A dental implant device in the form of an interface member for forming an individually customized dental implant abutment mounted on a connection platform of a dental implant anchor adapted to be implanted, the interface member is a hollow tubular member featuring an internal lumen defined between a non-customizable distal portion and a customizable proximal portion.

A method for defining at least one boundary surface inside an artificial tooth element, the method comprising the steps of: aligning the tooth element with a coordinate system which preferably relates to anatomically defined directional terms; defining a first boundary curve on the tooth surface; determining a tooth surface located incisally/occlusally with respect to the first boundary curve; and moving this tooth surface inwards in the direction of the surface normal by different amounts in order to produce the at least one boundary surface, in particular the first boundary surface, wherein the different amounts of the movement involve variable design parameters.

A device comprising an orthodontic or dental appliance for use with a system for information management in dentistry, a system for storing and managing dentistry data such as information about an orthodontic or dental treatment of a person using a private network and a method for information management in dentistry are described.

Proposed is a method of forming, by utilizing a computer, an implant shape for minimizing stress to be applied to an implant, and a method of and an apparatus for recommending an optimal occlusal adjustment region for an implant by utilizing a computer. The method and apparatus also serve the purpose of adjusting force acting on an occlusal adjustment surface of an implant crown in such a manner that a direction of the force is closest to an implanted direction of an implant and of minimizing stress applied to the implant. In the method and apparatus, by utilizing a computer program, an occlusal adjustment surface between an arbitrarily selected crown on a position of a missing tooth and an antagonist tooth is extracted, and then an angle that an external force vector applied by the antagonist tooth to each local portion makes to the implant is minimized.

A holding surface is formed by an inclined surface formed from the upper edge of a flange of a disk-shaped processing block to a workpiece portion. The processing block is accommodated in an annular holding member, a pressing-side holding member is advanced with respect to an accommodating side holding member, and the facing peripheral edge of the pressing side holding member is brought into contact with the holding surface. Since the facing peripheral edge abuts on a circle centered around the axis of the holding surface formed by a conical side surface, the axis of the annular holding member and the axis of the processing block coincide with each other in a processing apparatus, and the processing block is set at a predetermined position

In a functionalization method for use in dentistry, and a method for same, the application device includes a support for receiving a partially processed shaped dental part for producing a dental restoration, and a dispensing device for the at least partial infiltration of a functionalization material onto the surface of the shaped dental part.

The invention relates to a method for constructing a restoration, in which a dental situation is measured by means of a dental camera and a 3D model of the dental situation is generated. In this case, a computer-assisted detection algorithm is applied to the 3D model of the dental situation, wherein a type of restoration and/or at least a tooth number and/or a position of the restoration to be inserted are automatically determined.

A deburr tool and processes to smooth spires on dentures after an adjustment by the dentist for a proper fit are presented. The deburr tool may have a deburr element comprised of soapstone or chalk, and the deburr element may have a variety of geometric shapes. For example, it may be spherically shaped, parabolic shaped, triangular shaped, cylindrical shaped with and an outer face between a one side and an other side, or rectangular shaped. Appling the one or more outer faces, surfaces, or edges of soapstone to the spires and using a rotary or reciprocating motion, the spires may be smoothed to provide a comfortable fit. The deburr element may have a holding element with a distal end and an other end connected to the deburr element and configured to use in an individuals hand or may be configured to insert in a rotary or reciprocating machine.

A support is coupled to an appliance to decrease warpage. The support may comprise a plurality of extensions coupled to the appliance to decrease warpage. The extensions can be coupled to the appliance at one or more of many locations, such as on an occlusal surface, a wall, an edge or an interior of the appliance. In some embodiments, the extensions are coupled to walls of the appliance such as a buccal wall and a lingual wall, and the extensions can be coupled to the walls of the appliance near edges of the walls, such as gingivally facing edges of the walls that are oriented toward the gingiva when the appliance is worn.

A computer-implemented method and system of determining a material surface from a volumetric density file includes generating a density frequency distribution of a volumetric density file of a dental impression and determining an iso-value of density between air and a particular material in the density frequency distribution. A computer-implemented method and system of creating a digital model from a CT scan of a physical dental impression includes selecting an iso-value of density for a digital volumetric density file having one or more voxels, generating one or more digital surface points in virtual 3D space for each of one or more voxels, and selecting a subset of digital surface points from the one or more digital surface points. A computer-implemented method and system of optimizing a digital surface includes moving one or more digital surface points to satisfy a criteria of optimum digital surface selection.
