VERFAHREN ZUR HERSTELLUNG EINES ROHLINGS FÜR DENTALE RESTAURATIONEN MITTELS MEHRSTUFIGEM SEDIMENTATIONSVERFAHREN
The present invention relates to a process for producing a color-graded blank for dental restorations by way of a sedimentation process, to a blank obtained by the process according to the invention and to the use of a suspension for producing a color-graded dental restoration. The method comprises: a) providing a suspension comprising i) a liquid dispersant and ii) a base material and iii) one or more coloring substances; b) partial sedimentation with the formation of a sediment having a color gradient and a suspension supernatant; c) optionally completely or partially removing the suspension supernatant; d) adding a suspension comprising coloring substances, which suspension differs from the suspension in step a); e) sedimentation or partial sedimentation with the formation of a sediment having a color gradient and a suspension supernatant; f) optionally repeating steps c) and d) or step d) one or more times; g) solidifying the sediment with the formation of a color-graded blank.
