Zirconia Vs Lithium Disilicate: Lub neej yav tom ntej ntawm All-Ceramic Dentistry
May 25, 2023
Zirconia tau dav siv rau ntau yam kev kho txhua yam-ceramic. Txawm li cas los xij, lithium disilicate muaj qhov zoo nkauj zoo nkauj, sawv cev rau yav tom ntej txoj kev loj hlob ntawm tag nrho cov ntaub ntawv ceramic.
1. Lithium disilicate tuaj yeem ua tiav qhov tuab yam tsawg kawg nkaus ntawm 0.2 hli uas zoo dua li cov hniav zoo nkauj. Zirconia yuav tsum muaj qhov tsawg kawg nkaus thickness ntawm 0.5mm rau lub zog txaus, uas ntau cuam tshuam cov hniav npaj thiab esthetics.
2. Lithium disilicate restorations tuaj yeem muaj 30-50 feem pua tsawg dua ntim ntawm cov hniav qub piv rau zirconia. Qhov no txhais tau tias tsawg dua tshem tawm cov hniav zoo nkauj thiab zoo ib puag ncig.
3. Ntau yam ntawm lithium disilicate cov ntaub ntawv thiab cov ntawv thov tau nce zuj zus, muab kev xaiv ntau dua thiab kho kom haum rau cov kws kho hniav thiab cov neeg mob.
4. CAD/CAM thev naus laus zis ua kom yooj yim rau kev ua haujlwm ntawm lithium disilicate kho dua tshiab, ua kom ceev lawv cov kev coj ua hauv kev kho mob.
5. Lithium disilicate exhibits superior translucency rau pom esthetic tshwm sim. Nws cov fluorescence ntuj kuj txhim kho qhov tseem ceeb ntawm kev kho dua tshiab.
Thaum zirconia tseem yog cov khoom siv txhim khu kev qha, muaj zog thiab ntau yam khoom siv rau tag nrho cov khoom siv ceramic, lithium disilicate tau dhau los ua kev sib tw thiab kev sib koom ua lag luam sai sai, tshwj xeeb tshaj yog nyob rau thaj tsam yav tom ntej, vim nws qhov sib piv tsis zoo thiab yooj yim. Kev tsim kho thev naus laus zis yuav nthuav dav ntxiv rau qhov qhia txog lithium disilicate kom suav nrog cov yas tom qab, inlays, onlays thiab veneers.
Lub neej yav tom ntej ntawm kev kho hniav tag nrho-ceramic yog tag nrho ntawm cov lus cog tseg thiab xav tsis thoob. Nrog rau ntau yam khoom siv thiab cov thev naus laus zis thev naus laus zis, tag nrho cov txheej txheem ceramic tuaj yeem ua rau cov hniav zoo nkauj ntawm ob lub zog thiab kev zoo nkauj. Cov kws kho hniav tam sim no muaj cov cuab yeej tshaj lij los muab cov neeg mob sai dua, kev kwv yees thiab kev daws teeb meem ntev ntev rau lawv txoj kev luag nyav. Lithium disilicate thiab zirconia yog coj txoj hauv kev mus rau qib tom ntej ntawm kev vam meej.
