Abstract
The invention discloses a dental zirconia ceramic restoration. The dental zirconia ceramic restoration comprises the following raw materials by weight: 6 to 17 parts of zirconia, 0.5 to 1.0 part of alumina, 10 to 25 parts of ceramic powder, 25 to 48 parts of starch, 3 to 12 parts of yttrium oxide, 0.5 to 2.5 parts of a dispersing agent, 1.5 to 3 parts of a water-soluble binder, 0.3 to 2 parts of honeysuckle flower extract and 0.5 to 5 parts of a coloring agent. The dental zirconia ceramic restoration obtained in the invention has high hardness; since the dispersing agent and honeysuckle flower extract are used as the components of the restoration, the problems of frangibility, low glossiness, poor color contrast performance, low transparency and poor antibacterial performance of an all-ceramic material are overcome; the used raw materials are widely available and beneficial for human health; and since the coloring agent is used as a component of the dental zirconia ceramic restoration, individual needs of modern society are met and wide market prospects are obtained.
Description
Technical field
Dental materials field of the present invention, is specifically related to a kind of dental zirconia ceramics dummy.
Background technology
Dispersant (Dispersant) is a kind of to have lipophile and two kinds of opposite nature of hydrophilic in intramolecular simultaneously
Interfacial agent.Can homogeneous dispersion those be poorly soluble in liquid inorganic, the solid of organic pigment and liquid particles, the most also
Sedimentation and the cohesion of granule can be prevented, form the amphipathic reagent needed for stable suspension.Dispersant can promote gloss, prevent
Floating, minimizing flocculation, increase color developing, increase color saturation, increase transparency.
The development of Oral Repair is inseparable with the development of oral cavity material and technique, dentures repai material mainly have pottery,
Resin and metal material.And the ceramic material own intensity deficiency of traditional glass ceramics base and alumina base and fragility are relatively big,
Easily rupturable, limit its use in the reparation in oral cavity.
Along with developing rapidly of current recovery technique of oral cavity, All-ceramic material is by feat of self good biocompatibility, resistance to
A series of speciality such as corrosivity, dielectricity, heat stability and excellent aesthetic effect, become currently used widest oral cavity
Repair materials.The All-ceramic material generally making artificial tooth mainly has aluminium oxide and zirconium oxide, and aluminium oxide has good anti-wear performance,
But fragility is relatively big, easily rupturable, zirconium oxide makes it produce stable four directions due to the effect of mixing of other oxides by contrast
Crystalline phase, therefore, zirconia ceramics has high tenacity, high-flexural strength and high-wearing feature.Therefore, zirconia ceramics is to be currently used for
The All-ceramic material that in the full magnetic material of Oral Repair, mechanical performance is best, suitably as dental prosthesis.But pure zirconia is made pottery
The ceramic product that porcelain sinters out is white, and single this color is difficult to meet the most personalized social need, and mesh
Front dental zirconium oxide prosthesis needs to improve on hardness, anti-inflammation and glossiness, color developing etc., is badly in need of exploitation new
Material.
