Crowns feem ntau siv nrog kev cog hniav los hloov cov hniav uas ploj lawm lossis lwj. Lawv kuj tau siv los ua choj thiab thauj tog rau nkoj rau cov hniav ib nrab.
Porcelain thiab kub tau ntev yog cov khoom siv niaj hnub siv los tsim cov hniav hniav. Porcelain crowns muab lub ntsej muag zoo nkauj dua, tab sis feem ntau yuav nti. Cov kaus mom kub yog qhov kim tshaj plaws, tab sis lawv tsis pom zoo thiab tuaj yeem tsim kev tsis haum tshuaj. Cov hniav hniav tuaj yeem ua los ntawm zirconium. Zirconia crowns muab ib tug zoo heev tej yam ntuj tso tsos yam tsis muaj teeb meem tshwm sim.
Dab tsi yog zirconium?
Zirconium yog ib qho siv lead ua muaj zog uas muaj ntau yam zoo. Crystals paub txog lawv cov durability thiab indestructibility. Zirconium yog tsis muaj kev zam. Ntxiv nrog rau nws lub zog thiab ua haujlwm ntev, zirconium tau sib haum nrog tib neeg lub cev, ua rau nws nrov rau kev siv hauv kev kho mob.
Cov txiaj ntsig tseem ceeb ntawm zirconium
1 Biocompatibility
Vim hais tias lub cev tsis tsis lees paub zirconium, qhov kev pheej hmoo ntawm kev kis kab mob, muaj teeb meem, mob, tsis xis nyob thiab kev tsis haum rau lub kaus mom raug txo.
2 Nkaum kev kho hniav
Zirconium nyiam dua cov plooj (porcelain) rau kev zais thiab zais cov hniav puas tsuaj los ntawm staining lossis puas.
3 Cov qauv hniav tsawg yuav tsum tau muab tshem tawm
Feem ntau, thaum xav tau ib lub kaus mom, ib txheej ntawm cov hniav qub raug tshem tawm kom tso cai rau lub kaus mom kom haum nws zoo. Lub zog ntawm zirconium txhais tau hais tias yuav tsum muaj txheej nyias nyias rau cov yas. Ib tug thinner crown yuav ua rau tsawg dua ntawm cov hniav qub raug tshem tawm.
4 Durability
Ua los ntawm siv lead ua, zirconium yog qhov zoo tshaj plaws tsis muaj kev puas tsuaj thiab tuaj yeem tiv taus kev zom zaub mov ntau tshaj plaws thiab tom. Qhov tseeb, zirconium yog tsib npaug zog dua plooj (porcelain)! Lawv kuj tseem tiv taus qhov kub thiab txias txias, uas txo qhov zaus ntawm cov hniav khaus ntau rau lwm hom yas.
5 Sib phim cov hniav ntuj
Txawm hais tias lawv cov kev tsim kho muaj zog, zirconium crowns tau yooj yim zoo li tus, loj thiab xim kom phim tus neeg mob cov hniav ntuj. Nws ntseeg tau tias qhov ductility ntawm zirconium crowns tso cai rau kev tsim cov yas zoo nkauj dua li cov yas qub uas nws hloov. Lub peev xwm los tsim cov duab zoo meej, qhov loj me thiab xim muab cov neeg mob zoo dua, zoo dua qub.
6 Ntev - kav ntev
Ntxiv nrog rau lawv cov kav ntev, zirconium crowns kav ntev dua li cov plooj (porcelain crowns). Qhov no feem ntau yog vim zirconium tiv taus ntau dua rau chipping thiab tawg.
Nws tuaj yeem hloov kho tau yooj yim, hloov kho thiab xim.
7 Kev zoo nkauj
Zirconium crowns yog translucent thiab ua los ntawm siv lead ua. Qhov tseeb, translucent tsos ntawm zirconium tso cai rau cov hniav zoo meej shading uas zoo tshaj plaws rau tus neeg mob cov hniav xim, zoo dua rau cov kub lossis cov plooj (porcelain crowns).
8 Tsis tas yuav tsum muaj hlau
Tsis zoo li kub lossis cov plooj (porcelain crowns), zirconium crowns tsis tas yuav tsum tau fused rau lub hauv paus hlau, uas ua rau cov tsoos tsoos zoo nkauj dua. Zirconia crowns muab kev nplij siab, kev ruaj ntseg, hnov, durability thiab zoo li cov hniav ntuj.
Yog xav paub ntxiv txog zirconium crowns thiab kawm paub ntau ntxiv txog yuav ua li cas lawv tuaj yeem muab rau koj zoo nkauj, ntuj -zoo luag,tiv tauj peb ntawm Yilinkhnub no. peb cov kws tshaj lij kws tshaj lij muab rau koj nrog cov ntaub ntawv zoo tshaj plaws kom koj tuaj yeem tsim tshwj xeeb, tus kheej cov yas yas rau koj cov neeg mob.
