Method for producing dental prosthesis, method for producing lithium disilicate blank for dental prosthesis and lithium disilicate blank for dental prosthesis
Provided is a method for quickly producing a dental prosthesis with a good accuracy. The method for producing a dental prosthesis including: a melting step of melting a material including no less than 60.0 mass % and no more than 80.0 mass % of SiO.sub.2, no less than 10.0 mass % and no more than 20.0 mass % of Li.sub.2O, and no less than 5.1 mass % and no more than 10.0 mass % of Al.sub.2O.sub.3; a glass blank production step of cooling to solidify the molten material to obtain a glass blank; a lithium disilicate blank production step of heating the glass blank to obtain a lithium disilicate blank whose main crystalline phase is lithium disilicate; and a processing step of processing the lithium disilicate by machining.
CEMENT SYSTEMS, HARDENED CEMENTS AND IMPLANTS
A cement system for forming an implant comprises a reactive glass ionomer cement (GIC) powder, a polycarboxylic acid or salt, and a filler. The polycarboxylic acid or salt is included to initially provide a paste having a pH less than 7 when the cement system is mixed with water. In one embodiment, the filler is substantially inert when mixed with water and is selected from (CaO)(AI.sub.2O.sub.3)6, (CaO)(AI.sub.2O.sub.3).sub.2, calcium silicate (CaOSiO.sub.2), and mixtures thereof. In another embodiment, the filler is substantially reactive when mixed with water and is selected from (CaO).sub.2(SiO.sub.2), (CaO).sub.3(SiO.sub.2), and mixtures thereof, and the cement system includes an additional acid to maintain the paste at a pH less than 7 for at least one hour after the cement system is mixed with water.
High strength and aesthetic lithium disilicate crystalline glass-ceramics containing cristobalite crystal and preparation method thereof
Provided is lithium disilicate crystalline glass containing cristobalite crystal phase for high strength and aesthetic traits and its manufacturing process thereof. Exemplary embodiments of the present invention provide the high strength and aesthetic lithium disilicate crystalline glass, one kind of dental restoration materials, and its manufacturing method which induces the growth of the different crystal phase, cristobalite, from glass with lithium disilicate crystal.
Lithium Silicate Glass Ceramic and Glass with ZrO2 Content
Lithium silicate glass ceramics and glasses are described which can advantageously be applied to zirconium oxide ceramics in particular by pressing-on in the viscous state and form a solid bond with these.
Hardenable Dental Compositions Comprising Basic Core Material Encapsulated in an Inorganic Shell and Dispensing Devices Therewith
A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g. sealant) composition for application to a tooth structure.
