Abstract: A method for preparing a multilayer-color composite material for use in dental department comprises: preparing multiple types of monochromatic composite material precursor powder different in color, carrying out dry-pressing and preforming on the precursor powder, so as to obtain a preformed green body; and then carrying out pressurization and heating processing on the preformed green body, so as to obtain a multilayer-color composite material that gradually changes in color from neck portions to incisal ends of teeth, so that the multilayer-color composite material has a higher similarity to the material of natural teeth.

Abstract: The examples of the present application disclose a method for preparing a dental composite resin material and articles prepared therefrom, wherein the method comprises: (1) weighing in each of raw materials, including ethylenically unsaturated monomer, reinforcing fiber, filler, initiator, polymerization inhibitor and colorant; (2) mixing the weighed raw materials except reinforcing fiber, obtaining a composite resin monomer precursor; (3) impregnating the weighed reinforcing fiber into the composite resin monomer precursor for 1-5 hours, preferably 2-3 hours, at an impregnation negative pressure of less than or equal to 0.1 MPa, obtaining a composite resin monomer precursor-immersed reinforcing fiber; and (4) subjecting the composite resin monomer precursor-immersed reinforcing fiber to a solidification treatment, obtaining the dental composite resin material.

Abstract: Techniques are presented herein for switching between a software decoder and a hardware decoder in a hybrid decoder. A video bit stream is received. The video bit stream is analyzed to determine whether or not the video bit stream can be decoded by the hardware decoder. When the video bit stream can be decoded by the hardware decoder, the video bit stream is routed to the hardware decoder and also stored in a first buffer. The video bit stream is decoded by the hardware decoder and when a reference frame is decoded, the reference frame is stored in a second buffer. When the video bit stream cannot be decoded by the hardware decoder, the video bit stream is routed to the software decoder for decoding. When an instantaneous decoder refresh (IDR) frame is decoded by the software decoder, the IDR frame is stored in the first buffer.

Abstract: A preparation method of lithium metasilicate glass ceramic, comprises (a) preparing a melt of glass matrix; (b) pouring the melt of glass matrix into a mould, and cooling to obtain a blank of glass matrix; (c) placing the blank of glass matrix in a heating device to carry out heat treatment, the process parameters of which include: heating to a temperature of 450-600° C. under a heating rate of 5-20° C./min, and keeping the temperature for 20-150 min; and cooling along with the heating device to obtain the lithium metasilicate glass ceramic after the heat treatment. Compared with the prior art, in the resulted lithium metasilicate glass ceramic, the main crystal phase of lithium metasilicate exhibits the crystal morphology of sphere which is in nano-size and uniform. The lithium metasilicate glass ceramic is low in crystallization degree, and thus has reduced hardness.

Abstract: The present invention relates to a method for changing translucency of zirconia dental materials through applying an yttrium or ytterbium salt solution onto a pre-sintered zirconia material by dipping or brush-coating. Accordingly, the need of young patient in relation to the translucent requirement for incisal portion of anterior teeth is met in which the translucent level from the crown neck to the incisal portion is gradually changed in a natural manner, similar to natural teeth. A color gradient effect of the crown is produced through dipping in or brush-coating with yttrium or ytterbium salt solution. Moreover, the present invention involves simple operating steps and low cost while providing high consistency in quality.
