摘要:
A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including containing between 6.0 wt % or 7.5 wt % to 20 wt % of yttria (Y2O3). The green body has multiple different layers having a different chemical composition between adjacent layers. The green body has a pre-sintered translucency that is substantially the same across the multiple different layers, and subsequently has a post-sintered translucency and a post-sintered color intensity/chroma with an inverse relationship with the post-sintered translucency increasing in one direction across the multiple different layers and the post-sintered color intensity/chromes decreasing in the same direction across the multiple different layers. The green body can have a color component and a diameter of at least 90 mm and thickness of 10-25 mm.
