Yiziphi ofakwe? Izinhlobo ofakwe amazinyo

Akubona bonke iziguli yamazinyo umbuza iziphi izinto bokumisa amazinyo. Kodwa lokhu isici kunomthelela oqonde ngqo esingakanani kuyogcina uphawu. Ngaphezu kwalokho, uhlobo impahla incike impilo izinyo kanye ezingeni layo obulukhuni inqubo yokwelashwa. Namuhla sikhuluma kanjani ukukhetha indaba for ofakwe. Izinhlobo kunezimvu zamanzi, amathuba abo kanye nebubi nazo okuxoxwe ngazo kulesi sihloko.

Izidingo Jikelele I-filling amazinyo

Okokuqala zama ukuthola ukuthi yiziphi ngempela ukugcwalisa amazinyo? Lokhu kwaziswa wezokwelapha, lapho viscosity futhi plasticity, okuyinto ngesikhathi noma ngenxa izici zangaphandle osemanzi kule ingaphakathi izinyo.

Kukhona uhlu izimfuneko zonke izinhlobo lwezimpawu:

1. Security. Indaba kufanele bavumelane esungulwe kwezinkambiso yokuhlanzeka.
2. Insolubility.
3. Ukuphikelela - uphawu akufanele ukusulwa noma zinciphise ivolumu.
4. Kufanele yokuzigxilisa ngesikhathi esifushane.
5. Material Awukwazi ukushintsha umbala, ezinemibala.
6. Amandla.

Izinhlobo izinto ngezinyo ofakwe

Amazinyo yesimanje isebenzisa izinto ezahlukene ukwenziwa filling amazinyo. Ngamunye wabo bobabili ngebuhle nebubi. Ezinye izinto unikele kule khulula emitholampilo kahulumeni, kanti abanye kufanele izindleko kuqhathaniswa eliphezulu. Ngakho, iziphi izinhlobo ezinkulu zamanzi? Okwamanje, kunezinhlobo ezintathu:

• chemical;
• photopolymeric;
• isikhathi.

Ngalunye oluphilayo zakwazi kuhlanganisa subtypes, kuncike izinto afakwe indlela yokwakheka impahla izinyo ukugcwaliswa.

usimende lwezimpawu

Lezi zinhlobo ofakwe amazinyo okulungiselelwe ngokuvamile into powdery kanye ketshezi acid. Ngenxa yalokho yokuhlanganisa, ukusabela zamakhemikhali, phakathi kwesikhathi lapho ingxube nokunamathisela-like kwamiswa kokuba impahla lukhuni ngesikhathi esithile sesikhathi.

Usimende zamanzi, zona futhi ihlukaniswe yaba subgroups kuncike izinto ekhona Ukwakheka, njengoba kulandela:

• zinc kanye phosphate;
• silicates;
• silicates nama-phosphate;
• polycarbonates;
• ingilazi ionomers.

Eyokuqala lwezimpawu ezine zenyathi zamakhemikhali. Futhi wesibili bangase lukhuni kokubili by acid sijikijelwa amagagasi ukukhanya.

Ifa enjalo izimfanelo usimende ofakwe:

1. eziphansi.
2. Asikho isidingo ukusebenzisa ngesikhathi ngokugcwalisa izinsimbi ezikhethekile.
3. Ukwenza Izinto Zibe Lula ubuciko ukufakwa inqubo impahla.

Have ofakwe abanjalo bangabaphostoli nemiphumela ethile engathandeki abalulekile:

• ngokushesha ukulahlekelwa isimo sabo, ivolumu,
• Badinga isikhathi eside ukuqeda solidification;
• ne isikhathi noma ngaphansi kwethonya izici zangaphandle kulula ukwambula, sidilike;
• uma kungenjalo kahle yokufeza inqubo yokumisa uphawu kungenzeka okuphiniwe izinyo enempilo;
• Akukona ukuvikela kabusha ukuvela noma Lokusakaza caries;
• ezinobuthi.

