Abstract
The invention discloses a preparation method for a dental zirconia ceramic restoration. The preparation method for the dental zirconia ceramic restoration comprises the following steps: weighing, grinding, stirring and drying. The dental zirconia ceramic restoration obtained in the invention has high hardness; since a 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; used raw materials are widely available and beneficial for human health; and since a 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. The preparation method for the dental zirconia ceramic restoration is simple to operate, convenient in preparation, low in cost and suitable for industrial large-scale production.
Description
Technical field
The invention belongs to dental materials field, be specifically related to the preparation method of a kind of dental zirconia ceramics dummy.
Background technology
Flos Lonicerae is dry flower or the first flower opened of band of caprifoliaceae plant Radix Ophiopogonis.In bar-shaped, upper coarse and lower fine, slightly curved song,
Long 2～3cm, upper diameter 3mm, lower diameter 1.5mm, surface yellow-white or green white, close by pubescence.Flos Lonicerae is extracted
Thing, extracts from honeysuckle flower, and Main Ingredients and Appearance is chlorogenic acid.Can be as medicine, health product, the raw material of cosmetics.Modern
Medical research proves, Flos Lonicerae is for streptococcus, staphylococcus, Bacillus typhi, dysentery bacterium, large intestine and bacillus pyocyaneus, pneumonia
Diplococcus, bordetella pertussis, meningococcus etc., have stronger antibacterial power, and treatment influenza and inflammation are all had one
Constant current modulation is imitated.
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.
