CHOOSING LET ZIRCONIA

Ntau tus neeg mob ntawm koj tus kws kho hniav yuav tsis paub txog qhov zoo ntawm cov ntaub ntawv tshiab -Lithium Disilicate los yog Zirconia-rau kev kho hniav kom zoo dua cov khoom PFM, tiam sis CAD / CAM thiab Ceramic technologies yog hloov cov PFMs sai heev.

Muaj ntau yam zoo rau kev siv LD lossis Zirconia dhau PFM, tiam sis kuj muaj ntau yam tseem ceeb uas yuav cuam tshuam koj xaiv ib yam khoom rau lwm tus rau koj cov neeg mob kho hniav. Txhua cov ntaub ntawv muaj nws tus kheej zoo thiab kev pom zoo siv. Piv txwv li:

Zog: Zirconia muaj lub zog ua haujlwm siab tshaj plaws, mus txog 1400 mPa, thiab yog tus cwj pwm tawm tsam kev tawm tsam dua Hom III Kub Alum. Cov kev tshawb fawb qhia tias hnav kom tawm tsam kev sib tw tsis yog tshwm sim los ntawm cov ntaub ntawv nyuaj tab sis los ntawm qhov dej txhav los yog "cov nyom sandpaper". Thaum peb ua Zirconia, saum npoo yog heev polished thiab glazed, ua nws heev tus. Zirconia tseem hnav ntau dua li kub, yog li ntawd nws tuav nws cov qauv qub, thiab yuav tsis cuam tshuam rau qhov kev tawm tsam ntawm kev coj deformation los ntawm mastication ntawm cov zaub mov los yog ntev txhawm. E.max Lithium Cov khoom siv qis, nrog cov khoom siv qis tshaj li ntawm 500 mPa, yog tsim los rau cov khoom siv sab nrauv ntau tshaj plaws thiab kev zoo nkauj.

Esthetics / Accuracy in Shade Matching: High-translucency e.max Lithium Disilicate tau pom zoo tias qhov twg yog qhov tseem ceeb - piv txwv, nyob rau hauv cov xwm txheej uas koj xav tau raws nraim qhov ntxoov ntxoo ntawm ib cov hniav qub. Rau txhua tus neeg luag nyav, los yog lwm yam xwm txheej uas tib neeg cov hniav tsis xav tau qhov sib txawv txav, feem ntau Cov Kws Khomob tau tshaj tawm Zotic Zirconia cov ntaub ntawv.

Cov kev nce qib hauv Zirconia pub rau ntau ntxoov ntxoo txuam thiab tsis muaj cov pob dawb zoo li cov laus zirconia khoom.

Thinness : Vim hais tias Zirconia cov ntaub ntawv muaj zog heev, lawv tuaj yeem ua cov ntsiab lus uas koj xav tias koj tuaj yeem muaj kev txuag ntxiv hauv koj qhov kev npaj, txuag ntau tus neeg mob 'thawj tus qauv hniav. Zirconia tej zaum yuav yog li nyias ½ hli; qhov tsawg tshaj plaws thinness ntawm e.max Lithium Disilicate cov ntaub ntawv yog 1.5 hli mus rau 2 mm.

Kev Txhim Kho Txheej Txheem : e.max Lithium Disilicate khoom yuav tsum tau raug etched thiab bonded rau qhov chaw, thaum Zirconia yuav conventionally cemented, ua cov txheej txheem yooj yim.
