A method for intraoral imaging generates one or more output imaging signals from an intraoral probe and acquires multimodal image content from intraoral surface locations according to tissue response from the one or more imaging signals and associates spatial coordinates to the acquired multimodal image content. A surface contour of the patient dentition is generated by stitching the acquired multimodal image content and preserving the association of spatial coordinates with the stitched multimodal image content. Tooth outlines for one or more teeth are generated from the generated surface contour and the generated outlines arranged as a dental chart representing a spatial ordering of the one or more teeth and of supporting gum tissue adjacent to the teeth. The dental chart is populated by analyzing the acquired multimodal image content and associating the analysis to positions on the dental chart according to the preserved association of spatial coordinates and is displayed.

At least one embodiment of an ultrasonic periodontal probe, the ultrasonic periodontal probe comprising a grip portion having a longitudinal axis, a support member comprising a part having a longitudinal axis different from the longitudinal axis of the grip portion, and an ultrasonic device fastened to the grip portion via the support member, wherein the ultrasonic device is configured for emitting ultrasound signals within at least two emitting cones and for receiving corresponding echoed ultrasound signals, the at least two emitting cones extending in opposite directions with regard to a plane comprising the longitudinal axis of the grip portion.

An intraoral imaging apparatus for tomosynthesis imaging has an x-ray source having a primary collimator that defines boundaries of a radiation field. A transport apparatus translates the x ray source along a path for tomographic imaging. An intraoral x-ray detector defines an imaging area for the radiation field. A positioning apparatus correlates the position of the intraoral detector to the position of a secondary collimator. One or more radio-opaque markers provided on a detector attachment is coupled to the detector, the one or more markers configured to condition acquired x-ray images to relate the spatial position of the intraoral x-ray detector to the x-ray source position, wherein the one or more markers are disposed within the defined imaging area. A control logic processor accepts image data from the detector and determines the relative location of the source with respect to the detector according to detected marker position.

A method for imaging a tooth surface, the method executed at least in part on a computer, directs an excitation signal toward the tooth from a scan head and obtains a depth-resolved response signal emanating from the tooth, wherein the response signal encodes tooth surface structure information. Liquid and tooth surfaces are segmented from the depth-resolved response signal. The tooth surface structure information is adjusted based on the segmented liquid. A 3D image of the tooth is reconstructed according to the depth-resolved response signal and the adjusted tooth surface structure information. The 3D image content is displayed, stored, or transmitted.

Intraoral 3D scanner with fluid segmentation

An intraoral scanning apparatus has a source of low coherence light. An interferometer directs the low coherence light to a reference path and a sample path and generates image data according to interference from combined light returned along the reference and sample paths. A fixture is optically coupled to the sample path and has a bite portion featured for clamping between the jaws of a patient, a track that defines a curved scan path for scanning, one or more scanners configured to direct the sample path light to and from the teeth, and an actuator and translation apparatus that urges the one or more scanners along the curved scan path. A control logic processor synchronizes light scanning and acquisition from the fixture. A display is in signal communication with the control logic processor for display of acquired scan data.

Automatic intraoral 3D scanner with low coherence ranging

A method or computer program for forming a digital model of a patient's teeth. The method includes the steps of: obtaining a plurality of projection images acquired by scanning a negative impression of the patient's teeth using a computed tomographic imaging apparatus; generating, from the plurality of projection images, an air volume model of the air that surrounds the negative impression; defining a transition surface along edges of the air volume model that touch the negative impression; forming the digital model of the patient's teeth according to the defined transition surface; and displaying, storing, or transmitting at least a portion of the digital model of the teeth.

An intraoral camera comprising: an imaging section for obtaining image data from a patient in a dental chair; a transmitter comprising a transmitter configured for both wired and wireless transmission of the obtained image data to a computer; and a power section including a cable that obtains power from the dental chair or a battery module within the camera.

A method for obtaining an intraoral x-ray image determines an initial spatial position and angular orientation of an x-ray source relative to a detector. A first x-ray image is obtained with the x-ray source at the initial spatial position and angular orientation and stored, associating the initial spatial position and angular orientation to the first x-ray image. A sequence repeats that calculates a next spatial position and angular orientation for the x-ray source, provides positional adjustment information between the x-ray source and detector for obtaining a next x-ray image, measures and records the actual spatial position and angular orientation of the x-ray source relative to the detector and obtains and stores the next x-ray image at the measured spatial position and angular orientation, and forms a composite image using image data from the first and from the one or more next x-ray images.

Method for generating an intraoral volume image

A method for generating an electronic dental chart for a patient, executed at least in part by a host processor, obtains image data for each of a number of teeth of the patient and generates a template dental chart for the patient that represents the position of each imaged tooth with a symbol according to the obtained image data. The template dental chart for each imaged tooth symbol is populated to form the electronic dental chart by associating the obtained image data to the corresponding symbol in the template dental chart for the imaged tooth, analyzing the obtained image data to identify a condition of the imaged tooth, associating at least the identified condition with the symbol for the imaged tooth, and displaying the populated electronic dental chart, wherein the displayed electronic dental chart provides a visual indication of the identified condition.
