Haasi ese anotengeswa zirconia powders akafanana.Misiyano pakati pezvigadzirwa muhukuru hwezviyo uye zvinowedzera zvinodzora zvakanyanya zirconia block material simba, kugadzikana kwenguva refu, uye translucency.
1. Uyezve, maitiro akasiyana-siyana ayo mazino zirconia powder anoumbwa kuita milling zirconia blocks zvinonyanya kukanganisa kunaka kwechigadzirwa chekupedzisira.Unidirectional axial pressing inogadzira milling zirconia block shape iyo yakanyatsojeka asi isina kusimba kwezvinhu uye saka haina kunaka kune yakakura kudzoreredza.
2. Kune rumwe rutivi, inotonhora isostatic pressing (CIP) inoshandisa mvura yepakati, semvura, kuisa kudzvinyirira zvakafanana kumativi ose kune zirconia powder yakavharwa muforoma kuchengetedza chimiro chayo.
3. Izvo zvakanyanya kudzvinyirirwa zvinobatanidzwa neCIP kuderedza uye kubvisa voids muupfu kuti kuwedzere kusimba kwezvinhu uye kuburitsa green-state (isinaintered) zirconia block ine yakanakisa homogeneity mukati mechinhu chose.Iyo yakasvibira-state zirconia block inozofanosiiwa kuti ibvumidzwe kugayiwa nyore uye mushure-yakagadziriswa nenyanzvi.Danho rekupedzisira rekugadzira rinosanganisira kupinza zirconia pane tembiricha yakanyanya (1350 ° C kusvika 1500 ° C) apo kudzoreredza kwekupedzisira kunoomesa uye kuderera mutsara ne20% kusvika 25% kuwana simba rinodiwa uye zvinhu zvemaziso.
Zvizvarwa zvekutanga zvesimba repamusoro CIP zirconia zvigayo zvakakonzera monochromatic uye densely opaque kudzoreredza kwairatidza kushoma esthetics kunze kwekunge akaturikidzana.Nekudaro, mukati memakore mashanu apfuura, kutsva kudzokororwa kwezvirconia block zvinhu kwakashanduka kuita milling zirconia blocks ari kufamba akananga kunogara kwakakwirira translucency uye pre-shaded zirconia block kana multilayer zirconia blocks ayo anowedzera zvakanyanya mhedzisiro uku achidzikisa maitiro ekugadzira.Kubatsira kukuru kune izvi zvakakwirira-translucency zvinhu ndezvekuti zvinoda kuderedzwa zvishoma pane monolithic girazi-ceramic kudzoreredza uye vane mutsa kune zvakasikwa zvinopikisa dentition.
Mugore rapfuura, mitsva yekugadzira zirconia milling blocks yakabatanidza izvo zvinogona kunyungudutswa mumaawa mashoma se2.Sevatatu vepamusoro zirconia block mugadziri muchina, Yucera's zirconia block inosvika zvizere ichi chinodiwa nepamusoro pekugadzira maitiro, anogona kukurumidza sintered mumaawa maviri kune imwe nyaya yekukurumidzira, pazasi 3 mauniti zirconia korona.Preshaded zirconia block uye multilayer zirconia block zvino chengetedza nguva yenyanzvi yemazino kumavara anofa, akanakira kudzoreredza-hombe.
Ndekupi kutenga mazino zirconia block?Chokwadi Yucera, gamuchirai taura nesu.
