Yintoni ofakwe? Iintlobo ofakwe kwi wamazinyo

Ayizizo zonke izigulane kwikliniki yamazinyo bambuza ntoni bokumisa amazinyo eziphathekayo. Kodwa le into iba nefuthe ngqo kuyo kuya kude kube nini na ngetywina. Ukongeza, uhlobo lwezinto kuxhomekeke impilo izinyo kwakunye kumgangatho nobunzima inkqubo zonyango. Namhlanje siye sithethe malunga ukukhetha nendlela ezisebenza ngayo ezi zinto. Iintlobo lamatywina, amalungelo abo kunye nezingeloncedo nabo ngazo kweli nqaku.

iimfuneko jikelele kwiziseko amazinyo

Okokuqala sibone ukuba yintoni kanye le ngokugcwalisa bamazinyo? Le izinto zonyango, apho viscosity kunye plasticity, nto ngexesha okanye ngenxa yeemeko yangaphandle Ukuguqulwa kolwelo em- izinyo.

Kukho uluhlu ezifunekayo kuzo zonke iintlobo zamanzi:

1. Ukhuseleko. Ezi zibonelelo ziya kuthi zingqinelane nemigangatho zisempilweni lusekiwe.
2. Insolubility.
3. Ukuphikelela - uphawu akufunekanga zicinywe okanye zinciphise umthamo.
4. Ukuba ekuqiniseni ngexeshana elifutshane.
5. Izinto ayikwazi ukutshintsha umbala, umbala.
6. Strength.

Iintlobo zokwakha kwiziseko izinyo

Xa kwezamazinyo mihla usebenzisa izinto ezahlukeneyo imveliso kwiziseko zamazinyo. Ngamnye kubo bobabini ezilungileyo nezingalunganga. Ezinye izinto woyibingelela kwiikliniki ezamahala zoluntu, ngoxa abanye ngexabiso eliphezulu. Ngoko ke, ziziphi iintlobo eziphambili amatywina? Okwangoku, kukho izinto ezintathu:

• chemical;
• photopolymeric;
• ixesha.

uhlobo ngalunye luquka iintlobo zeHPV zingonobangela, kuxhomekeke izinto ifakiwe ekwakhiweni izixhobo izinyo ukugcwaliswa.

amatywina isamente

Ezi ntlobo ukuwavala amazinyo walungisa ngokuqhelekileyo kwento angumgubo kunye engamanzi acid. Ngenxa yoko wokuxuba, yokusabela imichiza, ngexesha apho umxube paste-ezifana kwasekwa kokuba ipropati lukhuni ngexesha lekhefu elithile.

amatywina Cement, ke, nazo yahlulwe subgroups kuxhomekeke izinto ezikhoyo ekwakhiweni, ngolu hlobo lulandelayo:

• izinc ne phosphate;
• silicates;
• silicates phosphate;
• polycarbonates;
• ionomers glass.

Lamatywina ezine zokuqala zenyathi imichiza. Kwaye lo wokugqibela lukhuni kokubini acid kunye amaza okukhanya.

Sinakho ofakwe iimpawu zesamente:

1. iindleko Low.
2. Akukho mfuneko yokusebenzisa ngexesha ngokugcwalisa yezixhobo ezizodwa.
3. Ilula kwimizobo izinto lenkqubo yofako.

Yiba ofakwe ezinjalo ethile ezibalulekileyo:

• ngokukhawuleza balahlekelwe isimo sabo, umthamo,
• Kufuneka ixesha elide ixesha elithathiweyo ukugqiba Ukuqinisa;
• ngexesha okanye phantsi kweempembelelo iimeko zangaphandle kulula ukuba ukuzivula, ziba;
• xa ephethe kakuhle ngaphandle inkqubo ngokundimisela sibizwa kunokwenzeka eziqhotyoshelwe izinyo uphilile;
• Oku akuthethi ukukhusela ngokuchasene kwakhona kokuhluma-okanye andise yidityaniso;
• ityhefu.