Lezi yokuntula kufanele ngokwezinga elikhulu noma elincane zonke ofakwe zenyathi usimende, ingilazi ionomers ngaphandle. Le nto kabanzi kwezokwelapha zanamuhla, kuhlanganise emitholampilo yangasese. Lolu hlamvu akuyona anobuthi. Iqukethe inkinobho fluoride evikela izinyo kusukela ukusabalala kwaleso izindawo carious. Ngaphezu kwalokho, i-ezibonakalayo kuphela igcwalisa esikhaleni izinyo ngokwenyama, kodwa futhi iza koqweqwe lwawo e ukusabela zamakhemikhali. Ngokusebenzisa le nqubo, ingilazi ionomer ofakwe ihlala isikhathi eside.

izinto metallic

Yiziphi izinhlobo metal filling amazinyo? Lokhu okuthiwa ziyinhlanganisela - izixazululo esekelwe izinsimbi ezithinta impahla sokwelapha. Kukhona isiliva, negolide nethusi.

Metal lwezimpawu babe namandla high, kungukuthi yahlakazeka ngu ngamathe. Naphezu kwakho konke lokhu, amazinyo yesimanje izinto ezinjalo cishe akazange asebenzise. Yiziphi bokwenza? Eziningi kuzo:

• ukufakwa seal ezifana zidinga imishini ekhethekile professional, engesiyo esibhedlela ngasinye;
• metal osemanzi kancane;
• uphawu sihluke kakhulu umbala izinyo yemvelo;
• angagcina caries;
• ngokuvamile eqoshiwe amacala ukuluma, ukunambitheka metallic emlonyeni.

ofakwe plastic

Labo elisetshenziswa ofakwe yesimanje wamazinyo? Izinhlobo kunezimvu zamanzi, kunezinhlobo ezahlukene, ngakho udokotela ekhetha yibo enze umsebenzi wabo kakhulu ngempumelelo ecaleni ethize. Kodwa manje izinto plastic Ochwepheshe mancane amathuba ukuncoma iziguli zabo. Nakuba eminyakeni embalwa edlule, uphawu ezinjalo kuba enye innovative ensimbini. Kungani plastic awukugcinanga simo yaso ephezulu phakathi izinto ezithandwayo ukufakwa filling amazinyo?

Into wukuthi ikhambi elinjalo kususwa ngokushesha unciphe emqulwini, eshintsha umbala. Ngaphezu kwalokho, izimvu zamanzi plastic ngokuvamile kubangela iziguli liphinyiselwe komzimba ezifana nokuqubuka, ububomvu emlonyeni. Ngaphezu kwalokho, lezi zinto anobuthi.

inhlanganisela

uhlobo ezivamile ofakwe kukhona inhlanganisela. Ukwakheka kwazo ngokwama-kufaka kokubili izinto eziphilayo futhi wezinto ezingaphili. Eqina impahla esiyinhlanganisela ngaphansi kwethonya yezinqubo zamakhemikhali, kanye emisebeni ultraviolet.

Ekwakhiweni zezinhlanganisela kudinga Uchwepheshe ulwazi ubuchwepheshe ukulungiswa izinyo le nqubo. Njengoba ayephuli iyiphi izinqubo ukuqina kophawu ancipha kakhulu.

Inzuzo undoubted kuyinto ukutholakala palette ebanzi izinto elikuvumela ukuba enze izinqubo zamazinyo kanye yobuhle.

seal ukukhanya

Ngokuvamile, ngenxa imibhalo yokuthengisa amakhasimende ngisabone yamazinyo okokuqala bajwayelane a eside ezifana photopolymers. Kuyini ngempela? Kulula kabi - kungcono inhlanganisela efanayo noma ingilazi ionomers efakwe nge UV isibani ekhethekile. Lezi zinhlobo ofakwe amazinyo asetshenziswa njalo kunabanye.

Namuhla kunzima ukuthola umtholampilo, okungasekelwe ahlinzekwa isevisi ezifana photopolymerization. Khona-ke, ube izinzuzo zalezi zinhlobo ofakwe amazinyo?

