An oven () for heating a dental object (), having a chamber () for receiving the dental object (); a radiation source () for emitting radiation having a wavelength smaller than 350 nm into the chamber (); and heating means () for heating the dental object () in the chamber ().

Oven for heating a dental object

A method for layer-wise additive manufacturing of a shaped body made up of slices of processed layers, including the steps: A laser induced forward transfer (LIFT) process utilizing a laser to direct laser beam pulses acts on a coating of slurry on a carrier to transfer droplets of slurry to a receptor surface to create the slurry layer which is then processed further by above-mentioned steps of solidifying, and debinding and/or sintering.

A process for the preparation of multi-coloured dental restorations is described, in which glasses and glass ceramics with various compositions are given the shapes of dental restorations and colour changes are effected in the glasses and glass ceramics by irradiating them with artificial electromagnetic radiation and subjecting them to a heat treatment.

Method for manufacturing a multi-color dental restoration

Glass ceramics having SiOas main crystal phase and precursors thereof are described which are characterized by very good mechanical and optical properties and in particular can be used as restoration material in dentistry.

Glass ceramic having SiOas main crystal phase

The present invention relates to a pre-sintered multi-layered dental mill blank comprising a top layer, a bottom layer, and at least one intermediate layer. The pre-sintered multi-layered dental mill blank or a part prepared thereof has one or more desirable properties when being fully sintered by a speed sintering process. The present invention also relates to a process for preparing a dental restoration using the pre-sintered multi-layered dental mill blank as well as to a dental restoration as such. The present invention further relates to a process for sintering a dental restoration precursor.

Process and slip for the production of ceramic shaped parts made of zirconium oxide ceramic by a 3D inkjet printing process. The slip contains zirconium oxide which is suspended in a liquid medium, wherein the slip has a zirconium oxide content of from 68 to 88 wt.-% and contains not more than 5 wt.-% organic components. The process for the production of ceramic components comprises the layered shaping and subsequent sintering of the desired component from the slip.

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 a process for the preparation of a glass-ceramic blank for dental purposes with lithium silicate as crystal phase, in which lithium silicate blanks that are no longer required and in particular residues thereof are used as starting material and which allows the production of a homogeneous starting glass within a short time.

The invention relates to glass ceramics and glasses with a europium content, containing the following components: and which are suitable in particular for the production of restorations, the fluorescence properties of which largely correspond to those of natural teeth.

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

Lithium silicate-low quartz glass ceramics are described which are characterized by a combination of very good mechanical and optical properties and can therefore be used in particular as restoration material in dentistry.
