The present invention relates to a dental blank, in particular a parallelepipedal block, having an upper surface and a lower surface, which is composed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least a portion of the surfaces of the blank.

COMPUTER IMPLEMENTED METHODS FOR DENTAL DESIGN

Computer implemented method of generating a dental design, comprising: a) capturing a facial image comprising a head of a patient and a smile; b) displaying it as a first image; c) capturing a 3D intraoral scan; d) aligning the 3D scan to the head; e) determining bounding boxes in the 3D scan, each comprising a single tooth; f) showing a view of the 3D scan and the bounding boxes as a second image; g) showing the bounding boxes as overlay on the first image; i) allowing the bounding boxes to be resized/repositioned; ii) defining a limited set of parameters to characterize the tooth inside the bounding box, and searching a number of candidate matching teeth from a 3D digital library of teeth, and proposing a candidate matching tooth; iii) overlaying the first image with a digital representation of the proposed candidate matching tooth from the digital library.

Fixation base and guides for dental prosthesis installation
11576755 · 2023-02-14 · ·

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

20230045664 · 2023-02-09 ·

A protective cap device for a milling blank, with a retaining element (24) or retaining extension (26) with which the milling blank (1) can be clamped, in particular in a clamping holder of a dental milling machine, and with a central channel (12) which extends over and/or passes through at least 70% of the length of the blank (1), is provided. The channel (12) terminates at or in the retaining element (24) or extension (26). A central pin (4) extends in the channel (12) and is either fixed or movably mounted in the channel (12), It is provided that a protective cap (10) covers an end face (20), which is opposite the retaining element (24) or retaining extension (26), of the milling blank (1).

METHOD AND SYSTEM FOR SUPPLEMENTING SCAN DATA BY USING LIBRARY DATA
20230043519 · 2023-02-09 · ·

A method for supplementing scan data by using library data according to the present invention comprises: a scan step of acquiring scan data of a subject including a structure; a step of selecting library model data corresponding to the structure; and a step of post-processing the scan data, wherein the library model data is added at the step of post-processing of the scan data and is post-processed together with the scan data. Accordingly, the scan data in which distortion or a data gap has occurred is supplemented by the library model data, and thus a user acquires a highly reliable three-dimensional model.
