A computer-implemented method and system are provided for registering a human jaw with a volumetric computed tomography image of that jaw positioned in an image reference coordinate system and stored in a computer-readable memory. The method involves attaching a jaw marker to the jaw to establish a pose trackable jaw reference coordinate system; moving a surface sampling tool over at least one portion of the surface of the jaw while operating a pose tracking system and a computer processor to record samples in the jaw reference coordinate system indicative of locations within the at least one portion of the surface of the jaw; operating a computer processor to determine an approximate initial registration mapping; then beginning with the approximate initial registration mapping, incrementally adjust the registration mapping. Incrementally adjusting the registration mapping involves computing an edge proximity value at each sample location mapped to the image by the registration mapping.

According to the invention, a method and system are provided for scanning, and for facilitating scanning of, an intraoral cavity. The target parts of the intraoral cavity that it is desired to have scanned are identified, and the spatial s relationships between a scanning device and the target parts of the intraoral cavity suitable for enabling said target parts to be scanned by said scanning device, are also identified or otherwise determined. These relationships are then displayed, and the displayed relationships are used as a guide for scanning the intraoral cavity.

Apparatus for three-dimensionally measuring a row of teeth, having, on a shaft, an autonomously movable measuring head including a central measuring member and at least two lateral measuring members movably interconnected and defining a variable measurement space. The head, placed on a row of teeth, is guided therealong using guiding elements. Measuring units in the measuring members measure structures in the measurement space. Measurements are taken from multiple solid angle positions of the measuring units, the positions being preset in the measuring members, being adjusted by moving the measuring members, being taken by having mirrors move, in a controlled manner, the beam path generated by the measuring units, or being aligned by changing the angular position of the head relative to the shaft in an automatically controlled manner.

An automotive intraoral scanner applied in a mouth includes a biting piece, a track piece and at least one mobile image processing set. The biting piece is sandwiched between two rows of teeth. The track piece is installed in the biting piece and disposed corresponding to the rows of teeth, and a shape of the track piece is similar to a shape of the rows of teeth. The mobile image processing set is installed on the track piece and moved along the track piece, and the mobile image processing set is disposed corresponding to the rows of teeth. Therefore, the automotive intraoral scanner has advantages of easy operation.

There is provided according to some embodiments, a system, device and method for a three dimensional (3D) intraoral scanning of at least a portion of a tooth. An intraoral scanner may include a shadow casting object extending between a light emitter and the portion of the tooth. An imaging module may image the portion of the tooth and/or the projected shadow of the shadow casting object. A method to construct a 3D model may include illuminating at least a portion of the tooth with a light emitter; casting a shadow on the portion of the tooth by an object located between the emitter and the tooth; imaging the portion of the tooth, including at least a part of the shadow; and determining a location of a point on the tooth and related to the shadow, using the image.

A mobile device comprises a display, an image capture device that generates image data of a face of a viewer of the display, and a processing device. The processing device receives the image data and sends the image data to a computing device. The computing device processes the image data to identify a position of a dental arch in the image data; determines a treatment outcome for the dental arch; generates a post-treatment image of the dental arch that shows the treatment outcome; generates updated image data comprising a superimposition of the post-treatment image of the dental arch over the received image data; and sends the updated image data to the mobile device. The mobile device outputs the updated image data to the display, wherein the post-treatment image of the dental arch is superimposed over the dental arch in the received image data such that the post-treatment image is visible in the display rather than a true depiction of the dental arch.

A pressure sensor dental impression tray is provided and designed for both the maxilla and the mandible. The dental impression trays provide real-time feedback to prosthodontists regarding the force applied during the impression procedure and incorporate an array of pressure sensors and an analog to digital meter to measure and display the applied force in real-time.

The invention relates to a method for measuring a dental situation comprising a plurality of implants and/or preparations for inserting dental restorations. Using a first measuring method, a first region of the dental situation is initially recorded while first measurement data are generated. The first region is selected to comprise at least two implants and/or preparations. Subsequently, object regions surrounding the implants and/or the preparations are established, and, while using a second measuring method, the established object regions are detected, and second measurement data are generated. The second measuring method is more precise than the first measuring method.

A dental implant is provided. In some embodiments, the dental implant facilitates viewing an outside of a distal end of the dental implant via a proximal opening of the dental implant, and/or facilitates providing bone graft material via selectively closable one or more distal openings. A dental implant installation procedure is also provided in which a distal end of a dental implant is projected into a paranasal sinus cavity or a nasal cavity to displace the respective sinus membrane or nasal cavity membrane from the respective cavity floor, while minimizing risk of damaging the respective membrane. Bone graft material is introduced into the space created between the respective membrane and the respective cavity floor via a distal portion of the dental implant to form a desired sinus augmentation.

A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. An intra-oral scan is made of the patient's mouth having an installation site with a dental implant installed and a healing abutment attached to the dental implant. The healing abutment has at least one informational marker. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker and the three-dimensional model are used to manufacture a rapid prototype model of the patient's mouth, which includes a dental implant analog.
