Ukwahlukana Kokuphakathi KweSiliva, Igolide, I-Ceramic nokuningi
Ukwelapha indawo , indawo yokubola ngezinyo, kuyingxenye evamile yokunakekelwa kwamazinyo. Okokuqala, udokotela wamazinyo uhlanza ingxenye yezinyo ezithintekayo, eshiya imbobo noma isikhala esingenalutho. Khona-ke uzogcwalisa leso sikhala ukuze aphume ngisho nendawo yezinyo ukuze "azizwe" emlonyeni futhi avikelwe ekuhloleni okuqhubekayo.
Kunezinhlobo ezinhlanu zezinto ezivame ukusetshenziselwa ukugcwalisa isikhala lapho isikhumba susiwe khona.
Uma udinga ukugcwaliswa, nansi ulwazi oluwusizo mayelana nezinhlobo ezahlukene. Ngeke ube nokuzikhethela njalo ngohlobo lokugcwalisa okudingayo, kodwa uma wenza kanjalo, kuyasiza ukwazi izinzuzo nezingozi zomuntu ngamunye.
Ukugcwaliswa kwe-Amalgam yesiliva
Lona uhlobo olwaziwa kakhulu lokugcwalisa. I-amalgam yesiliva akuyona nje isiliva-ingumxube wamaminerali angama-50% esiliva, tin, zinc, nethusi, namaphesenti angu-50 mercury. Kuyinto ethandwayo yokuzigcwalisa phakathi kwazinyo zamazinyo ngoba inamandla, ihlala isikhathi eside, futhi ayinayo imali. I-typical silver amalgam yokugcwalisa ingahlala iminyaka engu-15 noma ngaphezulu. I-amalgam yesiliva nayo ilula kakhulu ukuba udokotela wamazinyo afinyelele emgodini futhi akukho ukukhathazeka okungase kungcoliswe igazi noma umathe.
I-amalgam yesiliva inezinkinga. Akuyona into ejabulisayo, ngakho-ke akuyona into enhle ezinyoweni ezibonakala kakhulu. Lezi zinto nazo zinganweba futhi zenze isivumelwano phakathi kwesikhathi, okwenza izinyo ziqhekeke.
Lezi ziguquko nazo zingadala izikhala phakathi kokugcwaliswa kanye nezinyo ukudla okubangelwa yiwo ukudla kanye nama-bacteria, okuvumela ukuba kube nemigodi emisha.
I-mercury e-amalgam yesiliva iphikisana, kodwa ngokusho kwe-American Dental Academy kanye ne-US Food and Drug Administration, ucwaningo luye lwabonisa ukuthi i-amalgam yesiliva yokugcwalisa iphephile.
Ukugcwaliswa Okuhlanganisiwe
Ukugcwaliswa okuhlanganisiwe kwenziwa nge-resin ne-plastiki impahla efakwa emgodini ngenkathi ithambile, bese inzima ngokukhanya okuluhlaza okwesibhakabhaka okuphilisa. Kuyinto ethandwa kakhulu ngoba ingalinganiswa nombala emthunzini wamazinyo omuntu akhona, ngakho akucaci njengokugcwalisa i-amalgam yesiliva. Ngesikhathi esifanayo, noma kunjalo, ukugcwaliswa okuhlanganisiwe akuhlali isikhathi eside nje kwezinye izinhlobo. Ngokujwayelekile badinga ukushintshwa njalo njalo eminyakeni emihlanu noma ngaphezulu futhi banomvuzo kunesiliva.
Ukugcwaliswa kwe-Ceramic
Lezi zenziwe nge-porcelain futhi zombili zihlala ziqinile futhi zikhangisa kahle. Ukugcwaliswa kwe-Ceramic kuyabiza kunezinye izinhlobo, kodwa zinemibala enozinyo futhi ziphikisana kakhulu nokukhwabanisa nokuqeda ukwedlula uhlaka lwezinhlanganisela. Ukungahambi kahle kokusebenzisa i-ceramic esikhundleni sokuhlanganiswa ukuthi kungcono kakhulu futhi ngakho-ke kudinga ukukhudlwana ukuyivimbela ekuphukeni. Lokhu kusho ukuthi indawo ezinyo kumele yenziwe ibe yikhulu ngakho kukhona indawo yokwengeziwe. Lezi zindlela zokubuyiselwa nge-ceramic ngokuvamile zibizwa ngokuthi ama-inlays noma ama-onlays.
Ukugcwaliswa kwe-Ionomer ye-Glass
Lezi zigcwalisi ze-glass-and-acrylic zihle kubantwana abanamazinyo abo asashintshayo. Zihlala zingaphansi kweminyaka emihlanu kodwa zikhulule i- fluoride , engasiza ekuvikeleni izinyo ekukhuleni okuqhubekayo.
Kodwa-ke, zibuthakathaka kakhulu kunezinhlayiyana ze-resin futhi kungenzeka ukuthi ziqhekeke noma ziphele. Ingilazi yendabuko ye-ionomere ayifani nombala wezinyo njengoba ngokunjalo njenge-resin eyakhiwe.
Ukugcwaliswa kwegolide
Ngeke kusimangaze ukwazi ukuthi ukugcwalisa igolide kuyabiza futhi akuvamile kakhulu. Empeleni, kungaba nzima ukuthola udokotela wamazinyo ozohlinzeka ngegolide njengendlela yokukhetha. Ngaphezu kwalokho, kuthatha ukuvakashelwa okungaphezulu koyedwa ukuvakasha kahle igolide. Kodwa-ke, igolide iqinile, ayigodli, futhi ukugcwala kwegolide kungadlulela iminyaka engaphezu kwengu-15.
