Description
Technical field
The present invention relates to a kind of hump nose material and preparation method thereof.
Background technology
Cosmetic plastic surgery is medical science applied important component part.Along with the improvement of goods and materials life, people are more and more high to the requirement of U.S..No matter be Chinese or foreigner, it is quite a lot that nose shape does not meet aesthstic standard person.Therefore, to correct the augmentation rhinoplasty of the bad mode of appearance of nose, just to become the hot topic operation that is only second to double-fold eyelid operation, occupy second of plastic and aesthetic surgery.Selected clinically augmentation rhinoplasty filler has two big classes, the one, transplanted tissue, the 2nd, tissue substitute at present.Transplanted tissue comprises: 1. the tissue of nose itself, and as nasal septal cartilage, nasal alar cartilage lateral crus, lateral nasal cartilage tissue etc.But these organize very limited, are only applicable to the filling of bridge of the nose than dolly dimple.2. cartilaginous tissue beyond the nose, as costicartilage, ilium, rib, tibia, olecroanon, femoral bone tuberosity, cranium etc., not only the graft area wound is bigger for these osseous tissues, and the yielding bridge of the nose bending that causes of costicartilage, all the other osseous tissue filling nose bottoms are comparatively stiff, are subjected to the wound easy fracture.Tissue substitute: the more tissue substitute of clinical practice is firm silicone rubber goods and hydroxy-apatite stone manufacture at present.The physicochemical property of firm silicone rubber is stable, but long preservation in vivo, and is pliable and tough and tool elasticity is easy to sculpture be shaped, but there is rejection in this material, and psychopathia can appear in the minority person of being planted.The hydroxy-apatite stone manufacture is a kind of non-absorbent bioceramic, the contained mineral of its chemical constituent and vertebrate tooth skeleton is extremely similar, this material has the biocompatibility of height, with body tissue good affinity is arranged, nontoxic, nonirritant, no rejection, no catabiosis, not sensitization, carcinogenic.But hydroxyapatite can not be shaped before art, can only rub proportionately required form with pointing extruding gently in inserting process, need certain experience, and the time of implantation after coagulation is long, and yielding when being subjected to external force, the graininess hydroxyapatite moves in the easy migration of intranasal in addition.
Summary of the invention
On-deformable hump nose material and preparation method thereof when the present invention provides a kind of convenience of drawing materials, wound is little and is subjected to external force at the problems referred to above exactly.
Technical scheme provided by the invention is: a kind of hump nose material, made by purgation: the tooth that will break away from human body earlier soaks demineralization in concentration is the hydrochloric acid of 5%～20% (percent by volume), then the tooth body is cut into foliaceous or earlier the tooth body is cut into foliaceous and soak demineralization again in hydrochloric acid; Foliaceous dental tissue after the demineralization is connected into nose augmentation prosthesis with the titanium silk; By mask nose augmentation prosthesis is ground into the individual character prosthese at last.
The optional human body third molar of using of above-mentioned tooth.Be preferably from the body tooth.
The preparation method of above-mentioned hump nose material is earlier soaked demineralization with the tooth that breaks away from human body in concentration is the hydrochloric acid of 5%～20% (percent by volume), then the tooth body is cut into foliaceous or earlier the tooth body is cut into foliaceous and soak demineralization again in hydrochloric acid; Foliaceous dental tissue after the demineralization is connected into nose augmentation prosthesis with the titanium silk; By mask nose augmentation prosthesis is ground furnishing individual character prosthese at last.
Above-mentioned demineralization is carried out according to the following steps, earlier with tooth or cut into foliated dental tissue and in the hydrochloric acid of 10%～20% (percent by volume), soaks demineralization 4～12 hours, immersion demineralization 4～12 hours in the hydrochloric acid of 5%～10% (percent by volume) then.
The present invention is a main material with people's tooth, draws materials conveniently, wound is little or do not have wound (as the tooth that comes off automatically), and the tooth after decalcification is handled can be moulding arbitrarily as required, and not yielding when being subjected to external force.The present invention has the better tissues compatibility, with surrounding tissue good affinity is arranged, and is difficult for after the transplanting being absorbed, to not having influence for form, the function in district.
The specific embodiment
Hump nose material of the present invention can be made by purgation: the tooth that will break away from human body earlier soaks demineralization in concentration is the hydrochloric acid of 5～20% (percents by volume), with cuing open the tooth machine tooth body is cut into foliaceous then, or earlier the tooth body is cut into foliaceous and in hydrochloric acid, soak demineralization again: the foliaceous dental tissue after the demineralization is connected into nose augmentation prosthesis by the parameter that facial delivery obtains with the titanium silk; Nose augmentation prosthesis is ground the individual character prosthese that becomes to conform with face beauty treatment angle by mask at last.
Because of tissue of tooth similar in appearance to osseous tissue, but than osseous tissue degree of calcification height and hard, be difficult for mouldingly, have only after appropriate demineralization, just can reach the requirement of making nose augmentation prosthesis.The demineralization of tooth body also has following advantage: reduce hardness, in order to prosthese plasticity; Alleviate transplant weight, anti-falling stop sense; The shape depression appears nibbling in demineralization tooth surface, and favourable transplant surrounding tissue is adhered to maintenance etc.
Human body third molar or the just abnormal premolars of extracting are selected in above-mentioned tooth suggestion for use; The human body third molar is in the organ of mastication of catagen phase, be positioned at the end of dental arch, the masticatory function of being born is little, often how need pull out because of misplace eruption or impaction, do not influence masticatory function and local form after pulling out, utilize these depleted tissue treatment saddle nose deformities, have the effect that turns waste into wealth.
With upper teeth be preferably the augmentation rhinoplasty object from the body tooth.
