A computer system implements a neural network to process raw dental images to detect and number teeth and to diagnose pathological, non-pathological, and post-treatment conditions. Detected teeth, corresponding numbers, and any corresponding detected conditions are correlated to the dental image and presented in a graphical user interface comprising the image and a standard, symbolic dental chart associating the tooth number, detected conditions, and regions of the image to teeth represented in the symbolic chart.

Systems and methods for analyzing dental radiographs use deep neural network architectures, model training procedures and data processing method for automated dental charting and condition detection. The systems and methods produce detailed outputs that are comprehensive analyses of dental radiographs attributing detected conditions to particular teeth.

An attachment member for mating with a dental implant includes a non-rotational structure and a body. The non-rotational structure is configured to mate with a corresponding non-rotational feature of the dental implant. The body extends from the non-rotational structure. The body has (i) an exterior side surface configured to at least partially engage gingival tissue adjacent to the dental implant, (ii) an exterior top surface that is exposed through the gingival tissue, (iii) a screw access bore for receiving a screw that attaches the attachment member to the dental implant in a removable fashion, and (iv) a set of radiopaque information markers that is located internal to the exterior side surface and the exterior top surface. The set of radiopaque information markers indicates information regarding the dental implant that is revealed in response to a scan from a computerized tomography (CT) scanner.

Disclosed embodiments integrate a camera into an intraoral mirror. Integrating a camera into an intraoral mirror provides an efficient way to record and display what is visible to the healthcare provider in the mirror.

A cradle, assembly, system, and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.

A digital dental x-ray sensor device includes a rounded, three dimensional housing that lacks corners, edges, or other relatively sharp features that are known to cause discomfort when used in a patient's mouth. The rounded housing can be spherical, ellipsoid, or any similar regular or irregular rounded shape, and can be formed by ensuring that all curves of the surface of the rounded housing have a minimum radius that is sufficient to prevent features that can dig into the soft tissue of the inside of a patient's mouth.

When X-ray CT imaging is performed with a part located close to a front of a head as the imaging region, using the turning mechanism and the distance changing mechanism, the turning controller causes the X-ray generator and the X-ray detector to turn around the head while locating the imaging region therebetween, and causes the X-ray detector to turn along a go-around orbit, in which the X-ray detector comes close to the imaging region with respect to a front side of the head and moves away from the imaging region with respect to a rear side, by changing a distance between the X-ray detector and the center of the imaging region.

A method of taking a scan of a patient's oral cavity may include providing an anatomical healing cap that can be received within a subgingival void of a given tooth position. The method may also include taking a first scan (e.g., an extraoral scan) of the anatomical healing cap before seating the anatomical healing cap into the subgingival void of the given tooth position, where the anatomical healing cap is coupled to an implant disposed adjacent the anatomical healing cap. Further, the method can involve taking a second scan (e.g., an intraoral scan) of the anatomical healing cap and surrounding surfaces, and then integrating the two scans into an overall oral cavity scan. Reference points from the first scan may be used to align the second scan with the first scan, integrating the two together.

A face scanning and positioning structure used for a full denture includes an irregularly shaped body, development projections, and concave portions. The irregularly shaped body defines an asymmetrical face portion along an X-axis, an asymmetrical side portion along a Y-axis, and a thickness along a Z-axis. The development projections are arranged on the asymmetrical face portion and the asymmetrical side portion at predetermined positions. The development projections protrude outwardly. The concave portions are arranged on the asymmetrical face portion and the asymmetrical side portion at predetermined positions. The concave portions each have a concave shape. Through the development projections and the concave portions, the irregularly shaped body is in the form of an asymmetrical structure along the X-axis, the Y-axis, and the Z-axis. Through the irregular protrusions and concave portions, the face scanning and positioning structure can effectively reduce the image overlay error of a specific axis.

The present invention relates to a panoramic X-ray imaging apparatus capable of obtaining more accurate panoramic X-ray images while minimizing the rotation of a rotation arm, the panoramic X-ray imaging apparatus includes at least one X-ray source configured to irradiate X-rays and an X-ray sensor configured to receive the X-rays, a rotating arm configured to position the X-ray sensor and the X-ray source to face each other, a driver configured to rotate the rotating arm about a rotating shaft, a guide configured to provide directions for moving the X-ray sensor or the X-ray source, and wherein the at least one X-ray source is of an electric field emission type adopting an emitter of a nanostructure material and the X-ray source or the X-ray sensor is relatively movable along the guide in conjunction with a movement of the rotating arm.
