Abstract: Dental bulk blocks for cutting machining are provided. The dental bulk block is a glass ceramic block having a structure in which crystalline phases including lithium disilicate as a main crystalline phase and lithium phosphate and at least one of cristobalite and tridymite as additional crystalline phases in an amorphous glass matrix. The dental bulk block is a functionally graded material (FGM) having gradations of size in the main crystalline phase along a depth direction thereof and having no interface at a gradation value change point at which a gradation value of size in the main crystalline phase changes. The dental bulk block is useful for the manufacture of artificial dental prostheses similar to natural teeth. Therefore, the present disclosure provides the effect of reducing the time and process of manufacturing artificial teeth protheses and increasing structural stability in teams of force distribution by functionally grading physical properties.

Abstract: A method includes determining depth values associated with a first set of pixel locations in a first image of a mouth. One or more function is generated for one or more color channels based on intensities of the one or more color channels at the first set of pixel locations and depth values associated with the first set of pixel locations. Image data comprising a new representation of the teeth is received, wherein the image data comprises a second set of pixel locations and new depth values associated with the second set of pixel locations. A new image is generated based on the image data and the one or more functions.

Abstract: [Object] To provide, for a composite resin (CR) having a wide range of applicable colors (shades) (wide-ranging color applicable CR), such as a CR having light diffusion properties and a CR that produces color by means of a structural color, a technology with which an excellent effect, specifically, an increased breadth (number) of applicable shades in comparison to an existing CR other than a wide-ranging color applicable CR, can be achieved.
[Solving Means] For example, in a demonstration instrument, a plurality of samples is prepared, a single wide-ranging color applicable CR has been used to restore a cavity in artificial teeth each having a different shade, the cavity being formed at a predetermined position of the artificial teeth, and the plurality of samples is disposed side by side and fixed on a display surface of a display plate, thereby making it possible to compare/contrast conditions of restored portions of the samples to each other and the color tone applicability thereof to those of a teeth to be restored.

Abstract: A dental instrument configured to measure a degree of tapering of a side wall of a tooth is described. The dental instrument may include a handle and a taper measuring component coupled to a distal end of the handle. The taper measuring component includes a first, second, and third elongated member. A bottom surface may be formed at a coupling point of the second and third elongated member, where the second elongated member is configured to be substantially vertical when the bottom surface is placed adjacent to a tooth, and the third elongated member projecting radially from the second elongated member at a predefined angle. The third elongated member is shaped and positioned to rest substantially flush along the at least one side wall of the tooth when a degree of tapering of the tooth is substantially similar to the angle, and may include a measuring component.

Abstract: An apparatus is an implant-dentist more readily identifiable visual segregation amongst their oral-surgery arbor-tools used conjunction with a conventional hand-held power/rotary-tool. The arbor-tools generally has at least a tri-echeloned set, wherein are included progressions of drill-bit lengths and companion thread-taps appearing in three different diameters. Additionally, the drill-bit shanks are optionally provided with a radial-flange serving as an automatic depth-stop device and these radial-flanges may include a distinctive annular-marker device serving to readily indicate the length of the selected drill-bit, thereby obviating usual procedure of stopping to confirm via the obscure conventional alpha-numeric indicia.
