摘要： Disclosed is a pre-sintered ceramic block for a dental restoration, which has a low pre-sintering temperature, contains a silica main crystal phase, but does not contain or contains a small amount of lithium metasilicate crystal phase. The pre-sintered ceramic block has a low hardness, with a Vickers hardness of 0.5-3 GPa, which is significantly lower than that of a ceramic block containing a lithium metasilicate crystal phase, and same is suitable for dry machining and also wet machining when being machined into a dental restoration.

摘要： A pre-sintered porcelain block for dental restoration; the pre-sintered porcelain block does not contain crystal phases and has a Vickers hardness of 0.5-2 GPa. Due to a hardness which is significantly lower than that of the porcelain block containing a lithium metasilicate crystal phase, the pre-sintered porcelain block may be processed by using dry machining and can simultaneously be processed by using wet machining when being mechanically processed into a dental restoration shape.

摘要： A coloring solution for dental zirconia ceramics and a method for using the same are provided. The coloring solution consists of coloring agents, a solvent, and an additive. The coloring agents are a combination of two or more rare earth metal compounds, wherein the rare earth metal compounds having rare earth metal ions selected from the group consisting of praseodymium (Pr) ions, erbium (Er) ions, cerium (Ce) ions, and neodymium (Nd) ions. The concentration of the rare earth metal ions in the solution is 0.05˜3 mol/liter solvent. The molar ratio of Pr ions:Er ions:Ce ions:Nd ions in the solution is 1:(10˜50):(0˜20):(0˜30).
