Cov Lus Nug Txog Dental Zirconia

Sintered dental zirconia muaj qhov dawb thiab txhais tau tias ntau heev zoo li tus hniav. Yog li ntawd, nws yog ib qho yooj yim kom ua tau zoo nkauj zoo nkauj nyob rau hauv tag nrho contour zirconia restorations. Monolithic restoration ntawm zirconia yog qhov feem ntau tau rov ua kom tau. Raws li tsis muaj cov tshuaj cog ntawm zirconia thiab tej hub, muaj cov plooj (porcelain) ntawm tej qhov chaw hauv lub plhaub ntub yuav ua rau delaminate thaum lub sijhawm. Qhov no yog qhov tseeb tshwj xeeb tshaj rau cov pos hniav thiab cov khoom cog hniav raws li kev kho kom zoo. Sintered zirconia yog ib qho yooj yim heev thiab cov kua qaub neeg pov thawj uas tiv thaiv qhov nqus thiab qhov dej ntawm cov pa paug (xws li cov quav hniav). Monolithic zirconia restorations muab ib tug neeg mob "huv si" zoo nkauj thiab ua rau kom zoo

Sintered zirconia yog ib qho yooj yim heev thiab cov kua qaub neeg pov thawj uas tiv thaiv qhov nqus thiab qhov dej ntawm cov pa paug (xws li cov quav hniav). Monolithic zirconia restorations muab ib tus neeg mob "huv si" zoo nkauj thiab ua rau kom muaj kev noj qab haus huv cov ntaub so ntswg. Qhov kev pom zoo tseem ceeb rau kev kho vaj tse rov qab los ntawm qhov kev xaav tias lawv yog cov khoom ntiag tug heev rau cov kev sib txawv ntawm cov hniav. Peb yuav tsum tsis txhob cuam tshuam lub zog ntawm zirconia nrog abrasiveness. Qhov saum npoo ntawm zirconia yog heev ntom, tus, ruaj khov thiab tsis-txhoj puab heev. Nyob rau hauv cov kev tshawb fawb ua tiav nyob rau hauv xyoo tas los nws yog proven tias monolithic zirconia yog qhov tsawg tshaj plaws abrasive ntawm tag nrho cov khoom restorative thiab txawm tsawg abrasive ces ntuj cov hniav.

Ntawm no yog qee cov lus nug thiab cov lus teb hais txog kev kho hniav zirconia, nws siv thiab kev ntseeg tau tias yog cov khoom siv kho hniav kom zoo:

1. Ua zirconia crowns yuav tsum npaj tshwj xeeb?

Tsis tau. Hnub no txoj kev tsim ntawm zirconia crowns pub rau kev lees txais txhua hom kev npaj thiab lav lav tshwj xeeb (marginal thiab lwm yam). Nrog monolithic zirconia, prep yuav txhag heev. Nrog me ntsis li 1 hli clearance zoo nkauj thiab cov khoom muaj zog heev yuav tsim tau.

2. Kuv puas yuav tsum tau siv cov dej tsuag dej tsuag rau zij zirconia?

Muaj. Zirconia yog ib tug neeg ua haujlwm kub heev. Kev sib tsoo tsis muaj dej-tsuag yuav tsim tau qhov kub kub ntawm qhov chaw ntawm cov yas (dhau 1,000 acres). Nyob rau hauv cov kub cov qauv ntawm zirconia nyob rau hauv qhov chaw no yuav hloov, uas yuav ua rau tsim ntawm micro tawg thiab weakening ntawm restoration.

3. Kuv puas yuav tsum tau siv cov cuab yeej tshwj xeeb los ua haujlwm ntawm zirconia crown?

Peb pom zoo siv nplua diamonds rau zirconia. Cov hmoov nplej yuav tshem / txiav zirconia zoo heev thiab yuav kav ntev dua. Medium los yog ntxhib burs tau clogged ceev nrog zirconia plua plav thiab yuav tsis tshem tawm cov khoom, tab sis tsis tseem ceeb overheat qhov nto.

4. Puas yuav ua kom zirconia restorations ntawm txhua hom / hom ntawm cov implants?

Muaj. Hauv peb lub tsev kho mob hniav, peb tsis muaj kev txwv nyob hauv hom tshuaj lossis hom tshuaj. Ua raws li rooj plaub, ncaj qha cov khaws cia los yog cemented crown rau kev cai los yog prefabricated abutment muaj peev xwm yuav ras txog ntawm tej qhov system cog.

5. Puas muaj kev txwv rau qhov loj ntawm kev ncua kev zirconia restoration lossis cov pontics hauv choj zirconia?

Yog tsis muaj kev txwv rau kev ncua ntawm tus choj zirconia los yog mus rau qhov nyiaj ntawm pontics. Tsuas yog tus qauv tsim. Qhov loj dua qhov kev ncua deb ntawm cov kab txaij siab ntev thiab dav dua cov neeg sib txuas yuav tsum. Txawm li cas los xij, nyob rau hauv lub teeb ntawm kev ruaj ntseg ntawm cov ntaub ntawv no, lub tswv yim ntawm kev kho hniav yuav tsum tau ua kom tiav. Hauv peb lub studio, peb niaj zaus tsim ib qho chaw kom zoo dua qub thiab tuaj yeem hais qhia tau zoo txij thaum xyoo 2007. Peb tau tsim cov kev cai yoojyim rau kev ua haujlwm kom ntev ntev thiab muaj peev xwm lav tau cov ntaub ntawv uas tau ua nyob rau hauv peb lub studio.

6. Hom kev sib tsoo yuav tsum siv rau zirconia restoration?

Hauv paus ntsiab lus, zirconia restorations tuaj yeem kho tsau nyob rau hauv qhov chaw siv cov hniav sib tsoo. Txawm li cas los xij, nws yuav tsum tau sau tseg tias zirconia tsis ua rau, yog li ntawd rau inlays thiab onlays, raws li tau zoo raws li cov kev txuas mus rau hauv maryland, yuav tsum tau kho dua qub ntxiv rau kev npaj thiab kev kho kom rov qab.
