CAD CAM Dental zirconia blocks rau crows restoration

Nyob rau hauv tam sim no, crowns tau ua los ntawm cam khwb cia hlau alloys uas muaj zog txaus kom sawv mus rau lub zog ntawm zom. Qhov zoo tshaj plaws yog qhov tseem ceeb, cov kws kho hniav siv cov plooj (porcelain) kom haum rau qhov ntxoov ntxoo ntawm cov hniav, tab sis cov khoom no muaj zog dua li kub thiab tuaj yeem ua rau qee lub sijhawm. Hniav zirconia discs yog ib qho ntawm cov khoom siv tshiab zoo li ceramic uas ua ke lub zog ntawm cov hlau nrog kev zoo nkauj ntawm cov plooj (porcelain). Ib cov ntaub ntawv los ntawm kev siv Canadian Lub Chaw Haujlwm Saib Xyuas Tshuaj thiab Tshuab hauv Kev Noj Qab Haus Huv me me luam tawm cov kws tshaj lij thiab qhov tsis zoo ntawm kev sib xyaw thiab sib xyaw ua ke ntawm cov yas tsim. Thaum cov porcelain-fused crowns tau siv rau ntau xyoo lawm, ntau dua cov khoom siv xws li zirconia yog cov txheej txheem uas twb muaj lawm uas tsis muaj kev txhim kho los kho lawv cov kev kawm txuj ci.

Qhov zoo ntawm cov hniav zirconia dawb paug

1.Nws yog qhov muaj zog heev, yuav tsum muaj kev cob qhia enamel tsawg dua li lwm cov ntaub ntawv.

2.Nws tuaj yeem muab txheej nrog cov plooj (porcelain), ntxiv rau txhim kho nws qhov zoo nkauj.

3.Zirconia crowns tuaj yeem khi los yog cemented, muab koj tus kws kho hniav xaiv ntau dua.

4.Zirconia muaj cov haujlwm ua "milled" lossis tsim hauv chaw kho hniav. Hauv lwm lo lus, koj lub kaus mom yuav ua tau thiab xa hauv ib lub sijhawm, tej zaum yuav txuag koj lub sijhawm thiab kev siv nyiaj! Cov khoom no yog biocompatible, uas muaj peev xwm tam sim no tsis yog vim li cas tsis zoo tshwm sim thaum cog rau hauv tib neeg lub cev.

Peb xaiv tawm cov hmoov zirconia zoo kawg thiab siv lub tshuab txias isostatic nias rau cov duab.Isostatic nias yog cov txheej txheem ntawm kev loj hlob ceramic hniav zirconia blocks los ntawm cov hmoov qhuav thiab siv cov kev ntxhov siab los ntawm tag nrho cov txheej txheem. Cov txheej txheem muaj los ntawm kev kaw cov hmoov zoo tag nrho rau hauv ib qho deformable mildew thiab collapsing mildew siv cov kua nruab nrab kom ua raws li kev ntxhov siab hydrostatic.
