Peb Vim Peb Yuav Tsum Sib Tham Zirconia

Kev kho hniav zirconia tau txais ntau qhov chaw hauv kev kho hniav, ua rau ntau cov kws kho mob tuaj yeem nug txog cov tswv yim zoo tshaj plaws rau zirconia restorations. Cov teeb meem nram qab no kuj yog ib qho tseem ceeb thaum xaiv cov sib tsoo rau zirconia restoration:

1. Koj Tsis Paub Tseeb Zirconia Hom Koj Lub Hniav Siv

I do not know

Muaj ntau hom zirconia muaj nyob rau hauv kev ua lag luam, nrog rau zirconia nrog (1) lithium disilicate zoo li translucency thiab cov flexural zog ntawm kwv yees li 550 txog 600 MPa, (2) cov lus muaj zog thiab ntau dua 1,000 MPa nrog cov lus siab zog thiab luv translucency , thiab (3) lub dag zog nruab nrab ntawm kwv yees li 750 txog 800 MPa thiab kev txhais lus siab. Cov ntaub ntawv no muaj cov khoom sib txawv sib txawv uas yuav cuam tshuam cov txheej txheem ntawm tsevneeg.

Pa roj carbon ntau yam muaj zog zirconia tau qhia ntev lub sij hawm soj ntsuam zoo cementing reini-hloov iav ionomers. Cov kev tshawb fawb tsis ntev los no tau qhia, txawm li cas los xij, cov kab caws reen yuav tsum tau siv rau cov ntaub ntawv zirconia txhais vim lawv sib zog ua qhov nqaum tsawg dua piv rau cov ntaub ntawv muaj zog. Tsis tas li ntawd, ib txoj kev tshawb kawm tsis ntev los no qhia tau hais tias cov tsho uas txhais tau hais tias ploj zom zaws (sandblasting high-translucent zirconia) tuaj yeem tsis muaj zog ntawm cov khoom siv hauv kev ua lag luam. Yog tias koj tsis paub tseeb tias hom zirconia koj lub plhaub thaum twg siv, ua raws li kev sib txuas lus nrog koj cov txheej txheem xuab zeb niaj hnub ua ke yuav pab tsim tau qhov kev paub tseeb.

2. Xyuas kom zoo tshaj

Zoo marginal haum ntawm prosthetic crowns yog ib qho tseem ceeb yuav tsum tau ua kom tiav ib tug ruaj restoration. Txawm tias tag nrho cov kev tsim kho tshiab, kev ua zoo, ntev ntev marginal seal ntawm tus hniav-crown interface tseem tuaj yeem ua ib qho kev sib tw zoo. Txoj kev haum xeeb tsis haum xeeb yuav ua rau muaj teeb meem kev kuaj mob. Cov txheej txheem siv thaum tsim crowns siv CAD / CAM tej zaum yuav cuam tshuam cov marginal qhov sib txawv piv rau cov pa nrum povtseg. Hauv ntau cov kev tshawb fawb, MDP-based adhesive restorations pom tsom qhov ntev mus rau hydroxyapatite. 10-MDP tau pom tias yuav ua kom zoo zoo zirconia.

3. Cov kev txhim kho loj hauv Cov Cim Kho Dua Tshiab tau ua kom yooj yim siv

Ntau lub tsev kho mob nyiam cov iav iav ciam iab vim lawv cov neeg siv tus cwj pwm nta, xws li tsis muaj cov kauj ruam kev kho mob thiab kev tshem tawm ntau dhau. Hauv yav dhau los, cov ciaj cij zoo li PANAVIA F 2.0 tau samfwm kom cov kws kho mob ua cov primers thiab ua rau kev tshem tawm cov nyom ntau dhau. Tam sim no, peb muaj cements zoo li PANAVIA V5, uas yog ib qho yooj yim mus siv thiab muaj peev xwm yooj yim tshem tawm cov cement ntau nrog tack-curing. Feem ntau cov kws kho mob nyiam cov nqi ntawm zirconia thiab qhov yooj yim ntawm cementation. Nrog kev sib tw tsis ntev los no hauv cov qauv ciaj, PANAVIA V5 tuaj yeem ua qhov zoo rau kev sib tw rau zirconia crowns.

Siv 10-MDP-based cob qhia cement yuav yog ib qho tseem ceeb hauv cov txheej txheem kev sib haum xeeb ntawm cov zirconia rov qab.
