Description
Technical field
The present invention relates to a kind of artificial tooth, particularly, relate to a kind of Zirconium dioxide full porcelain tooth and preparation method thereof.
Background technology
Be applied in artificial tooth clinically now, hat adopts the nichrome material usually in it, and this artificial tooth processing technology often need be added beryllium element; Because artificial tooth need be bonded in the oral cavity for a long time, but the beryllium element that contacts for a long time in the artificial tooth can be harmful, and some crowd; Especially women; Can produce anaphylaxis to nickel, make the gingiva blackout, injury is healthy and attractive in appearance.If the artificial tooth of inlaying in the oral cavity is metallic ceramic crown, when needs are done head X line, CT, nuclear magnetic resonance check, will be affected even remove.
In addition, also have and adopt the artificial tooth that hat (promptly casting porcelain) is made in the full porcelain of casting die mould, this casting ceramic material is more transparent, for the darker tooth of color, and the reparation of uncomfortable cooperation casting porcelain; Because cast the insufficient strength of ceramic material, backteeth is not suitable for doing the reparation of casting porcelain, and adopts the artificial tooth fixed bridge structure maximum of casting ceramic material making can only be 3 units, promptly comprises the artificial tooth fixed bridge structure (supporter of hat and both sides in comprising) of single interior hat.
Also have at present and use the artificial tooth that alumina material is made interior hat, but, only be fit to do single artificial tooth, be not suitable for making the artificial tooth of large span fixed bridge structure because the alumina material insufficient strength is high.
Summary of the invention
The invention provides a kind of artificial tooth of making large span fixed bridge structure, this artificial tooth adopts hat and supporter in the zirconium dioxide material, safe, attractive in appearance, good biocompatibility, and obdurability is good.
In order to achieve the above object, the present invention provides a kind of Zirconium dioxide full porcelain tooth, comprises artificial tooth fixed bridge structure, and the glaze enamel coating that is coated on this artificial tooth fixed bridge structural outer surface;
Described artificial tooth fixed bridge structure adopts the zirconium dioxide material to process, and it comprises hat in some mutual agglutinating artificial teeth, and can sheathedly be bonded to the supporter on the human teeth;
The inside of described supporter is hollow, and it is connected respectively to the both sides of hat in the artificial tooth;
The shape of said supporter inner hollow with agreed with mutually by sheathed human teeth's shape, through polishing, shape is less than normal tooth for this tooth, utilizes medical binding agent with tight seamless being bonded on the tooth of polishing of supporter;
Described glaze enamel coating adopts ceramic material; Described ceramic material, abrasion resistance is strong, has prolonged the service life of artificial tooth;
Further, the invention provides a kind of manufacture method of Zirconium dioxide full porcelain tooth, may further comprise the steps:
Step 1, the tooth that need make artificial tooth to human body carries out data acquisition, the correction of three-dimensional parameter, and reduction obtains the tooth model of emulation;
Step 2, the cutting and grinding of artificial tooth fixed bridge structure: according to the tooth model of the emulation of step 1 gained, adopt the cutting and grinding device that the zirconium dioxide material is carried out numerical control cutting, form zirconium dioxide artificial tooth fixed bridge structure;
Step 3, the firing of artificial tooth fixed bridge structure: the zirconium dioxide artificial tooth fixed bridge structure of cutting forming is placed sintering in the calciner plant;
Step 4 on the artificial tooth fixed bridge structure of calcining after the intensive treatment, uses the porcelain powder of coupling to pile moulding attitude, and dyeing, glazing, forms the glaze enamel coating, accomplishes the making of whole Zirconium dioxide full porcelain tooth.
Further, above-mentioned steps 1 comprises:
Step 1.1 adopts laser scanning device that the human teeth is carried out non-contact optical scanning, obtains the three-dimensional parameter data of tooth;
Step 1.2 adopts data to read the three-dimensional parameter data that prosthetic device obtains above-mentioned tooth, and the edlin of going forward side by side is handled, and the digitalized data that will handle then is reduced to the emulated tooth image.
Further, in the above-mentioned steps 1.2, data read prosthetic device obtains tooth from data acquisition unit through extraneous storage medium or telecommunication network three-dimensional parameter data.
The present invention also provides another kind of technical scheme, and difference only is step 1, and other steps are identical.This step 1 comprises:
Step 1.1, the tooth that need make artificial tooth to human body carries out delivery, records plaster model;
Step 1.2 adopts resin material, according to above-mentioned plaster model, makes the interior hat or the support model of artificial tooth fixed bridge structure.
The Zirconium dioxide full porcelain tooth manufacture method that the present invention adopts; Comprise data acquisition, artificial tooth fixed bridge structure cutting and grinding, artificial tooth fixed bridge structure fire and go up the porcelain modification; Wherein, The tooth emulation that omnibearing 3-D scanning mode can produce high-resolution is original image also, makes that the parameter of making the artificial tooth that obtains is more accurate, the human oral cavity of more fitting.
Said Zirconium dioxide full porcelain tooth density and intensity are very high, and its anti-fracture strength is up to the 800-1000 MPa, and obdurability is good, can make the above artificial tooth fixed bridge structure of 6 units, and the artificial tooth that has solved prior art can not be made the problem of large span fixed bridge structure; The Zirconium dioxide full porcelain tooth material is compared with other artificial tooth repair materials, and the advantage on its intensity makes mill that the doctor need not be too much remove patient's dermal tooth, just can reach high intensity; Nonmetallic zirconium dioxide does not have any stopping to the X line, the Zirconium dioxide full porcelain tooth of yet need not dismantling when the patient need do head X line, CT, nuclear magnetic resonance check; Adopt the porcelain powder heap of coupling to mould, dyeing, glazing, the glaze enamel coating that makes makes the Zirconium dioxide full porcelain tooth color and luster natural, attractive in appearance; The zirconium dioxide good biocompatibility, the irritated reaction of, nothing non-stimulated to gingiva has reduced the stimulation of other tissue of boil on the nape opposite the mouth intracavity, thereby has reduced the possibility of pathological changes.
Zirconium dioxide full porcelain tooth provided by the invention, free from extraneous odour does not have toxicity to human body, can not make gingival discoloration yet, and intensity is high, can make large span fixed bridge structure.
Description of drawings
Fig. 1 is the structural representation of a kind of Zirconium dioxide full porcelain tooth provided by the invention.
The specific embodiment
Followingly specify preferred embodiments of the present invention according to Fig. 1:
