Description
Technical field
This utility model relates to a kind of medical prosthesis, belongs to medical instruments field; Particularly, relate to a kind of invisible false tooth.
Background technology
People thought once that removable denture must be very firm, just can wear.So traditional metal rack recovery technique focuses on the stability and the holding power of balance maintenance, and design is complicated.Conventional metals snap ring-type artificial tooth comprises the metal rack snap ring of artificial tooth, basal seat area and fixed denture base, and metal clasp is apparent, influences natural, the aesthetic feeling of tooth; And the comfortable wearing sense is poor, has foreign body sensation, easily broken folding, and metal is heavier, has thick and heavy sense, and metal clasp easily causes dull pain to the burden of residual tooth, easily sticks to one's teeth, even may cause metal allergy.
, people increasing along with allergic constitution person proportion in the crowd have bio-compatibility, attractive in appearance, natural to the raising of requirement attractive in appearance, comfortable and easy to use, and the demand of light, comfortable artificial tooth further enlarges.
The utility model content
The purpose of this utility model provides a kind of removable denture, and this artificial tooth is consistent with human body gingiva color and luster, nature true to nature, and have good, light, the comfortable and high strength of pliability, do not produce metal characteristics hypersensitive.
In order to achieve the above object, this utility model provides a kind of invisible false tooth, this artificial tooth comprises: basal seat area and be arranged on artificial tooth corona on the basal seat area, described basal seat area adopts the thermoplastic elastomer resin material to make, described artificial tooth corona is provided with some apertures, described basal seat area and artificial tooth corona connect with fusing mode by the aperture on the artificial tooth corona.
Above-mentioned invisible false tooth, wherein, described aperture is arranged on the downside of artificial tooth corona, and the position that is covered by the basal seat area welding.
Above-mentioned invisible false tooth wherein, connects between described some apertures, so that the artificial tooth corona firmly closely is connected more with basal seat area.
By the fusing mode physical connection, not needing influences snap ring attractive in appearance, has alleviated the burden to residual tooth, can not produce to stick to one's teeth and metal problem hypersensitive between described basal seat area and the artificial tooth corona.
Described basal seat area also comprises the connecting portion that connects the human teeth, further helps fixedly connected invisible false tooth and human body artificial tooth.
Above-mentioned invisible false tooth, wherein, described thermoplastic elastomer resin is selected the Valplast resin material for use.
The denture base material that this utility model adopts has transparency height, high resiliency, thin and light characteristics, this makes unshowy but has the basal seat area of very strong bit function also to can be used on visibility region, cooperate with gingiva color, the natural gingiva color of patient can see through this material to be manifested, thereby do not see the existence of artificial tooth in appearance, have disguise.And this material has high resiliency and anti-broken folding, can be close to the neck edge and does not have foreign body sensation, and the material dead weight is little, and is very light, no matter still be sense organ from vision on, all have cryptomorphic effect.
The artificial tooth that this utility model provides does not use metal clasp and has disguise, natural, attractive in appearance, pass through the fusing mode physical connection between artificial tooth corona and the basal seat area, firm and tight, can be close to the neck edge and not have foreign body sensation, not stick to one's teeth, and the intensity height, can not produce metal allergy, as snug as a bug in a rug, light.And, the manufacture method of the invisible false tooth that this utility model provides, easy and simple to handle, cost is low.
Description of drawings
Fig. 1 is the structural representation of invisible false tooth of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is further described.
As shown in Figure 1, the invisible false tooth that this utility model provides comprises: basal seat area 11 and be arranged on artificial tooth corona 12 on the basal seat area 11, described basal seat area 11 also comprises the connecting portion 13 that connects the human teeth, and described invisible false tooth is fixedlyed connected with human teeth's buckle-type by this connecting portion 13; Described basal seat area 11 adopts thermoplastic resin material to make, described thermoplastic resin material can be transparent resin material, it also can be translucent material, when described thermoplastic resin was selected translucent resin material, the transparency of this material was according to the shade of patient's gingiva and difference.Described artificial tooth corona 12 is provided with some aperture (not shown), and described basal seat area 11 does not need metal clasp, described artificial tooth corona 12 with basal seat area 11 by the aperture on the artificial tooth corona 12 with the fusing mode physical bond, firmly and closely.
Described aperture is arranged on the downside of artificial tooth corona 12, and by the position of basal seat area 11 weldings covering.
Above-mentioned invisible false tooth wherein, connects between described some apertures, so that the artificial tooth corona firmly closely is connected more with basal seat area.
This utility model adopts the thermoplastic elastomer resin material as denture base material, this material has the transparency height, high resiliency and frivolous advantage, when high temperature, be molten into liquid state, the basal seat area model forming is filled in injection moulding, and is injected in the aperture of artificial tooth corona, during to be cooled solidifying, basal seat area and artificial tooth corona strike up partnership, firmly closely.Adopt this fusing mode physical connection between described basal seat area and the artificial tooth corona, not needing influences metal clasp attractive in appearance, has alleviated the burden to residual tooth, can not produce to stick to one's teeth and metal problem hypersensitive.
The preparation method of invisible false tooth comprises:
Step 1, adopt Gypsum Fibrosum to make the basal seat area mould: the artificial tooth corona is fixed on relevant position in the gypsum mold, and described basal seat area is to adopt paraffin to make, after the paraffin base completes, paraffin is removed, obtained having the gypsum mold of the shrinkage pool of basal seat area shape;
Step 2, valplast 110 resins are heated to 220 ℃～250 ℃, until melting fully for liquid, adopt the invisible false tooth machine that the valplast 110 resins pressurization of liquid state is injected in the gypsum mold of step 1 gained, make the shrinkage pool in its complete filling mould, and be injected in the small holes of artificial tooth corona, make basal seat area and the complete welding of artificial tooth corona;
Step 3 is cooled to room temperature, opens mould, removes Gypsum Fibrosum, obtains connecting firm artificial tooth.
During use, invisible false tooth is fixedlyed connected by the connecting portion buckle-type of invisible false tooth with the human teeth, convenient disassembly, flexible.
The invisible false tooth that this utility model provides, adopt thermoplastic elastomer resin material basal seat area and connect the artificial tooth corona by the welding mode, connect close and firm, be difficult for sticking to one's teeth, and because base material itself has transparency height, high resiliency, frivolous characteristics, invisible false tooth has nature attractive in appearance, and is light comfortable, is difficult for the advantage of broken folding.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
