Lithium Disilicate, Zirconia, Resin Matrix-Sib piv
Oct 14, 2022
Muaj ntau ntau cov ntaub ntawv nyob rau hauv kev ua lag luam thaum nws los txog rau kev kho hniav. Niaj hnub no peb yuav los sib piv lithium disilicate, zirconia, thiab cob. Lawv pros, cons, thiab indications yog dab tsi?
Pros:
Lithium Disilicate muaj lub koob npe nrov rau kev zoo nkauj. Nws zoo ib yam li cov hniav ntuj uas tsis muaj kab grey nyob ib ncig ntawm cov npoo. Nws kuj muaj peev xwm ua kom sib raug zoo thiab tswj cov ntxoov ntxoo thiab translucency. Nws kuj muaj ib tug loj pro, nws yooj yim heev rau zeb, uas tuaj yeem xa tuaj rau tib hnub. Raws li rau zirconia, zoo biocompatibility, superior zog, durability, thiab zoo esthetics yog nws cov yam ntxwv. Ua rau nws yog ib qho khoom siv nrov thaum nws los txog rau kev kho hniav. Txawm hais tias lithium disilicate thiab zirconia muaj tag nrho cov khoom siv zoo tshaj plaws thiab zoo nkauj, resin muaj cov txiaj ntsig tseem ceeb ntsig txog nws cov machinability thiab intra-oral reparability.
Cons:
Lithium disilicate lub zog yog qis dua zirconia. Yog li nws yog qhov zoo tagnrho rau veneer, inlay & onlay, thiab crown. Zirconia yog qhov zoo rau cov molars vim nws lub zog siab, uas mus txog 1300MPa. Ntawm qhov tod tes, lub zog siab yuav ua rau muaj kev sib txhuam tawm tsam cov hniav. Rau cov resin, lub hardness thiab lub zog yog tsawg tshaj li lithium disilicate thiab zirconia. Thiab cov xim tsis ruaj khov li zirconia thiab iav ceramic.
Cov lus qhia:
Lithium disilicate qhia rau veneer, onlay & inlay, crowns, thiab peb-unit choj. Zirconia yog siv rau txhua rooj plaub. Resin tuaj yeem siv rau veneer, onlay & inlay thiab.
Ua tsaug rau cov thev naus laus zis, CAD CAM cov ntaub ntawv thiab cov software muaj kev cuam tshuam tas li, cov kws kho hniav yuav tuaj yeem muab cov neeg mob kom muaj tseeb dua, muaj zog ruaj khov kho.
