Description
Technical Field
The invention relates to the technical field of zirconia ceramic blocks, in particular to a coloring agent and an accelerator for high-precision dyeing of zirconia ceramic blocks.
Background
Currently, in prosthodontics, color and light transmission are important indicators that affect the objectivity of restorations and teeth. The dental CAD/CAM technology is used for manufacturing the all-ceramic restoration, and a new way is opened up for the automatic processing of the restoration and the manufacturing of the high-strength all-ceramic crown bridge. The uncolored zirconia ceramic block is mostly white to ivory in color, and although the uncolored zirconia ceramic block can simulate the color of natural teeth to a certain extent, the uncolored zirconia ceramic block cannot meet the requirement of clinical restoration body color. Only when the zirconium oxide is colored, the color and the light transmittance of the zirconium oxide are adjusted to be close to those of the teeth to be restored, and the requirements of customers can be met. The existing coloring technology of zirconia ceramic blocks mainly comprises an internal dyeing method and an external dyeing method, wherein the internal dyeing method is to directly and uniformly add coloring oxides into powder, and the external dyeing method is to permeate dyeing liquid containing coloring matters into a dental pre-sintered blank body through soaking, brushing and the like, dry and sinter the blank body to form the dental pre-sintered blank body.
at present, colored full-ceramic zirconia materials are also used for tooth restoration to replace the traditional method of using color-shading ceramics, and the coloring method comprises two methods of endogenous coloring and exogenous coloring. The internal dyeing method is characterized in that colored rare earth metal oxide is mixed in powder, and the method can play a role in enabling the tooth coping to have color. The extrinsic dyeing is to soak the ceramic presintered body in a dyeing solution for 1-30min, dry and sinter to form. Although the two methods are fast and easy to operate, the two methods have more influencing factors and are easy to cause uneven dyeing, and after dyeing, denture processing procedures such as porcelain glazing and the like are still needed, so that the possibility of denture porcelain collapse still exists, and finally the application of the product fails.
For example, as disclosed in CN203749621U, a zirconia ceramic block with gradation change in color is obtained by a technique of making blanks from multiple layers of materials with different colors, but the color change is harsh and inconsistent; theoretically, as long as the number of layers is increased, the color change tends to be more natural and uniform, but from the aspect of a forming process, the number of layers cannot be increased too much, and the processing difficulty and the cost are increased. Other technical schemes propose a process of dip dyeing a dyeing solution and then sintering. However, the dip dyeing process can cause the change of some physical and chemical characteristics of the ceramic block blank, and the physical properties such as the strength of the finished ceramic block are affected. Therefore, the technical problem of manufacturing the zirconia ceramic block with uniform gradient color still cannot be reliably solved in the prior art.
