Metal Umqhele ukubunjwa: izithombe, izibuyekezo, ukufakwa. Ukukhiqizwa metal imiqhele amazinyo

Metal imiqhele on the amazinyo zisekhona ethandwa, njengoba akukho okwamanje ephephile futhi namandla ngalezi zitho ungazange yasungulwa. imikhiqizo Zazinjalo kusukela ezikhathini zasendulo okhokho bethu, futhi namanje uqhubeke sisebenzele abantu ukuqina yabo. Nakuba ifomu e imiqhele akuyona ezikhanga kakhulu, kodwa intengo nekhwalithi zivumelana ngokoqobo.

Yini lena

Umqhele ukubunjwa isihloko metallic okuyinto Yenziwe Alloys ezahlukene titanium hromokobaltovogo metal, nickel-chromium, kanye nomklamo walo olubunjiwe ngokuphelele. The main isicelo endaweni yaleli ezihlukahlukene imiqhele - okufakelwa uhlobo namazinyo ukuhlafuna. Lokhu kungenxa abampofu ingxenye yabo yobuhle.

Umqhele (metal) kubhekwa isihloko ngokunembile olubunjiwe okuyinto Nokho ezahlukene umbala metallic, kodwa kakhulu ngokuqinile ehlezi umlomo. Okunjalo imiqhele - i choice omuhle eside amazinyo.

Izinzuzo imikhiqizo iyunithi-cast

Okubalulekile okunjalo a has eziningi eziwusizo, okuyilezi:

1. Uvalwe eseduze isakhiwo izinyo.
2. Ingabe zokuphepha (amazinyo ingangqubuzani futhi musa ninamathele).
3. Ezahlukene zemvelo ukuma yokwakheka.
4. Inani elincane kuqhathaniswa nezinye ontanga.
5. Akukona ukusula namazinyo eziphikisanayo.
6. Ngokuphawulekayo iyaqala ukuhlafuna ukusebenza.

Izizathu ukufaka

Ochwepheshe ukweluleka ukubeka metal imiqhele kuphela ezimweni ezithile:

• wabhubhisa abathandekayo namazinyo banesibopho ukuhlafuna;
• ingxenye Ngomhlathi we eziningi kakhulu bakhathale;
• izinyo is kulimala noma abalimele;
• amazinyo kukhona izimila.

Ukubeka umkhiqizo elinjalo, udinga okungenani izikhathi ezimbili ezizayo emuva wamazinyo-wezifo zamathambo. Okokuqala, udokotela ujwayelene radiographs temlomo emihlathini ke ukuqala ukwelashwa kwamazinyo ka caries, okuyinto izofakwa kusuka umqhele metal. Esendaweni lapho kokuphenduka kuhlelwe noma ukulungiselela, isuswe izinzwa.

Umqhele Metal: izinhlobo

Ngokuvamile, uma isiguli icela usizo wamazinyo ukubeka umqhele metal, yena inikezwa ezimbili ongakhetha, kuye ngokuthi indlela zokukhiqiza:

1. umkhiqizo Diecast. It ikhiqizwa at ukhonkolo ekhethekile bayobhaka kuhhavini. Lokhu umqhele libhekene izindonga awugqinsi, okuyinto kahle kuthinta ukuphila service. Yenziwe isisekelo (chromium Alloys, nickel, steel) futhi izinsimbi yizicukuthwane (platinum, palladium, igolide, isiliva) metal. Ngenxa imikhiqizo steel Umbala kuphela amazinyo lateral wokufakelwa kufihlwe phakathi nengxoxo. Basuke ngokufanele afanele ukuze wokufakelwa namazinyo posterior ngoba kungaba ukumelana imithwalo eside.
2. umqhele wanyathela kuyinto emikhonweni ejwayelekile, okuyinto iphucuziwe ne umshini ekhethekile ukunikeza umkhiqizo ukuma ofiselekayo.

