A method of forming an orthodontic aligner from an aligner digital model, the method comprising the steps of: three-dimensionally printing an intermediate structure comprising fused filaments from a biocompatible thermoplastic according to the aligner digital model via fused deposition modelling; coating the intermediate structure with a biocompatible translucent photopolymer; and irradiating the coating with ultraviolet light to cure the coating on the intermediate structure, thereby forming the orthodontic aligner.

The present invention relates to a method for additive manufacturing of a position sensitive colored ceramic article comprising: a) providing at least one flowable ceramic component; b) forming a green body by sequential deposition of the ceramic component provided in step a) and optionally a support material not intended to be part of the final article; c) position sensitive application of a coloring substance in a solvent to at least a part of the surface of the green body formed in step b), wherein the coloring substance is applied simultaneously to the sequential deposition; d) heat treatment or curing of at least a part of the green body surface obtained in step c); wherein the method steps a)-d) are at least performed once; e) optionally removing the support material from the green body; and f) sintering the green body to obtain the ceramic article; wherein the coloring substance is a dyestuff according to ISO 18451-1:2019(E). In addition, the present invention relates to a system adapted to perform the method and a control data set configured, when implemented in an additive manufacturing system, to cause the system to execute the steps of the inventive method.

A customized resorbable three-dimensional scaffold for oral and maxillofacial bone grafting involves merging two sets of three-dimensional information obtained from a patient, the first set includes three-dimensional bone information and the second set includes three-dimensional teeth and tissue information. The merged information is used to generate a three-dimensional shape of the bone to be regenerated, a three-dimensional position of the missing tooth/teeth, and a three-dimensional model of the customized resorbable three-dimensional scaffold for oral and maxillofacial bone grafting. The three-dimensional model is used to generate the customized resorbable three-dimensional scaffold and resorbable connectors for the customized resorbable three-dimensional scaffold.

The present invention relates to a system and method of manufacturing a mouth piece by 3D printing a 3D printer readable file encoding the mouth piece, the method comprising steps of: obtaining a scan file comprising physical data representing a user's teeth and gum line using 3D scanner means (100); removing outlier data from physical data in the scan file; generating representative geometrical data of the curvature of the user's teeth and gum line from the physical data; generating a virtual base model representing a mouth piece from the physical data and the representative geometrical data, the virtual base model having customisable dimensions (101); removing selected regions from the mouth piece represented by the virtual base model (102); and from the virtual base model, generating the 3D printer readable file encoding the mouth piece for printing on 3D printing means (103). The present invention provides a computer implemented development environment adapted with user interface means providing an operator with the ability to customise the mouth piece as required.

Systems, methods, and/or computer-readable media described herein provide technical solutions to the highly technical problems of machine generation of dental restorations. In particular, these systems, methods and/or computer readable media may provide technical solutions to aid in the creation of dental restorations that more closely resemble a natural tooth (including its internal optical structure). These systems, methods and/or computer readable media may help in virtually rendering a tooth, including its internal optical structure, and apply these renderings (e.g., digital models) to the fabrication of the dental restoration.

The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

The invention relates to a method for manufacturing a dental prosthetic assembly. The dental prosthetic assembly comprises a first and a second element. The first element comprises a first connection portion with a reception configured to establish a mechanical connection between the first and the second element by receiving a protrusion of a second connection portion comprised by the second element.

The invention relates to a computer-implemented method for adjusting a position of artificial teeth of a denture. A digital 3D model of the denture comprising at least a denture part is provided. The denture part is configured for a jaw of a patient and comprises a dental arch with a plurality of artificial teeth arranged in an artificial gingiva. A deformable gingiva section of the artificial gingiva is defined between the teeth of the plurality of artificial teeth and a fixed gingiva section of the artificial gingiva with a fixed geometrical form. The dental arch is moved as a whole relative to the fixed gingiva section in order to adjust the position of the dental arch. A geometrical form of the deformable gingiva section is deformed due to the moving of the dental arch, whereas the fixed gingiva section maintains the fixed geometrical form.
