Description
Technical field
The invention belongs to oral restoration adhesive technology field, a kind of method for being related to negative pressure to improve mouth mending material bonding.
Background technology
Due to the raising to aesthetic requirement, various new dental materials constantly come out.Zirconia ceramics is due to height
The premium properties such as hardness, high intensity, high tenacity, high chemical resistance and wearability, while having excellent aesthetic beauty
Energy and biocompatibility, are increasingly becoming the preferred material of fixed reparation, and it is fixed the range of application repaired and constantly expands, but is bonded
The phenomenon of failure clinically still has generation, it is considered to be cause to fix one of common cause of repairing failure.Current dental
Zirconium oxide prosthesis, such as veneer, hat, inlay are to make (CAD/CAM) technology by CAD/area of computer aided
It is accurate to make, but due to its surface high stability, make its be difficult to produce between bonding agent preferable chemical bond with it is more
Mechanical fixing so that being difficult to set up the bonding of lasting stability.Hydrofluoric acid acid etching and silane coupler treatment are aoxidized to improving
Zircon porcelain adhesive strength works little, limits zirconia ceramics in sides such as abutment retention form is bad, part veneer, hat, inlays
The application in face.On the other hand, clinically dummy is various shapes personalized, and mouth mending material be bonded and fixed to oral cavity it
Before be independently of outside human body individuality, improve that bonding agent is bonding with dummy can effectively to be prevented and reduce in vitro using preceding
Bonding loosely waits reparation problem, improves the service life of dummy.Research suction function of the invention main in have been coated with silane coupling agent,
Influence of the individualized therapy body bonding plane of the various shapes of bonding agent etc. to dummy adhesive strength.
The content of the invention
Situations such as the object of the invention is directed to not firm enough the various individualized therapy body bonding of current shape shape, poor durability
And a kind of method that the negative pressure-normal pressure or pressurization invented improve dummy bonding, painting is made by the process of negative pressure-normal pressure or pressurization
Cloth is more fitted in the bonding agent for treating vertex-gluing graph body bonding plane with dummy surface, is effectively increased silane coupling agent, bonding agent and is penetrated into
The depth and dummy of dummy and the closed intensity of bonding agent, effectively increase bond area and mechanical interlock maintenance, while
The intermolecular force between bonding agent and dummy is increased, to increase bonding agent with the cementation position of dummy and durability.
To achieve the above object, the technical solution adopted by the present invention is as follows.
The present invention is a kind of method of the individualized therapy body bonding that external negative pressure improves various shapes, it is characterised in that
The adhesive surface for treating vertex-gluing graph body is processed (this is conventional technique method, such as sandblasting, cleaning), is then coated with primary coat
One or more in agent, bonding agent etc., before the solidification such as silane coupling agent, bonding agent, will treat that vertex-gluing graph body is integrally placed into negative
Pressure case, then carries out taking out negative pressure to negative pressure box, and then suction function releases negative pressure and cause in the surface for integrally treating vertex-gluing graph body
Negative pressure box back to nature atmospheric pressure is that normal pressure or inflation further to negative pressure box are pressurizeed, the negative pressure-normal pressure or negative pressure-pressurization
Process carry out repeatedly.In the adhesive surface of vertex-gluing graph body when the adhesive surface of vertex-gluing graph body is under condition of negative pressure, is treated
Gas (gas predominantly between silane coupling agent or bonding agent and dummy in gas or bonding agent) discharged because of negative pressure, work as recurrence
When normal pressure or pressurization, it is covered in flowable silane coupling agent, bonding agent of dummy adhesive surface etc. and takes advantage of a situation reparation of in depth penetrate into
In the minim gap of body gluing of surfaces, that is, effectively improve silane coupling agent, bonding agent penetrate into dummy depth and dummy with it is bonding
The closed intensity of agent, effectively increases bond area and chimeric maintenance, while increased the molecule between bonding agent and dummy
Intermolecular forces, so as to effectively improve adhesive property.
Silane coupling agent, bonding agent do not solidify during above-mentioned negative pressure-normal pressure or negative pressure-pressurization.
Described negative pressure pressure is that, less than the pressure of normal pressure 0.1MPa, until reaching relative vacuum, described being pressurised into is higher than
The pressure of normal pressure 0.1MPa and the above, because outside the negative pressure or pressurized treatments are independently of human body.
Described remaining bonding process can be operated as needed.
The depth and density penetrated into using the inventive method silane coupling agent, bonding agent etc. in dummy bonding plane are substantially increased
Greatly.The individualized therapy body that the method is applied to various shapes is bonded.
Dummy of the present invention carries out negative pressure (or pressurization) treatment in vitro, and negative pressure (or pressurization) regulation limitation is reduced, safety
It is easy.
