Abstract: The invention relates to a computer program for specifying a material color of a dental restoration for which the desired tooth color is entered as a target tooth color (56) by the user, said target tooth color being the tooth color of a neighboring tooth, wherein upon specification of the material color of the dental restoration starting from the target tooth color (56) the material color of the dental restoration material is changed based on parameters such as the color of a stump and/or an abutment, the layer thickness of the dental restoration, the type of the dental restoration as well as the processing technique, wherein the specification of the material color of the dental restoration is controlled by the computer program, and wherein, once a parameter is selected, the next parameter is offered automatically, wherein the selection is limited based on parameters which are dependent on one another, such as the layer thickness, the restoration type, that is to say the indication, and the material.

Abstract: A partial dental arch is provided with dentin material and with cutting material and a boundary area therebetween. It includes a primary-position tooth region and additional tooth regions which are arranged more distally. A wavy structure of the boundary area is provided whose amplitude—when viewed in the distal direction—decreases in at least one section of the mesial-distal and/or occlusal-gingival extension, in particular with regard to the occlusal-gingival direction.

Abstract: Monochromatic dental shaped body, which has an opacity of from 70 to 78%, and a process for its production.

Abstract: The invention relates to a method (100) for producing color elements of a shade guide. To this end, color values of known color elements (15) of shade guides (10) with similar lightness values, hues and chromata are initially ascertained. In another method step, the color values of each new color element are determined while increasing a color distance (16) between the lightness values, hues and chromata of the previously ascertained color values.

Abstract: The invention relates to compositions based on ZrO2, and single- and multi-coloured blanks made from oxide ceramics, and a process for their preparation, in which a) oxide ceramic powder is coated with a colouring substance, b) the coated powders are preferably graded and at least one coloured powder is filled into a compression mould, c) the coloured powder or powders are compressed to produce a shaped body, and d) the compressed shaped body is sintered to produce a blank, and to the use of these blanks for the preparation of dental restorations.

Abstract: A tooth shade scan system is provided that identifies tooth shades for a patient's tooth. An electronic database of tooth shade information for a shade guide may be stored. The database may include shade information based on tooth regions (e.g., the incisal, central, and cervical). A system operator may be shown an image of a patient's tooth on display equipment such as a computer monitor. An application running on the system may display dividers that the operator can manipulate to divide the image of the patient's tooth into regions. The regions may correspond to regions for which specific tooth shade information is available in the database. Values representative of a limited number of color characteristics for a region as a whole may be determined from the image. Corresponding categories of color characteristics may exist in the database, which is then used to identify tooth shades by region for the patient's tooth.