Ezi neengxaki kufuneka ibe ithile enoba kukancinane okanye zonke ukuwavala zenyathi zesamente, iglasi ionomers ngaphandle. Le nto sisetyenziswa ngokubanzi amayeza mihla, kuquka kwiiklinikhi zabucala. Le uphawu awunatyhefu. Iqulethe shintsha fluoride ekhusela izinyo ukusuka ukusasazeka ngakumbi kwiindawo carious. Ngaphezu koko, izinto hayi lizele kuphela isithuba izinyo emzimbeni, kodwa uza wayesebenzisa kwindawo yokusabela michiza. Ngokusebenzisa le nkqubo, ukuwavala iglasi ionomer ihlala ixesha elide.

izinto zalo

Zeziphi iintlobo ukuwavala zesinyithi yamazinyo? Oku kubizwa ngokuba yi-amalgam - nezisombululo ezisekelwe iintsimbi banayo impahla ephilisa. Kukho isiliva, igolide nobhedu.

Metal seal babe namandla eliphezulu, azikho upheliswe ngamathe. Ngaphandle koku, xa bamazinyo mihla ezinjalo izinto phantse asisetyenziswa konke. Zintoni bobubi? Ezininzi kubo:

• ngokuba ukufakelwa ezinjalo lamatywina ifuna izixhobo ezikhethekileyo zobungcali, engekho kwisibhedlele ngasinye;
• metal Ukuguqulwa kolwelo kancinane;
• uphawu kwahluka kakhulu ukusuka umbala izinyo zendalo;
• ukuze aphuhlise yidityaniso;
• badla kwabhalwa amatyala nangenjinana, incasa sisinyithi emlonyeni.

ofakwe zeplastiki

Abo kusetyenziswa kwiziseko zamazinyo mihla? Iintlobo zamanzi, kukho ezahlukeneyo, ngoko ugqirha ukhetha abo ukuba enze umsebenzi wabo kakhulu ngokufanelekileyo kwimeko ethile. Kodwa ngoku iingcali izinto zeplastiki mancinane amathuba ukuncoma izigulane zabo. Nangona kwiminyaka nje embalwa edlulileyo, satywina onjalo enye indlela ezintsha metal. Kutheni iplastiki Abawugcinanga lweFIFA yalo phezulu phakathi izinto ezithandwayo ukuba ufakelo kwiziseko zamazinyo?

Eyona nto kukuba isisombululo enjalo kususwa ngokukhawuleza wahlehla ngumqulu, litshintsha umbala. Ukongeza, iintini zeplastiki sisoloko sisenza izigulane abuthethe negazi ezifana irhashalala, ububomvu emlonyeni. Ukongeza, ezi zinto ayityhefu.

zisasilela

uhlobo Common of ukuwavala ezi zisasilela. ahlelwe ubandakanya zombini izinto eziphilayo nezingaphiliyo. Eqina izinto labalandeli phantsi kweempembelelo inkqubo yemichiza, kwakunye yelanga.

zisasilela Ukusekwa ifuna ulwazi lobugcisa abaziingcali ukulungiselela izinyo yale nkqubo. Ekubeni waphula naziphi na iinkqubo umgangatho ukuqina itywina liyehla.

Uncedo ukuqina bubukho yesixhobo ebanzi yezinto evumela ukuba enze iinkqubo zamazinyo kunye iinjongo zobugcisa.

seal ukukhanya

Amaxesha amaninzi, ngenxa kwiintengiso amaxwebhu olunokubakho abathengi kugqirha wamazinyo okokuqala wazana sexesha ezifana photopolymers. Yintoni ngokwenene? Yinto elula kakhulu - yeyona zisasilela efanayo okanye ionomers iglasi ukuba zifakwa kunye isibane UV okhethekileyo. Ezi ntlobo ukuwavala xa woogqirha bamazinyo zisetyenziswa rhoqo ngaphezu kwabanye.

Namhlanje kunzima ukufumana ekliniki, nto leyo wanikela inkonzo ezifana photopolymerization. Yintoni, ke, banamalungelo zezi ntlobo ukuwavala amazinyo?

