The cast porcelain material contains a colorant with the weight not more than 0.5%, and the colorant contains one or more of Pr, tb, cr, nd, co and oxides thereof. That is, a coloring agent is added to the cast porcelain material, and preferably, the content of the coloring agent is 0.1% to 0.2%.
In the related art, a pre-sintered zirconia is colored by dipping, painting or spraying a solution using a metal ion coloring solution or a metal complex coloring solution of a pre-sintered ceramic, or a zircon-based pigment is mixed with a Y-containing pigment 2 O 3 And partially stabilized zirconia such as MgO. The addition of these colorants can have a negative impact on mechanical properties such as strength and fracture toughness, as well as on shrinkage and sinter density. This occurs for a number of reasons, including: the transformation toughening effect is reduced due to excessive stabilization of the tetragonal phase by the additive, thereby reducing fracture toughness, or the excessive grain growth due to the additive may result in spontaneous microcracking resulting in loss of strength, or the formation of strength-limiting pores in the microstructure resulting in loss of strength.
Herein, one or more colorants incorporated into the ceramic material of the sintered ceramic veneer body 10 are selected to impart a natural tooth color to the sintered shaped veneer body 10. In a specific sintering process, the ceramic casting material powder and the one or more colorant powders can be mixed, and after mixing, the veneering body 10 can be obtained by a conventional sintering process, the veneering body 10 after sintering can have natural tooth color, and the obtained veneering body 10 has excellent mechanical properties, and the addition of the colorant has almost no influence on the mechanical properties of the veneering body 10.
The modified coating 11 is coated on the inner surface S11 of the veneer 10, and the modified coating 11 is a ceramic slurry containing 8 to 20% by weight of an additive capable of forming crystalline metallosilicate. That is, the ceramic slurry contains 8% to 20%, preferably 10%, of an additive capable of combining with the silica in the ceramic slurry to form a crystalline metallosilicate, for example, by coating the ceramic slurry on the inner surface S11 of the veneer 10 and firing at a high temperature (e.g., 1200 degrees celsius) to form a glass ceramic of the crystalline metallosilicate, and the crystalline metallosilicate is doped in the ceramic to improve the toughness and fracture resistance of the ceramic.
A bonding layer is formed on the inner surface of the modified coating layer 11 and the bonding layer contains a fluorinated metal oxide to fix the non-molar modified porcelain veneer member to the tooth surface by bonding the bonding layer with a silane coupling agent.
In the related art, the ceramic veneers are usually fixed on the tooth surface by bonding with adhesives, however, the traditional bonding method can not provide high bonding strength, and the problems of unreliable bonding of the ceramic veneers, short service life and the like are caused.
In the present application, on one hand, the inner surface of the facing body 10 is fluorinated (for example, plasma fluorination treatment process) by using a fluorine-containing agent, such as but not limited to sulfur hexafluoride, etc., the facing body 10 may contain metal oxide, such as yttrium oxide, zirconium oxide, aluminum oxide, etc., after the fluorination treatment, fluorinated metal oxide is formed on the ceramic facing surface, and the treated surface has better hydrophobicity and stronger reactivity, and on the other hand, during the mounting process, the surface of the fluorinated metal oxide is coated by using a silane coupling agent, and silane is generally a bifunctional group with dual reactivity, including but not limited to vinyl, allyl, amino or isocyanate group, and is generally capable of reacting with inorganic and organic substrates. The silane may contain one or more other substituents that may be reactive, including chlorides and the like. The silane undergoes hydrolysis and condensation reactions with the fluorinated metal oxide surface.
According to the non-molar modified porcelain facing component provided by the embodiment of the invention, the modified coating 11 is coated on the inner surface S11 of the facing body 10, so that the modified coating 11 can form the crystalline metallosilicate, and the crystalline metallosilicate in the porcelain can improve the toughness of the porcelain and inhibit the fracture expansion in the porcelain, thereby ensuring that the non-molar modified porcelain facing component is not easy to fracture and has longer service life. In addition, one or a combination of more of Pr, tb, cr, nd, co and oxides thereof is used as a colorant, and the negative effect of the colorant on the performance of the porcelain facing component can be reduced to a minimum degree on the premise of matching the desired natural tooth color. The bonding layer containing the fluoridated metal oxide is formed by performing fluoride treatment on the surface by using a fluorine-containing reagent so as to enable the surface to be better hydrophobic, and meanwhile, silane is applied to the surface, can perform hydrolysis and condensation reaction with the surface and is bonded and fixed to the surface of the tooth by using an adhesive, so that the bonding reliability can be remarkably improved.
It should be noted that, based on the requirements of color, mechanical properties and adhesion reliability, the application combines the use of a colorant different from the conventional process, the use of a modified coating 11 containing a crystalline metallosilicate, and the hydrolysis and condensation reaction of a fluorination treatment technique and a silane coupling agent, and finally, a ceramic veneering member with natural color and luster, mechanical properties and reliable adhesion can be obtained, which has a significant meaning for dental restoration.
Preferably, the additive is metal, metal oxide or metal salt, more preferably, the additive is one or more of aluminum, sodium, calcium, magnesium, potassium, iron and yttrium oxide, for example, the additive is yttrium oxide, and the yttrium oxide and the silicon dioxide in the ceramic slurry can form crystalline yttrium silicate under high temperature firing.

In addition, in the bonding process, air between the tooth surface and the modified ceramic layer can be quickly exhausted from the center to the outer side along the radiation grooves H111, and the air can be exhausted as far as possible, so that the bonding force is improved, and the problems of poor bonding, strength reduction and the like caused by the existence of air bubbles are solved.
