Tsis yog tag nrho cov khoom lag luam muaj zirconia hmoov zoo ib yam.Qhov sib txawv ntawm cov khoom nyob rau hauv grain loj thiab additives zoo heev tswj cov zirconia thaiv cov ntaub ntawv lub zog, ntev stability, thiab translucency.
1. Tsis tas li ntawd, cov txheej txheem sib txawv los ntawm kev kho hniav zirconia hmoov yog tsim rau hauv milling zirconia blocks cuam tshuam qhov zoo ntawm cov khoom kawg.Unidirectional axial nias tsim milling zirconia thaiv cov duab uas meej heev tab sis tsis muaj cov khoom sib xws thiab yog li tsis zoo rau kev kho kom zoo dua qub.
2. Ntawm qhov tod tes, txias isostatic nias (CIP) siv cov kua nruab nrab, zoo li dej, siv lub siab sib npaug ntawm txhua qhov kev taw qhia rau zirconia hmoov ntim rau hauv pwm kom tswj nws cov duab.
3. Qhov kev ntsuas siab heev koom nrog CIP txo thiab tshem cov veeps rau hauv cov hmoov av thiab tsim cov khoom siv ntom ntom nti nrog homog tsem nyob thoob plaws hauv tag nrho cov khoom siv.Lub xeev ntsuab zirconia thaiv yog tom qab ua ntej sintered kom nws yooj yim milled thiab tom qab ua tiav los ntawm tus kws tshaj lij.Cov kauj ruam kawg ntawm kev tsim khoom suav nrog sintering zirconia ntawm qhov kub siab heev (1350 ° C mus rau 1500 ° C) uas qhov kawg kev kho kom zoo dua qub thiab shrinks linearly los ntawm 20% mus rau 25% kom ua tiav qhov xav tau lub zog thiab kho qhov muag.
Thawj tiam ntawm lub zog siab CIP zirconia milling cov ntaub ntawv tau ua rau monochromatic thiab densely opaque restorations uas nthuav tawm txwv kev zoo nkauj tshwj tsis yog txheej txheej.Txawm li cas los xij, nyob rau hauv 5 xyoo dhau los, cov khoom tshiab ntawm zirconia thaiv cov ntaub ntawv tau hloov zuj zus mus rau hauv milling zirconia blocks uas yog trending mus rau puas dua translucency thiab pre-shaded zirconia blocks los yog multilayer zirconia blocks uas zoo heev ua rau esthetic tshwm sim thaum txo cov txheej txheem ntau lawm.Ib qho txiaj ntsig zoo rau cov ntaub ntawv muaj txiaj ntsig zoo no yog tias lawv yuav tsum tau txo qis dua li monolithic iav-ceramic kho dua tshiab thiab zoo dua rau kev tiv thaiv kev kho hniav.
Nyob rau hauv lub xyoo dhau los, cov qauv tshiab ntawm zirconia milling blocks tau suav nrog cov uas tuaj yeem sintered li ob peb teev.Raws li peb sab saum toj zirconia thaiv cov chaw tsim khoom hauv Suav teb, Yucera's zirconia thaiv tag nrho ncav cuag qhov yuav tsum tau ua nrog cov txheej txheem ntau lawm, uas tuaj yeem ceev sintered hauv 2 teev rau qee qhov xwm txheej ceev, hauv qab 3 units zirconia crown.Preshaded zirconia thaiv thiab multilayer zirconia thaiv zoo txuag cov kws kho hniav lub sijhawm rau cov xim tuag, zoo tagnrho rau kev kho qhov loj.
Qhov twg yuav cov hniav zirconia thaiv?Yucera kiag li, txais tos hu rau peb.
