    Abstract: An apparatus for dental imaging comprises a light source for generating light, an optics system for focusing the light, and a light-guiding part having an entrance face and an exit face. The light source, the optics system and the light-guiding part are arranged such that the light passes through the optics system, enters the light-guiding part via the entrance face, and exits the light-guiding part via the exit face. The optics system is configured such that, upon entering the light-guiding part, an outermost chief ray of the light with respect to an optical axis of the optics system is divergent to the optical axis and an outermost marginal ray of the light with respect to the optical axis is parallel or divergent to the optical axis.

    IPC: A61C9/00

    Abstract: An intraoral scanner includes a probe housing disposed at a distal end of an elongate wand. The intraoral scanner further includes a window structure coupled to the probe housing. The window structure and the probe housing form an interior volume. The window structure has a concave transverse cross section. The intraoral scanner further includes optical components disposed within the interior volume. The optical components include a first camera having a first orientation and a second camera having a second orientation that is different than the first orientation. The first camera and the second camera are to capture images of dental sites.

    Abstract: A method comprises receiving a digital file comprising a design model representative of an upper human jaw or a lower human jaw and generating at least one measurement element on the design model. The method further comprises updating the digital file comprising the design model with the at least one measurement element, wherein the digital file comprises a set of instructions to be executed by a three-dimensional (3D) printer to fabricate a dental model with the at least one measurement element based on the design model, wherein the at least one measurement element is measurable to perform a quality assessment of the dental model.

    Abstract: An intraoral scanner comprises one or more structured light projectors and two or more cameras, where each structured light projector projects a pattern of light onto an intraoral three-dimensional (3D) surface and the two or more cameras capture one or more sets of images, wherein each image includes at least a portion of the projected pattern of light. A processor solves a correspondence problem within a set of images of the one or more sets of images such that points in 3D space are determined based on correspondence of captured features in the set of images to projected features of at least the portion of the projected pattern, wherein said points in 3D space form a solution to the correspondence problem. The processor calibrates the intraoral scanner by performing an adjustment to stored calibration data associated with the intraoral scanner based on the solution to the correspondence problem.

    Abstract: An intraoral scanning device comprises housing comprising a head configured for insertion into a patient oral cavity, the head comprising a sloped surface and an aperture for transmission of optical signals, a transparent element positioned within the aperture, wherein the transparent element is at an acute angle with respect to the sloped surface, and a defogging unit comprising a heating unit. The intraoral scanning device further comprises a protective sleeve configured to cover at least a part of the head when the protective sleeve is coupled to the housing. The protective sleeve 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, and 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.
