Description
Technical field
This utility model relates to a kind of full zirconium dioxide artificial tooth (comprising leaf-comb and fixed bridge).
Background technology
Label the corona that the facing porcelain constitutes in traditional, if interior hat material coefficient of thermal expansion coefficient (CTE) value is obviously low than finishing material, the tangent line tensile stress will increase and cause outside crack; May cause the later stage crack; If the CTE value of interior hat material is obviously than finishing material height, the tangent line compressive stress may cause increase and the appearance crack parallel with interior hat to scale off.If interior hat material uses the ceramic material facing, the thickness of porcelain powder is another deciding factor except that the CTE value.Therefore, thickening of coating can obtain increasing radiation tensile stress.
Do backteeth because the corona of zirconium dioxide and bridge are commonly used, the masticatory force that bears is bigger, uses to be preced with in the zirconium dioxide to reglaze the face enamel coating, may cause easily and collapse porcelain; And the process more complicated of last glaze enamel coating, cost increases.
