Abstract: A method of making a dental restoration has the steps of: determining a virtual space available for accommodation of a dental restoration for a tooth to be restored; retrieving a predefined virtual master dental restoration surface from a database; fitting the virtual master dental restoration surface in the space to provide a virtual outer dental restoration surface; creating a virtual inner dental restoration surface independent of a shape of the tooth to be restored; providing a virtual model of a dental restoration based on a combination of the virtual outer dental restoration surface and the virtual inner dental restoration surface; and fabricating the dental restoration based on the dental restoration model.

Abstract: The present invention relates to a process for producing a ceramic article, the process comprising the steps of providing a printing sol, the printing sol comprising solvent, nano-sized particles, radiation curable monomer(s) and photoinitiator, the printing sol having a viscosity of less than 500 mPa*s at 23° C., processing the printing sol as construction material in an additive manufacturing process to obtain a 3-dim article being in a gel state, the 3-dim article having a Volume A, transferring the 3-dim article being in a gel state to a 3-dim article being in an aerogel state, heat treating the 3-dim article to obtain a sintered 3-dim ceramic article, the ceramic article having a Volume F, Volume A of the 3-dim article in a gel state being more than 500% of Volume F of the ceramic article in its sintered state. The invention also relates to a ceramic article obtainable according to such a process. The ceramic article can have the shape of a dental or orthodontic article.

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 dental coloring stamp has a transfer pad for transferring a dental coloring solution to a precursor of a dental restoration. The transfer pad is at least partially formed of an open-celled elastic sponge and has a free transfer surface. The cross-section of the transfer pad is greater than a circular area of 10 mm in diameter so that a side of a dental restoration precursor can be stamped and thus colored. The invention helps facilitating the coloring of dental restorations.
