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: Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve, that authenticate the sleeve for use with an intraoral scanning system. Authentication may include verifying that the sleeve is new (unused) and/or verifying that the sleeve is appropriate and/or intended for use with the intraoral scanning system. Once authenticated, operation parameters of the intraoral scanning system can be automatically set based on information from a scanned identifier on the sleeve.

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: An apparatus for dental confocal imaging comprises an illumination module for generating an array of light beams, an optics system for confocal focusing of the array of light beams and a probe head with a light-guiding part having an entrance face and an exit face. The illumination module, the optics system and the probe head are arranged such that the array of light beams from the illumination module 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, after having passed through the optics system, the outermost marginal rays of the outermost light beams with respect to the optical axis of the optics system are parallel or divergent to the optical axis.

Abstract: A dental articulator includes a first arm hingedly joined to a second arm about a pivot axis, where each one of the first arm and the second arm are configured to mount a dental model comprising at least one measurement element, and an inspection tool capable of checking the at least one measurable element against allowable tolerances. Each arm includes a mounting bracket having a distal portion adapted to mount the respective dental model and having a proximal portion. Each arm further has a base member having a distal portion adapted to hingedly join the first arm and the second arm about the pivot axis. The inspection tool comprises a first measurement device and a second measurement device. The first measurement device is coupled to the first arm or second arm and the second measurement device is coupled to the first arm or second arm.

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.
