Abstract: A method of making a customized dental blank. The method has steps of obtaining from a dental practitioner a first color scheme and a different second color scheme as well as a first dimensional information for the first color scheme and a different second dimensional information for the second color scheme. The first and second dimensional information each relate to a size and/or a location within dimensions of the dental blank. The method further has the step of manufacturing the customized dental blank which has a first portion based on the first dimensional information according to the first color scheme and a second portion based on the second dimensional information according to the second color. Further the method has the step of providing the dental practitioner with the customized dental blank. The method helps facilitating the making of a dental restoration from a blank.

Abstract: A method of building up a dental object includes steps of (i) determining the three-dimensional shape of the object; (ii) mixing at least a first and a second component to form a hardenable composition; (iii) depositing the hardenable composition through a nozzle; (iv) performing steps (ii) and (iii) in combination with moving the nozzle by computer control based on said data. The invention helps providing an object like a dental restoration at maximized geometric and optical quality.

Abstract: A method of making a dental restoration has the steps of capturing an image of a tooth, posterizing the image, determining a tooth color structure, providing information about a multicolored block having a block color structure, matching the tooth color structure and the block color structure, based on the matching, determining a position within the block in which the tooth color structure and the block color structure match, and machining the dental restoration from the block at the determined position. The invention helps facilitating the making of dental restorations at maximized aesthetics.

Abstract: Dental articles and methods of using same. The dental article (510) includes a shell defining a volume, the shell (512) comprising a circumferential base (514) and an incisal/occlusal region (516) distal from the circumferential base. The dental article (510) further includes a hardenable dental composition (518) located within the volume, and an isolation film (520) located at the circumferential base of the shell.

Abstract: A system having at least one dental blank and an associated shade guide. The dental blank exhibits a non-uniform color shading, and the shade guide comprises a plurality of shade specimens each exhibiting a particular color shading representing the same color shading present in a partial area within the dental blank. A method of making a dental restoration includes the use of the system. The invention facilitates making a dental restoration having a color shading resembling the color shading of a natural tooth.
