Abstract
Official abstract text for this publication.
Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dental restoration having a biaxial strength of at least 250 MPa and a fracture toughness of at least 1.5 MPam 0.5 , wherein the dental restoration is produced from a lithium silicate dental glass-ceramic article comprising: lithium metasilicate as the main crystalline phase with 20-50 vol % lithium metasilicate crystalline phase. 2. The dental restoration of claim 1 , wherein the dental restoration is an inlay, an onlay, a bridge, an abutment, a facing, a veneer, a facet, a crown, a partial crown, a framework, or a coping.
