Zirconia yas thiab kub kub yas thiab PFM hlau yas
Nov 21, 2018| 
Ob peb xyoos tom qab, thaum koj mus xyuas koj tus kws kho hniav kom tau ib lub khoom yas rau koj cov hniav, feem ntau koj yuav tsum muaj ob txoj kev xaiv. Koj yuav tau xaiv ntawm ib qho kub raws li cov yas los yog ib qho fais fab tuag rau hlau (PFM) crown. Txawm hais tias kev siv cov prottheses taag npaj los ntawm cov hlau kub los ntawm cov pob zeb tau raug txo tsawg heev li ob peb xyoos, tag nrho cov ntoo thiab cov khoom PFM tseem yog cov khoom siv feem ntau siv cov yas thiab khoom siv choj. Txawm li cas los xij, nws tsis yog li ob peb xyoos tom qab thaum zirconia raws li cov crowns thiab txuas hniav tau nkag los rau hauv kev kho hniav kev kho mob thiab tau qhuas rau lawv lub zog zoo thiab kev ntseeg. Tam sim no, feem ntau txoj kev kho hniav yog hloov los ntawm cov PFM thiab cov yas dhia ntawm cov zirconia siv rau cov ntawv kho hniav tas.
Zirconia yog dab tsi?
Zoo, qhov no yog qhov nthuav! Zirconia, los yog zirconium dioxide yog ib qho hlau oxide uas yog ib hom kab xaum qhuav; Txawm li cas los xij, nws muaj cov khoom uas muaj ntau yam txawv ntawm cov khoom siv kab mob uas tau siv yav tas los. Tsis tsuas zirconia crowns thiab txuas hniav nqa tau zoo kawg nkaus esthetics, tab sis lawv kuj zoo siv tsis zoo lawm!
Cov txiaj ntsig ntawm Zirconia tshaj lwm cov ntaub ntawv yas Cov Khoom Siv
Cia peb kawm saib yog vim li cas zirconia tab tom ua cov khoom qub thiab khoom siv ntawm cov kws kho hniav thiab cov neeg mob tib yam:
Exceptional Zog - lub zog zoo heev los ntawm zirconia crowns yog ib leeg nws tus kheej txaus rau kev tawm tsam lawv siv rau crown thiab choj fabrication. Tsis muaj teeb meem dab tsi koj ua los yog noj nrog koj zirconia crowns, lawv yuav tsis lov los yog puas!
Superb Esthetics - tsis muaj ib yam zoo li cov khoom siv los ntawm zirconia. Zirconia ua raws li cov tub ntxhais kawm zoo tshaj plaws rau kev hniav ntoo thiab cov txuas hniav, dhau uas tsim glazing thiab uas ua tau kom ua tau los tsim cov khoom tsim thiab cov khoom qub zoo nkauj.
Durability - zirconia tseem muaj zog ntau dua li siv cov PFM ceramics conventionally. Thaum koj tau txais koj cov hniav txhawb nqa nrog zirconia crowns, koj tsis tas yuav txhawj txog lawv cov kev ua ub no ntxiv lawm.
Machinable Prostheses - Cov kws kho hniav ua haujlwm niaj hnub ua zirconia crowns thiab cov choj los ntawm kev siv CAD CAD kev pabcuam milling lossis 3D printing. Cov tswv yim no tsis yog tsim cov khoom qab hau uas haum zoo, tab sis cov hluav taws xob kuj yog cov khoom zoo nkauj tshaj li txhua txheej ntawm cov yas yuav tsum yooj yim kho kom haum nrog tus neeg mob tus cwj pwm ntuj.
Kev Nyab Xeeb thiab Biocompatibility - Txawm tias zoo licas los ntawm cov khoom siv kub thiab cov txuas hniav, muaj qee tus neeg mob tseem yuav tau ntsib ib co kev fab tshuaj nrog lawv. Zoo sib xws, cov kws kho hniav feem ntau kuj yog cov ua xua rau cov phom sij uas siv rau cov khoom ntawm PFM crowns. Ntawm qhov tod tes, zirconia tau ua kom zoo tshaj plaws biocompatibility thiab cov crowns thiab txuas hniav tau npaj los ntawm zirconia tsis tshua muaj kev ruaj ntseg rau kev soj ntsuam siv hauv lub qhov ncauj kab noj hniav.
