The liquid for improving translucency for dental zirconia calcined body of the present disclosure contains a solvent and an indium compound, wherein a content of the indium compound based on the total amount of the liquid improving translucency for dental zirconia calcined body is within a range of 2.0 wt. % to 20.0 wt. % in terms of indium.

A method of correcting an axial position of a workpiece support (1) used for removing material from a dental workpiece (2) which is held by the workpiece support (1) and is rotated together with the workpiece support (1) about a drive rotation axis (3) when material is being removed. The workpiece support (1) has at least two workpiece support parts (4, 5, 6) which can be separated from each other and connected to each other. One of the workpiece support parts (4, 5) has at least one compensation region (7) with a material projection (8) for introducing a compensation surface (9) by removing material, and the other workpiece support part (6) has a seating surface (10) for connecting to the compensation surface (9) in a form fitting manner.

The invention relates to a dental prosthesis production device and method of manufacturing a dental prosthesis in which the dental prosthesis has an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) and on or to which abutment a dental structure (28) that is made of a dental material, in particular ceramic and/or plastic, and produced with the aid of a CAM process using rapid prototyping or compression molding technology can be secured. The abutment is mounted on the implant (40) via a releasable connection, in particular a screw connection (44), having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) is formed between the abutment (10) and the dental structure (28). A selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, in particular a milling cutter, or a CAM device is provided for shortening the abutment (10).

A dental stent for tooth restoration, includes an acrylic outer shell and a set of metal matrix separator strips partially embedded into an inner silicon bed. A method of manufacturing a dental stent includes 3D printing of a model wherein tooth forms of teeth to be restored are individually removable from a remainder of the model. A method of tooth restoration uses a dental stent, and a kit of parts including a dental stent and a composite resin, and optionally a heater, a light cure unit, and a finishing tool kit.

A dental model and related systems and methods, including a first component representing a portion of a patient's jaw and a second component that is demountably attachable to the first component, and a second component representing a dental structure of interest, such as the remaining portion of a tooth or a dental implant.

A set of artificial teeth for a denture comprises a maxillary unit and a mandibular unit. When set up in lingualised occlusion or balanced occlusion, at least one of following occurs: the palatal cusp (1a) of the maxillary posterior tooth (7a) fits into the distal fossa (1b) of the mandibular posterior tooth (8a); the palatal cusp (2a) of the maxillary posterior tooth (7b) fits into the distal fossa (2b) of the mandibular posterior tooth (8b); the mesial palatal cusp (3a) of the maxillary posterior tooth (7c) fits into the central fossa (3b) of the mandibular posterior tooth (8c); the distal palatal cusp (4a) of the maxillary posterior tooth (7c) fits onto the marginal ridge (4b) of the mandibular posterior tooth (8c); and the mesial palatal cusp (5a) of the maxillary posterior tooth (7d) fits into the central fossa (5b) of the mandibular posterior tooth (8d).

Provided are a matte reinforced zirconia abutment and a method for manufacturing the same wherein zirconia powder corresponding to the standard colors of a shade guide is used to provide the abutment with a quality similar to a natural tooth, while solving the problem a titanium abutment has had, that is, the difficulties in digital scanning because light is reflected by the gloss of the titanium abutment, and the whole machining method of the abutment is improved to greatly upgrade the durability of the abutment, and the method includes: a main material preparation step; a main material coloring step; a molded body producing step; a primary heat treatment step; a secondary heat treatment step; and a coupling hole formation step.

Dental devices and systems and methods for making the same are provided. In at least one embodiment, a computer readable medium containing instructions for fabricating an arch-shaped device for coupling to a patient's mouth is provided. The instructions can include using a denture form device to obtain an impression of a patient's mouth. The instructions can also include selecting an arch device and adapting that arch device to conform to a model of a patient's mouth, such that the adapted arch device may be used to ultimately form a denture.

A castable abutment that includes a fixing base provided with a through hole intended for placing a fixing screw of the castable abutment to the dental implant or to the dental implant analogue; a hollow tubular wall made of castable material and connected to the fixing base, including a hollow tubular joint made up of a succession of first and second asymmetrical frustoconical rings joined in succession forming an accordion section, made of a material and thickness selected to be elastically deformable, the geometry of which enables the tubular joint to be held in an inclined position.
