Kev Tshawb Fawb Txog Qhov Ua Rau Muaj Teeb Meem

Kev hloov xim yog los ntawm ntau yam ua haujlwm ua ke. Kev nkag siab txog yam twg ua rau koj qhov teeb meem tshwj xeeb yuav tsum tau saib rau qhov tseem ceeb:

1. Cov kua pleev xim

Yog tias koj cov mis tshuaj pleev xim tsis tau calibrated kom raug, cov xim tawm yuav tsis phim qhov xav tau. Qhov sib xyaw ntawm txhua cov xim hauv cov kua ncaj qha txiav txim siab qhov xim kawg. Ib pawg ntawm cov kua pleev xim uas muaj cov xim daj ntau dhau, piv txwv li, yuav ua rau tag nrho koj cov kaus mom daj, tsis hais lub sijhawm ntub lossis kub. Qhov no yog qhov teeb meem sib xws uas cuam tshuam rau txhua lub kaus mom uas ua tiav nrog pawg ntawd.

2. Cov Hmoov Sib Xyaws

Cov hmoov Zirconia ntsws thaum lub sijhawm sintering - feem ntau ntawm 15-20%. Txawm li cas los xij, qhov nrawm no thiab qhov ceev kawg tsis zoo ib yam thoob plaws cov hmoov sib txawv lossis cov chaw tsim khoom. Batch A yuav muaj qhov nrawm ntawm 18%, thaum Batch B yog 19.5%. Qhov sib txawv no txhais tau tias cov khoom siv ua kom ntom dua ntawm cov nqi sib txawv thaum lub sijhawm hlawv. Cov khoom siv ntom dua nqus cov kua xim sib txawv - qee zaum tsawg dua (ua rau xim sib dua), qee zaum ntau dua (xim tsaus dua). Yog tias koj hloov cov neeg muag khoom hmoov lossis cov khoom siv thaum nruab nrab ntawm kev tsim khoom yam tsis paub tias cov khoom siv tau hloov pauv, koj yuav pom cov xim tsis sib xws thoob plaws koj lub chaw kuaj mob.

3. Lub Sijhawm Ua Kom Ntswg

Qhov no yog qhov sib txawv tshaj plaws hauv kev siv tes pleev xim. Qhov ntev koj tso zirconia rau hauv cov kua pleev xim, qhov tob dua qhov xim nkag mus thiab qhov ntau dua qhov kawg tshwm sim. Kev tso zirconia 10 feeb tsim cov xim sib dua li kev tso 15 feeb, txawm tias muaj cov kua thiab kub zoo ib yam. Qhov no ua rau pom tseeb tshwj xeeb hauv cov yas hniav nrog cov qauv occlusal - cov cusps loj thiab cov qhov tob occlusal ntub dej txawv ntawm cov chaw tiaj tus. Lub yas hniav nrog qhov chaw hniav ploj lawm (qhov khoob loj dua) yuav nqus cov kua ntau dua li cov yas hniav khov kho, ua rau muaj xim tsaus dua, ntau dua hauv thaj chaw ntawd yog tias tsis tau them nyiaj thaum lub sijhawm pleev xim.