Modeling yabalingisi imiqhele

umkhiqizo okunjalo kubhekwa enokwethenjelwa eyodwa sokwenziwa futhi efakwe kusuka ingxubevange ayibe-chrome. Umqhele (metal), steel cast has bokuphakama obungenakuphikwa - ayinayo solder amalunga omzimba, futhi lokhu kwenza kube eziqinile ikakhulukazi. It ihlanganiswa kahle izinyo grinded, singavumeli ingxube ukuhlakaza usimende kanye nokunciphisa amathuba okungena ekujuleni ngaphansi ukudla kwakhe. yokusebenza isikhathi - eminyakeni 15-20. Ukumodela yabalingisi imiqhele yokuhlala amaphuzu amaningana:

• ngomjovo we sokwenziwa;
• ukulungiselela izinyo (ikhishiwe ukusuka 0.2 kuya 0.6 mm izicubu);
• ukukhiqizwa wax cap Ithungelwe ngokusebenzisa;
• umhlobiso, fit kuyinto, wokucwebezelisa ebusweni insimbi;
• izifinyezo, kuhlanganise aphikisanayo namazinyo eduze.

Amasampula izihloko ezifana

Njengamanje, ehhovisi wamazinyo-wezifo zamathambo baba-cast metal imiqhele (impendulo ngazo iningi iziguli ungezwakala omuhle kuphela) ngezinhlobo eziningi:

1. Uncoated - imikhiqizo elula steel umbala.
2. Nge sputtering. Uma isiguli akuhambisani nalesiprofetho "ubuhle", nesifiso sakhe umqhele kungenziwa by sishaye, ulingisa igolide.
3. Camera. Icatshangelwe aesthetically olumnandi umkhiqizo, uphahlwe izitsha zobumba. Eceleni kwabo phambi embozwe ulwelwesi sobumba. Nokho, kufanele uqaphele kakhulu lapho ukudla, ngoba izitsha zobumba kungenziwa ukugunda.
4. Kuhlanganiswe. Uma lokhu wokufakelwa umqhele ingxenye embozwe zobumba, nabanye ukuthi kufihlwe lapho ukumamatheka pose ngaphandle ambozwe.

umqhele wanyathela

Lokufakelwa kwezitho ekhiqizwa emagobolondweni ifektri, anikeza ifomu kunesidingo. Imikhiqizo Amagobolondo nomzimba omncane, ngakho asikho isidingo ngoba inani elikhulu namazinyo by kwezicubu ukugaywa. Umqhele (metal) isethwe uma kungekho ukubhujiswa izimpande, futhi zigcinwe 1/3 izinyo. Ukuze ukukhiqizwa yayo asetshenziswa igolide noma insimbi engagqwali.

Ukudaleka kalula kuchazwe amanani aphansi hhayi kuphela, kanye nesikhathi sokuphila encane impahla. Igolide umqhele wanyathela eyenziwe ingxubevange, okuyinto ebangela u-90% igolide.

yokukhiqiza esiteji

Kunezigaba ezithile udala umqhele:

• nesineke umsebenzi ukhonkolo kokubili emihlathini ngoba akhombe umkhiqizo ukuba kwenziwe imizuzu engu-15 kwaze kwaba yilapho kokucindezelwa eluhlaza;
• Gypsum imakwe umugqa we sokwenziwa ukuze ingahambi sibanzi noma elincane;
• kulandele ukumodeliswa emakhilayoni, okuyinto isetshenziswa ebusweni usimende - ngaleyo ndlela, umqhele (metal) uthola ukuma yokwakheka;

• ku-besondele steel imodeli isitembu wadala, okuyinto ngenkani emikhonweni;
• wokushaya yangaphandle Kwenziwa usebenzisa cindezela isikulufa;
• isitembu zisuswe, futhi emaphethelweni umkhiqizo bafa nge sikelo ekhethekile.

Isikhathi ukukhiqizwa ngokuphindaphindiwe kokudubula, insimbi banda baba ngaphezu kuka ezingxabanweni uqine. Esikhathini sokwenziwa akufanele kube ukushayisana nokusasamba.

