Multilayer Zirconia

Kev tsim cov kev nce qib hauv zirconia tau coj mus rau niaj hnub no' cov khoom tshiab. Multilayer zirconia discs yog qhov tshwj xeeb hauv qhov tseeb tias lawv tau ua ntej-shaded thiab muab cov xim gradient los ua kom zoo nkauj zoo nkauj.

Cov neeg tsim khoom tam sim no muaj peev xwm tsim cov zirconia discs nrog lub ntuj tsim-hauv kev hloov pauv ntawm dentin mus rau incisal. Qhov no ntuj gradient nyob rau hauv lub disc tsim cov txiaj ntsig zoo ib yam li cov txheej txheem tsim cov khoom siv tes ua yooj yim. Nrog multilayer zirconia ua cov khoom siv kho dua tshiab, cov chaw soj nstuam tuaj yeem siv CAD / CAM thev naus laus zis rau nws lub peev xwm tag nrho.

Tom qab txheej txheem tiav tam sim no tau dhau los ua qhov kev kwv yees tau zoo thiab tuaj yeem rov ua dua thaum siv kom raug hauv chav kuaj niaj hnub no. Kev kho dua tshiab yog tsim los ntawm tag nrho cov contour, tom qab ntawd milled, thiab theem ntsuab yog tiav los ntawm kev siv qhov chaw zoo nkauj thiab cov yam ntxwv. Txawm hais tias tsis tas yuav tsum tau ua raws li cov neeg tsim khoom pom zoo feem ntau, qhov no yog qhov uas tus kws tshaj lij' kev ua yeeb yam pab coj lub peev xwm tiag tiag ntawm cov khoom siv rau lub neej.

Kev lees txais thoob ntiaj teb ntawm zirconia hauv kev kho hniav yog qhov hloov pauv. Qhov no yog ib feem vim qhov txwv kev npaj cov hniav, cia cov kws kho hniav siv cov txheej txheem npaj lawv tau ua rau ntau xyoo.

Tom qab sintering, qhov kho dua tshiab yog thaum kawg kho thiab kuaj xyuas qhov tseeb ntawm qhov tuag. Thaum qhov kev kho dua tshiab tau lees paub tias yog qhov tseeb, cov txheej txheem stain-thiab-glaze yooj yim ua tiav tus kheej tus yam ntxwv ntawm qhov kawg kev kho dua tshiab.

Kev siv cov zirconia multilayer tso cai rau kev kwv yees cov haujlwm ua haujlwm digital los ntawm kev kuaj mob mus txog qhov kawg kev kho dua tshiab. Cov txiaj ntsig zoo nkauj no yav dhau los tsuas yog ua tau nrog cov txheej txheem kev ua haujlwm hnyav tab sis tam sim no ua tiav hauv ib chav tsev rau kev kho lub qhov ncauj tag nrho yam tsis xav tau daim ntawv thov ceramic.

Multilayer zirconia yog tam sim no muab los ntawm ntau lub tuam txhab, thiab cov kev hloov tshiab txuas ntxiv mus rau kev lag luam. Vsmile muaj peb hom (STML , UTML, SHTML) ntawm multilayer zirconia disc nrog sib txawv translucency thiab lub zog kom tau raws li koj tus kheej xav tau.

Muaj ib tsev neeg tshiab ntawm zirconia uas suav tias yog gradient zirconia. Cov ntsiab lus yttria nyob rau hauv zirconia matrix muaj ntau theem ntawm cov concentrations nyob rau hauv tib lub disc, muab lub sij hawm rau cov kws kho mob muab lub sij hawm rau muab lub restoration nyob rau hauv qhov zoo tshaj plaws qhov chaw nyob rau hauv nesting rau lifelike esthetics. Muab CAD tsim rau anterior monolithic crowns nyob rau sab saum toj ntawm lub disc yuav ua rau ntau translucent restoration nrog qis MPa qhov tseem ceeb thaum muab lub restoration ntawm sab qis ntawm lub puck yuav muab qis concentrations ntawm yttria, thiab yog li ntawd ua ib tug muaj zog (siab dua. MPA), ntau opaque zirconia, tsim nyog rau substructures thiab thav duab. Cov gradient zirconia ntau yam tsis muaj qhov sib txawv ntawm cov khaubncaws sab nraud povtseg, tab sis theej muaj gradient lossis ntau yam ntawm Y5 nyob rau sab saum toj, hloov mus rau Y4 hauv nruab nrab thiab thaum kawg Y3 hauv qab. Nrog multilayer zirconia ua cov khoom siv kho dua tshiab, cov chaw soj nstuam tuaj yeem siv CAD / CAM thev naus laus zis rau nws lub peev xwm tag nrho.
