Kev taw qhia txog cov tshiab tag nrho -ceramic crowns tau ua kom muaj koob meej ntawm kev kho dua tshiab. Lawv tam sim no muaj zog dua, txhim khu kev qha thiab zoo nkauj dua li yav dhau los. Zirconia blocks kuj nrov heev, nrog rau cov kev xaiv suav nrog cov khoom monolithic zirconia thiab cov zirconia zoo heev, ob qho tib si uas muaj kev zoo nkauj zoo nkauj. Cia peb saib seb lwm hom muaj dab tsi.
Monolithic Zirconia
Khoom lossis monolithic tag nrho contoured zirconia crowns yog qhov zoo tagnrho rau kev kho tom qab thiab muaj zog heev. CAD fabricated crowns muab ib tug meej marginal haum thiab yog zoo unbreakable.
Thaum ntxov monolithic zirconia crowns feem ntau dhau- muaj nuj nqis, tab sis maj mam, cov ntxoov ntxoo tau zoo tuaj thiab tam sim no tuaj yeem ua tau zoo sib xws rau cov hniav uas nyob ib sab. Cov nyhuv ntxoov ntxoo pab ua rau lub ntsej muag occlusal ntawm lub crown, thiab preshaded zirconia crowns muab lub ntuj opalescence. Qhov smoothness thiab durability ntawm qhov chaw ua rau monolithic zirconia crowns xaiv haum rau cov molar.
Dawb Garnet Compressible Crowns
Keeb kwm qhia ntau tshaj 15 xyoo dhau los, cov dawb garnet compressible yas muaj 160 MPa flexural lub zog thiab tau ua pov thawj kom ruaj thiab zoo nkauj. Siv cov txheej txheem no, cov kws kho mob tuaj yeem ua tiav cov kev kho kom zoo dua qub uas zoo sib xws. Daim ntawv qhia kev ntxoov ntxoo pwm yog siv los txiav txim qhov ntxoov ntxoo ntawm kev npaj cov hniav thiab pab txiav txim siab qhov ntxoov ntxoo ntawm cov hniav.
Dawb Garnet Crowns yog cov translucent heev thiab pab hloov cov xim ntawm cov hniav uas nyob ib sab, yog li cov xim sib xws tuaj yeem ua tiav txawm tias nyuaj dua.
Lithium disilicate porcelain crowns
Lithium disilicate crowns yog tsim los ntawm biocompatible lithium disilicate ceramic iav ingots thiab muaj lub zog flexural ntawm 400 MPa, Crowns tuaj yeem nias los yog hauv av kom haum thiab ua haujlwm zoo. Tag nrho -cov ntaub ntawv rov qab tuaj yeem tsim tau siv lithium disilicate, txheej txheej txheej ceramic uas ua tiav qib siab ntawm kev zoo nkauj.
YILINK lithium disilicate yog tsim los ntawm cov txheej txheem tshwj xeeb uas cov khoom tseem ceeb yog lithium disilicate. Nws cov txheej txheem crystallization ceev ceev thiab zoo nkauj zoo nkauj tau ua rau nws cov khoom xaiv rau kev ua tau zoo, siab -lub zog CAD kho dua tshiab.
Highly translucent zirconia
Pob tshab zirconia yog tshwj xeeb tshaj yog haum rau anterior crowns, tab sis kuj yuav siv tau rau tom qab crowns. Nws muaj cov nyhuv translucent zoo li qub nrog lub zog khoov ntawm 590 thiab 720 MPA. Cov khoom siv yog biocompatible heev, txhawb kev noj qab haus huv cov ntaub so ntswg thiab muaj ib tug zoo nkauj tsos.
Ib zaug nyob rau hauv lub qhov ncauj, High Translucency Zirconia kis cov xim ntawm cov hniav uas nyob ib sab yog li cov kev kho kom zoo nkauj yuav muab zoo kawg nkaus. Highly translucent zirconia yuav siv tau raws li ib tug monolithic restoration los yog nyob rau hauv cov khaubncaws sab nraud povtseg.
Nrog rau niaj hnub no kev xaiv ntawm tag nrho cov -ceramic cov ntaub ntawv, nws yuav tsum yooj yim heev rau cov kws kho mob los xaiv qhov yog hom crown.YILINK cov kev paub txog pab neeg yog npaj los qhia rau koj raws li peb nyob rau hauv - kev paub tob ntawm cov ntaub ntawv no.Own Hoobkas, thawj-chav kawm zoo, txais tos los tham