Izinkomba ukufakwa ishidi presswork metal

Ukufaka metal imiqhele kwenziwe:

• pre-wokufakelwa ingane izinyo ukuze ushintsho yayo njalo;
• ukulondoloza izinyo enempilo;
• njengoba esibaluleke kakhulu ukufakwa kwebhuloho ;
• uma izinyo is zilimale noma kabana caries ukuthi akunakwenzeka ukuba aqalise futhi uphawu.

Ukufakwa inqubo imiqhele

Lokhu senzakalo sivame ukwenzeka ngo 2 izigaba:

1. Ekuqaleni, lo mkhiqizo ibekwe okwesikhashana, ukuze udokotela abheke ukusabela izinyo.
2. Uma isiguli akusho esekhala ubuhlungu, ngesikhathi esilandelayo ukuvakashelwa umqhele isuswe, zihlanjululwa ngumuntu kwangaphambilini kanye usimende setha kabusha, kodwa nge-zinc-phosphate noma ingilazi ionomer.

Uma umphumela ukufakwa lokuqala bathole ukuthi umqhele metal (isithombe kukhonjisiwe ngezansi) kubangela ubuhlungu nesineke, bese kuzosuswa futhi ngeke ukucubungula futhi.

umkhiqizo Yini okufanele afakwe kahle

Iqiniso kukhiqizwa futhi olunikezwe umqhele:

• igobolondo kanzima adjoins izinyo;
• It has a bushelelezi, ifomu iphucuziwe;
• sags periodontal e ikhefu ka 0.2 mm;
• eveza ukuma yokwakheka izinyo izinyo lomhlathi;
• e emazinyweni eduze futhi eziphikisayo.

Izimo ukufaka

hhayi Kunconywa masosha abeka metal Kwezinye izimo, uma kukhona:

• bruxism;
• komzimba yokubakhona steel;
• malocclusion dentition;
• umonakalo lizwakale izinyo ophilayo;
• eziyinkimbinkimbi ngenxa sobuhle bayo abampofu wokufakelwa namazinyo anterior.

Yimuphi umonakalo has umqhele metal

Ezimweni ezithile, lo mkhiqizo kungadala umonakalo:

1. Ngenxa ukufakwa kwalo zingavela kukagesi syndrome. Lokhu kungenxa ukusetshenziswa Alloys eziningana ngokudala isakhiwo zokufakelwa. Ukuxuba ngezinto ezahlukene kuholela ekwakhekeni wamanje kukagesi. Kukhona ikhanda elibuhlungu, ukuvuvukala, ezinye izifo, ukunambitheka metallic, ukuqwasha, evutha emlonyeni.
2. Umqhele (extruded) asisho ukukhiqiza ku ukhonkolo ahlukene, ngakho-ke ukuba kuhlalwe ukululama ezanele nemisebenzi izinyo ophilayo.
3. Umkhiqizo akuyona eduze eseduze izinyo, ukudala Intermedia izindonga mafutha anciphisa isikhala esingaphakathi, okuyinto zingene okusalile. Ngakho-ke, kungase beze ngaphansi ukubola inyama ephilile.
4. Umqhele ukubunjwa kuyahluka conductivity enhle ezishisayo. Uma usufakwe izinyo nedepulpirovanny, ngesikhathi yokwamukela ukudla okushisayo ingavela emizweni ezingezinhle.

ubuchwepheshe Ageless

Ukukhiqizwa metal imiqhele kuyinto "phakade abasha" ubuchwepheshe nekhulu leminyaka elidlule, okuyinto cishe olwesimanje eminyakeni yamuva. Kanye ezinye izindlela zanamuhla futhi imfashini sokwenziwa unomphela, ehlala enjengoba ethandwa. Lokhu akusona isimanga, ngoba isizathu esiyinhloko lokufaneleka ezinjalo - ongaphakeme izindleko sokwenziwa ngamandla aphezulu.
