The invention relates to a method for producing an artificial gingiva, in which a 3D model of the artificial gingiva is already provided. A gingiva template representing at least partial areas of the 3D model of the artificial gingiva is constructed as a negative mold using the 3D model of the artificial gingiva.

The present invention relates to a method for the design and manufacture of a dental component with a surface, wherein a 3D model of the dental component is designed by means of a CAD unit and the dental component is manufactured by a CAM unit on the basis of the 3D model. In order to provide a method which significantly shortens the time required for the design and manufacture of a dental component, so that the length of the dental session at which the patient must be present is shortened, it is inventively proposed that the 3D model is manufactured in at least one first design step, in which a first 3D submodel is designed with at least one first surface section, and a second design step in which a second 3D submodel is designed with at least one second surface section, wherein the first design step is completed before the second design step and the CAM unit begins the manufacture of the first surface section of the dental component based on the first 3D submodel before the design of the second 3D submodel is completed.

The invention relates to an additive method for producing a dental working model for an articulator, comprising the steps: additively producing a base plate for attachment to the articulator, and additively producing a dental model, wherein the base plate and the dental model are configured to be fixed to one another in a positionally secure manner. Another object of the invention is an additively produced dental working model for an articulator, comprising an additively produced base plate configured for attachment to the articulator, and an additively produced dental model, wherein the base plate and the dental model are configured to be fixed to one another in a positionally secure manner.

A manufacturing method for a dental object (100) including the steps of generating a dendritic base structure (101) on a build platform (103) and building the dental object (100) on the dendritic base structure (103) by a three-dimensional printing method.

The present invention relates to an apparatus and method for three-dimensionally laminating a ceramic denture in a color-and-transmittance variable manner. A base slurry and a light transmissive slurry are mixed at a ratio regulated by a main controller according to a slurry ratio parameter datum, and then a slurry mixture is laid on a substrate by a laying module to form a slurry layer; next, the slurry layer is photocured by a photocuring module according to a laminated graphic under control of the main controller; in such a manner, the slurry layers are laminated and cured one by one so that a denture green body is formed; finally, the denture green body is sintered at a high temperature to form a ceramic denture. The present invention allows each slurry layer to exhibit different color and transmittance, resulting in quite natural gradation of color and gradation of transmittance.

The methods disclosed herein of generating three-dimensional lattice structures and reducing stress shielding have applications including use in medical implants. One method of generating a three-dimensional lattice structure can be used to generate a structure lattice and/or a lattice scaffold to support bone or tissue growth. One method of reducing stress shielding includes generating a structural lattice to provide sole mechanical spacing across an area for desired bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. Some methods are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

A dental abutment system including an abutment, an inlay and screw, wherein the screw at least partially occupies the interior channel of the inlay. A method of manufacturing a dental abutment system and to a control data set including a plurality of control instructions that are configured to, when implemented in an additive manufacturing system, to cause the system to execute at least the step of forming an abutment at the distal end of an inlay using an additive manufacturing process. The screw is a captive screw. The interior channel of the abutment is variable in diameter and the smallest diameter is ≥102% and ≤110% of the width of the screw head and the longitudinal axis of the interior channel of the abutment and the longitudinal axis of the interior channel of the inlay are angled with respect to each other at an angle of ≥5 degrees.

A method for establishing a denture dentition model includes: obtaining face information and teeth alignment information of a use, to establish a three-dimensional mouth-opening face model and an original teeth model, and superimposing the original teeth model to the three-dimensional mouth-opening face model; establishing a reference line corresponding to each of the teeth of the original teeth model; generating a plurality of grids on the three-dimensional mouth-opening face model according to the reference lines, and adjusting each of the grids to correspond to the edge of each tooth, to obtain an actual size of each of the teeth; providing an upper edge curve and a lower edge curve on the three-dimensional mouth-opening face model as a smile curve; aligning each grid with the smile curve, and placing a denture model in each grid; and adjusting a denture contour of each denture model, to generate the denture dentition model.

An implant-supported denture placement and alignment system may include a denture apparatus. The denture apparatus may have a denture base and a denture base positioning system. The denture base may be connectable to implants. Moreover, the denture base positioning system may position the denture base in substantially the same position as a surgical guide used to place the implants. In this manner, the denture apparatus may be positioned so that it is mountable to the implants placed according to the surgical guide following their placement in a patient's mouth. In this manner, variations in the placement of the implants arising during the process of installing the implants may be compensated by transferring the actual implant positioning to the denture apparatus when it is positioned by the denture base positioning system.
