Abstract (en)

[origin: WO2014033323A1] The present invention relates to a blank (10'), to a system and to a process for producing a dental restoration by subtractive machining. The blank (10') comprises a framework part (14') and a block part (12'), the framework part (14') comprising zirconium dioxide (ZrO2) and/or titanium and the block part (12') comprising lithium metasilicate or a glass-ceramic precursor. The block part (12') is connected to the outer side of the framework part (14') with a force fit. The framework part (14') has an inner contour (24') corresponding substantially to an outer contour of an implant base. A dental restoration produced from the blank (10') is suitable for connection to the implant base.
