A system assembly interface between a multi-part superstructure carrier, which carries a superstructure, and an implant body, which has an internal thread, is disclosed. A part of the superstructure carrier is arranged on the implant body via an implant screw bolt. The superstructure carrier comprises a superstructure main carrier and an attachment carrier that is detachably screwed to it. The system assembly interface ensures secure support of the superstructure with simple pre-assembly and final assembly. In the case of a plurality of implant bodies carrying a partial or total prosthesis, no appreciable stresses occur despite static overdetermination.

The present disclosure provides a denture bearing mechanism, a denture three-dimensional scanner and a control method thereof. The denture bearing mechanism includes a fixed seat, a bearing table and a driving assembly, where the fixed seat is detachably mounted on a storage table of the denture three-dimensional scanner; the bearing table is arranged on the fixed seat and connected to the driving assemblies; the driving assemblies are used for driving the bearing table to move relative to the fixed seat; and at least two scanning stations for placement of denture models are provided on the bearing table, so that the scanning stations can be mutually switched over in a motion state.

Method and prosthetic system for producing a substitution bridge structure with prosthetic teeth (6), for replacing an existing bridge structure (2) which is mounted on a base structure (1), wherein the base structure (1) is fixed to implants (10) by means of base screws (11) and the head (15) of the base screws (11) has a screw hole. A scan body is fixed to the head (15) of the base screws (11) and an intraoral scan of the oral cavity is executed and the scan data is related to a 3D digital model of the base structure (1) and/or of the existing bridge structure (2), wherein subsequently a 3D digital model of said substitution bridge structure is designed.

Provided is a data processing method according to the present disclosure including: a scan data acquiring operation of acquiring scan data expressing an object, a reliability determining operation of determining a reliability of at least one evaluation area including at least one unit area for evaluating the scan data, and an indicating operation of indicating the evaluation area as a predetermined mark depending on the reliability of the evaluation area.

A method of making an all-zirconium one-piece dental implant has: oral scanning after implantation of artificial tooth roots, 3D archiving, making temporary dentures, and making integrated permanent dentures. The oral scanning is executed by an optical scanner and generates a digital file of a denture model, a five-axis processing machine makes a temporary denture according to the digital file of the denture model to provide fitting information to modify the digital file of the denture model or make a permanent denture. Making the permanent denture with an all-zirconium material without metal support comprises the five-axis processing machine forming a through hole in the permanent denture.

A bite registration device including a scan post configured to attach to a dental implant, a bite pillar configured to be attached at a coronal end of the scan post, and a mechanism for attaching the bite pillar to the scan post, wherein the mechanism enables adjustment of a distance from a coronal end of the bite pillar to an apical end of the scan post. A bite pillar including a wide coronal end and an elongate shape configured to attach to an object in a mouth of a patient. A scan post including a screw thread for attaching a bite pillar thereto. A reference pillar configured as an elongate shape to be attached at a first end to an object in a mouth of a patient. Related apparatus and methods are also described.

The present disclosure provides methods, computing device readable medium, devices, and systems that utilize a cheek retractor and/or a mobile device holder for case assessment and/or dental treatments. One cheek retractor includes a first and a second lip holder, both including imaging markers of a predetermined size to determine a scale of teeth of a user, where each imaging marker is located a predefined distance from the remaining imaging markers, and where the lip holder is to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can include elements to receive a mobile device to capture images of the patient's teeth.

Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve.

Method and apparatus embodiments can generate a volume fluorescence image of a tooth. Method and apparatus embodiments can project structured light patterns onto a tooth and generate a contour (volume) image of the tooth surface from acquired corresponding structured light projection images; then acquire one or more fluorescence images of the tooth generated under blue-UV illumination. A composite image that shows fluorescence image content mapped to the generated contour image can be transmitted, stored, modified and/or displayed.

A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.