1. Strength.
2. Plasticity.
3. Sobuhle.
4. Easy ukufaka.
5. iziphumo Quick.
6. Ukungabikho kwe izinto eziyityhefu ekwakhiweni.

Kunye photopolymers bayithwala ukubuyiselwa kwamazinyo ngaphambili. iipropati Amanqaku ukuvumela "sculpt" imilo echanekileyo ezintle, ebezikuyo ebelapha ukulungisa isiphumo nge yelanga. Ngoko ke, zonke go mnye, ungenza iqalise le nkqubo amazinyo eziliqela.

Kodwa nantsi amazinyo elide ngale ndlela kunzima kakhulu ukuba bazalise - yinto nje lula ukufikelela isibane kwindawo wacela kwisisu ngomlomo.

mathiriyeli

Ngokufuthi, wamazinyo kuyimfuneko ukufaka ukuzaliswa yethutyana iinjongo zonyango. neemfuneko izinto ezinjalo ephantsi it ukuvala umngxuma izinyo ixesha iintsuku eziliqela ngeveki, emva koko satywina kunokuba lula ukuba ukususa.

ofakwe lwethutyana ivale kwaye ulala ngokwaneleyo, uhlale, ngoko musa ukubeka ixesha elide.

Amaxesha amaninzi, izinto ezifana ziyongezwa eziyobisi. Ngoko ke isenzeko akumnandi incasa okanye emlonyeni livumba kunokwenzeka.

Iintlobo ofakwe yethutyana yile ilandelayo:

• uxilongo;
• bekujongiwe unyango enyangayo;
• seals zokwenziwa.

Yaye yintoni amazinyo ngophawu abantwana?

Abazali abaninzi musa nokuba ucinga ngayo loo mntwana, kwakunye umntu omdala, kufuneka wamazinyo kuhlolwa. Kutheni ngayo amazinyo xa kunjalo kungekudala iwe? Enyanisweni, kuxhomekeke kwi imeko yempilo ubisi kwamazinyo. Ngoko ke, abantwana kufuneka etywiniweyo amazinyo ngaxeshanye, kamsinya nje naziphi na izinto ezibonisa ukuba le nkqubo.

Kulo mzekelo, kubalulekile ukuba ukhethe izinto ekhuselekileyo. Kwiziseko ukusetyenziswa amazinyo ezingabantwana eziqulathe fluorine (ukuthintela ukwakheka ngakumbi yidityaniso). kulula kakhulu ukuba ukusebenzisa izixhobo ukuba lukhuni phantsi ukukhanya yelanga - xa unyango abantwana abaninzi ngokufuthi zisetyenziswa ezinjalo amatywina. Iintlobo zamanzi, leyo ngoku ithandwa kakhulu kwi amazinyo abantwana, iglasi ionomer thaca kunye zisasilela.

ofakwe ezinemibala abantwana: ntoni na?

A ezintsha kwi amazinyo, intsimbi elinombala ukuwavala amazinyo abantwana. Iintlobo zezixhobo azimisele ngumvelisi.

Bright, ezifana yokudlala, ukuwavala kubangela umdla wokwenene, oku kunciphisa ukumoyika kugqirha wamazinyo ebantwaneni.

Ezo zincedisi zokufunda kwakhona une amandla aphezulu. Kwiimeko ezininzi, it ihlala ebantwaneni ukuya ukuba baguqukile kwamazinyo. Ngaphandle ofakwe ezinemibala ezi ibengezela kakuhle, oko zeplastiki, kunye nokufakwa kwayo ethatha ixesha elifutshane.

Yintoni ukukhetha kwiziseko? Iintlobo zamanzi ezifunekayo kwityala yonyango ethile kufuneka siphakamise ingcali kuphela. Ekubeni kufuneka awuqeqeshelweyo ukuhlola imeko, ezahlukeneyo izinto kwaye amisele ukuba uhlobo material na izityalo le isigulane ethile.