1. Amandla.
2. Plasticity.
3. Aesthetics.
4. Ifakeka.
5. Imiphumela esheshayo.
6. Ukungabi bikho ezinobuthi ekwakhiweni.

Nge photopolymers eyenziwa nokubuyiselwa amazinyo angaphambili. izakhiwo Material uvumele "sculpt" ijamo lesifanele enhle whereupon nabuhlungu silungise yi nge emisebeni yelanga. Ngakho, bonke ngesikhathi esisodwa, ungakwazi afeze inqubo on amazinyo eziningana.

Kodwa nakhu amazinyo eside ngale ndlela kunzima ngempela ukugcwalisa - akunakwenzeka ukufinyelela isibane endaweni wayefisa ngalo ingaphakathi ngomlomo.

mathiriyeli

Ngokuvamile, udokotela wamazinyo kuyadingeka ukuze ufake ukugcwaliswa yesikhashana ngenhloso zokwelapha. izimfuneko ezinjalo ezibonakalayo ongaphakeme: it has ukuvala imbobo ezinyweni isikhathi izinsuku ezimbalwa ngesonto, ngemva kwalokho kophawu kungaba lula ukususa.

ofakwe lesikhashana crack bese ulala ngokwanele, hlala, ngakho musa setha isikhathi esijana.

Ngokuvamile, izinto ezifana kunezelwa izidakamizwa. Ngakho-ke akuyona nesenzakalo okungaba khona kohlelo ezingemnandi ukunambitheka noma umlomo iphunga.

Izinhlobo ofakwe yesikhashana zimi kanje:

• ukuhlola;
• okuhloswe for yokwelapha;
• seal emkhakheni wezitho zokwenziwa.

Futhi lokho namazinyo uyivale izingane?

Abazali abaningi musa noma ucabange ukuthi ingane, kanye omdala, udinga isimiso ukuhlolwa udokotela wamazinyo. Kungani aphathe amazinyo uma namanje basheshe fall out? Empeleni, kuxhomeke ekutheni isimo unomphela ubisi amazinyo impilo. Ngakho-ke, izingane kudingeka namazinyo uphawu ngesikhathi esisodwa, ngokushesha nje izinkomba salokhu inqubo.

Kulokhu, kubalulekile ukukhetha izinto eziphephile. Ngo ezingane amazinyo ukusetshenziswa ofakwe equkethe sasekhaya (ukuvimbela ukwakheka obengeziwe caries zamazinyo). lula kakhulu ukusebenzisa izinto lukhuni ngaphansi kwe-ultraviolet - ekwelapheni izingane kuvame kakhulu ukuba kusetshenziswe lwezimpawu enjalo. Izinhlobo kunezimvu zamanzi, okuyinto manje ethandwa kakhulu umkhuba yamazinyo zezingane, ingilazi ionomer obubekwe ngaphambili futhi inhlanganisela.

ofakwe ezinemibala izingane: kuyini?

A eseyintsha umkhuba yamazinyo, steel ezinemibala filling amazinyo zezingane. Izinhlobo izinto zinqunywa ngumkhiqizi.

Bright, efana plasticine, ofakwe kubangele isithakazelo esiqotho, ngaleyo ndlela sinciphise ukwesaba nodokotela wamazinyo izingane.

Okubalulekile okunjalo Ubuye amandla aphezulu. Ezimweni eziningi, kuthatha ezinganeni kuze kube ushintsho amazinyo. Ngaphandle ofakwe ezinemibala kahle emihle, kuba epulasitiki kanye ukufakwa yayo kuthatha isikhathi esifushane.

Yini ukukhetha ofakwe? Izinhlobo lwezimpawu edingekayo endabeni ethile yezokwelapha kufanele bancome uchwepheshe kuphela. Njengoba udinga efanele ukuhlola isimo, ezahlukahlukene futhi ukunquma onjani impahla kangcono lokhu nesineke ethile.
