes a flexible sleeve adapted to cover a handle of the scanner, the flexible sleeve coupled to the proximal portion of the cover at an interface region configured to prevent fluid from passing through the barrier device between the cover and the sleeve.

Abstract: An apparatus for intraoral scanning comprises an elongate wand comprising a probe at a distal end of the wand, one or more cameras and a computer processor. The one or more cameras are disposed within the probe and arranged within the probe such that the one or more cameras receive rays of light from an intraoral cavity in a non-central manner, wherein the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity introduces image distortion. The computer processor is configured to generate a three-dimensional model of an intraoral surface based on images from the one or more cameras, wherein the computer processor compensates for the image distortion specifically introduced by the non-central manner in which the one or more cameras receive the rays of light from the intraoral cavity.

Abstract: A dental scanning system comprises an intraoral scanner and one or more processors. The intraoral scanner comprises one or more light projectors configured to project a pattern (comprising a plurality of pattern features) on a dental object, and two or more cameras configured to acquire sets of images, each comprising at least one image from each camera. The processor(s) are configured to determine a correspondence between pattern features in the pattern of light and image features in each set of images by determining intersections of projector rays corresponding to one or more of the plurality of pattern features and camera rays corresponding to the one or more image features in three-dimensional (3D) space based on calibration data that associates the camera rays corresponding to pixels on the camera sensor of each of the two or more cameras to the projector rays.

Abstract: An apparatus for measuring a surface topography of a patient's teeth may include an optical probe, a light source configured to generate incident light, and focusing optics configured to focus one or more wavelengths of the incident light to a fixed focal position external to the optical probe, wherein the fixed focal position is fixed relative to the optical probe. The apparatus may further include a light sensor configured to measure a characteristic of returned light generated by illuminating the patient's teeth with the incident light and a processing unit operable to determine the surface topography of the patient's teeth based on the measured characteristic of the returned light.

Abstract: Described herein are apparatuses for dental scanning and components of apparatuses for dental scanning. A component of a dental scanning apparatus may include a beam splitter, a transparency and an image sensor. The component may have a first surface and a second surface. The transparency may be affixed to the first surface of the beam splitter, and may comprise a spatial pattern disposed thereon and be configured to be illuminated by a light source of the dental scanning apparatus. The image sensor may be affixed to the second surface of the beam splitter, wherein as a result of the transparency being affixed to the first surface of the beam splitter and the image sensor being affixed to the second surface of the beam splitter, the image sensor maintains a stable relative position to the spatial pattern of the transparency.

Abstract: An apparatus for dental imaging comprises a light source for generating light, an optics system for focusing the light, and a probe head. The light source, the optics system and the probe head are arranged such that the light passes through the optics system, passes through the probe head, and exits the probe head. The optics system is configured such that chief rays of the light before entering the probe head are divergent to each other, wherein an angle defined by a marginal ray of an outermost beam of the light is complementary to an angle defined by an extreme off-axis chief ray of the light with respect to the optical axis.

Abstract: A non-transitory medium includes instructions for generating a three-dimensional virtual model of an intraoral object by receiving surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of an intraoral scanner, wherein the surface scan data comprises data for a plurality of points of the intraoral object, and adjusting the data for one or more of the plurality of points to compensate for one or more inaccuracies associated with changes of a shape of a focusing surface. A three-dimensional virtual model of the intraoral object is generated using the adjusted data.
