Provided are metal oxide ceramic materials and intermediate materials thereof (e.g., nanozirconia gels, nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental articles). The nanozirconia gels are formable gels. Also provided are methods of making and using the metal oxide materials and intermediate materials. The nanozirconia gels can be made using, for example, osmotic processing. The nanozirconia gels can be used to make nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental article. The nanozirconia green bodies, pre-sintered ceramic bodies, zirconia dental ceramic materials, and dental articles have desirable properties (e.g., optical properties and mechanical properties).

Metal oxide ceramic nanomaterials and methods of making and using same

Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools.

Lithium silicate materials

The invention relates to multi-layer oxide ceramic bodies and in particular to presintered multi-layer oxide ceramic blanks and oxide ceramic green bodies suitable for dental applications. These bodies can be thermally densified by further sintering without distortion and are thus particularly suitable for the manufacture of dental restorations. The invention also relates to a process for the manufacture of such multi-layer oxide ceramic bodies as well as to a process for the manufacture of dental restorations using the multi-layer oxide ceramic bodies.

Controlling of sintering kinetics of oxide ceramics

Zirconia dental ceramics exhibiting opalescence and having a grain size in the range of 10 nm to 300 nm, a density of at least 99.5% of theoretical density, a visible light transmittance at or higher than 45% at 560 nm, and a strength of at least 800 MPa.

Nanocrystalline zirconia and methods of processing thereof

A cluster mill blank includes a framework constructed to cooperate with a blank holder of an existing CAD/CAM system, and a plurality of sub-blanks attached to the framework forming an addressable matrix or cluster blank. CAD/CAM systems including such a framework, as well as associated methods are described.

Addressable matrices/cluster blanks for dental CAD/CAM systems and optimization thereof

Milling strategies for machining dental ceramic materials are provided that reduce milling time while maintaining strength, accuracy and marginal integrity.

Machining of ceramic materials

A method and system for the fabrication of dental articles includes at least two imaging and measuring devices, which measure and provide images of the internal and external structure of intra-oral objects in a patient's oral cavity. The outputs from these devices are linked so that the descriptions of the intra-oral objects and features, oral cavity and surrounding bone structure are stored in a system of reference positions. The system of reference positions functions as a 'global positioning device' registering locations and orientations of the measuring and imaging device or probe relative to the intra-oral objects and bone structure and orientations of the resulting individual frames or scans in the global system of coordinates. Three-dimensional images, scans and/or maps of the oral cavity obtained from each device are pieced together to generate solid three-dimensional models of the intra-oral objects.
