Description
Technical field
This utility model belongs to Dental Erosion technical field of tools, particularly relates to a kind of all-ceramic prosthesis of Rotating fields in gradient.
Background technology
At present, zirconium oxide all-ceramic prosthesis is with its high strength, high accuracy and outstanding biocompatibility, one of main stream approach becoming All-ceramic restoration.But document is pointed out, in real oral environment, in zirconium oxide core porcelain tissue surface, tensile stress concentrates the radial crack caused, and meeting is constantly expanded and causes the destruction of all-ceramic crown under stress corrosion.There are some researches show, after adopting resinoid bond to be connected with dentin by all-ceramic crown, the fold resistance of porcelain can be improved to a great extent.But however, nearly all Experiments of Machanics still find that core porcelain tissue surface is the most concentrated position of tension, become the maximum latency that all-ceramic prosthesis destroys.All-ceramic prosthesis and dentin have been linked to be one by binding agent, and from occlusal surface, total is followed successively by facing porcelain, zirconium oxide core porcelain, binding agent, dentin.Research finds, the elastic modelling quantity of zirconium oxide core porcelain will, much larger than facing porcelain, resinoid bond and Dentinal elastic modelling quantity, therefore very easily cause the stress on interface to concentrate in loading process.Therefore, how to make hat after stressed, the transmission of stress energy steady and smooth in whole zirconium oxide All-ceramic restoration body structure, to avoid and the stress reduced at interface is concentrated, thus toughening effect is played to all-ceramic prosthesis, improve and repair success rate and become very important.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of all-ceramic prosthesis of Rotating fields in gradient, from surface to inside, elastic modelling quantity increases gradually, change in continuous gradient, thus material character and function are also changed in gradient, stress can be made stably to ceramic material internal delivery, the tension of effective minimizing ceramic material outer surface (interface) is concentrated, and the stretching, extension of crackle can be stoped, thus strengthen the ability of pottery opposing destruction, play toughening effect.
This utility model solves the technical scheme that its technical problem adopts: the all-ceramic prosthesis providing a kind of Rotating fields in gradient, comprise and be connected to innermost layer articulamentum on this tooth and outermost layer finish coat, described articulamentum outer wrapping stress layer, described stress layer take pre-sintering temperature as the infiltration glass zirconia layer of 900 to 1000 degrees Celsius, described stress layer outer wrapping contact layer, described contact layer wraps up stress layer completely, and stress layer is not contacted with gingiva, described contact layer is pure zirconia zirconium layer, described contact layer outer wrapping finish coat, described finish coat only wraps up contact layer top, do not contact with gingiva.
The thickness of described finish coat is 0.3 millimeter.
The thickness of described contact layer is 0.8 to 1.2 millimeters.
The thickness of described stress layer and articulamentum is 1.2 to 1.5 millimeters.
Beneficial effect
The utility model has the advantage of, from surface to inside, elastic modelling quantity increases gradually, change in continuous gradient, thus material character and function are also changed in gradient, stress can be made stably to ceramic material internal delivery, the tension of effective minimizing ceramic material outer surface (interface) is concentrated, and the stretching, extension of crackle can be stoped, thus strengthen the ability of pottery opposing destruction, play toughening effect.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth this utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of this utility model.In addition should be understood that those skilled in the art can make various changes or modifications this utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read this utility model instruction.
As shown in Figure 1, a kind of all-ceramic prosthesis of Rotating fields in gradient, comprise and be connected to innermost layer articulamentum 2 on this tooth 1 and outermost layer finish coat 5, described articulamentum 2 outer wrapping stress layer 3, described stress layer 3 take pre-sintering temperature as the infiltration glass zirconia layer of 900 to 1000 degrees Celsius, described stress layer 3 outer wrapping contact layer 4, described contact layer 4 wraps up stress layer 3 completely, and stress layer 3 is not contacted with gingiva, described contact layer 4 is pure zirconia zirconium layer, described contact layer 4 outer wrapping finish coat 5, described finish coat 5 only wraps up contact layer 4 top, do not contact with gingiva.
The thickness of described finish coat 5 is 0.3 millimeter.
The thickness of described contact layer 4 is 0.8 to 1.2 millimeters.
The thickness of described stress layer 3 and articulamentum 2 is 1.2 to 1.5 millimeters.
In actual applications, by progressively changing the zirconic pre-sintering temperature of infiltration glass from inside to outside, whole solid of repairing is presented from surface to inside, elastic modelling quantity increases gradually, the state of the change in continuous gradient, what first sinter is larger at stress layer 3 elastic modelling quantity of inside, inwardly 240GPa (120 μm of places) is increased to gradually from the 110GPa (0 μm) on surface, and fracture strength is higher, and outer field contact layer 4 elastic modelling quantity that to be pure zirconia zirconium layer relative is less, therefore need with relatively little thickness, the stress layer 3 that parcel is inner, the biocompatibility utilizing pure zirconia good contacts with gingiva, effectively can prevent allergy, the generation of the unfavorable condition infected.
