Description
Technical field
The present invention relates to dental prosthesis with ceramic, particularly a kind of colored glass pottery for making dental prosthesis and preparation method thereof.
Background technology
Stupalith is because of its good biological safety and aesthetic property, and is more and more extensive in the application in field, oral cavity, and become emphasis and the focus of Oral Repair area research.Dental porcelain mainly comprises: feldspathic china, glass-ceramic, alumina ceramics and zirconium oxide porcelain.
Feldspathic china is low brilliant ceramic material, and its crystalline component is few, structurally closer to glass.The dental case permeability made from this class pottery is high, have good aesthetic property, but its flexural strength is usually lower, can only be used as finishing material or be used for making inlay and veneer of anterior tooth.Interpolation white garnet, mica etc. can carry out this class material toughness reinforcing, but the raising of the intensity of the material after toughness reinforcing is limited, still is confined to make inlay, labial teeth leaf-comb and veneer.
Alumina-ceramic and zirconia ceramics are the highest dental porcelains of physical strength, but its optical property is relatively poor, pure aluminum oxide and zirconium oxide porcelain present opaque white, light transmission is little, the making of multiplex stratum basale in all kinds of dummies, dummy aesthetic property and the emulation made are relatively poor, are not suitable for the aesthetics reparation for labial teeth.
Glass-ceramic is crystalline phase and the equally distributed polycrystalline solids of glassy phase that is made by controlling crystallizing by host glass, and it has concentrated the characteristics of pottery and glass.Separate out crystalline phase by thermal treatment process, the strength of materials and toughness are improved; In addition, containing the glassy phase of certain content due to glass-ceramic, possess outstanding semi-transparent characteristic, can farthest reproduce color and luster and the light transmission features of natural teeth, is the aesthstic preferred material of repairing of labial teeth.Increasing glass-ceramic product by Application and Development in succession in the Oral Repair field.But, substrate porcelain (core porcelain) color category of Dental Glass Ceramics is less at present, color as IPS e.max substrate porcelain only has 3~5 kinds, and the color category of clinical dentistry color board commonly used is more than 16 kinds, therefore, there is the inconsistent problem of color with the dentistry color board in the dummy of making of the substrate porcelain of present commercial glass-ceramic, needs when usually making dye to it.
