Izinzuzo eziningana ze-zirconia all-ceramic porcelain denture

1. Ubuhle

Ukubuyiselwa kwamazinyo e-ceramic wonke kunokubukeka okungokoqobo nokuhle, futhi umbala ufana namazinyo emvelo. Okubaluleke kakhulu ukuthi zonke-ceramic amazinyo okufakelwa abe translucency omuhle futhi refraction, futhi ngeke kube khona imigqa emnyama entanyeni yezinyo, ukuze intamo yezinyo ikwazi futhi ukufeza umphumela omuhle wobuhle, okungenakwenzeka ukubamba okujwayelekile amazinyo okufakelwa e-porcelain.

2. I-Biocompatibility

I-Zirconia yezicelo zezokwelapha nezamazinyo inezakhiwo ezinhle kakhulu ku imigomo ye-biosafety. Ngokuhamba kweminyaka, inani elikhulu lokuhlola kanye nemitholampilo amacala afakazele ukuthi i-zirconia ayinawo umonakalo onobuthi emathanjeni nasezicutshini ezithambile amaseli, futhi ayikho imibiko yokungezwani komzimba.

3. Amandla aphezulu kanye nokuminyana

(1) I-Zirconia ceramics iyi-yttrium-stabilized zirconia ceramics enokuphakama amandla e-flexural. Njengamanje, amandla wezinto ezibhaliswe eChina anazo ifinyelele ku-900MPa, kuyilapho izinga likazwelonke lezinto zamazinyo lingu-100MPa.

(2) Uma kuqhathaniswa nezinye izinto zokubuyisela i-ceramic, amandla we izinto ze-zirconia zenza odokotela bathole amandla aphezulu kakhulu ngaphandle ukugaya ngokweqile kwamazinyo angempela esiguli. Phakathi kwabo, Vita all-ceramic I-plus-yttrium kanye ne-plus-stabilized oxide Zirconia yaziwa nangokuthi i-ceramic insimbi.

4. Ukuqonda

Ukukhiqizwa kwenziwa ngokuklama okusizwa ngekhompiyutha, ukuskena nge-laser, kanye ukugaya ngekhompyutha. Iqinisekisa ukunemba kokubhekana okubunjiwe kanye nokuqina okuhle komphetho, okwenza izinyo le-porcelain lilingane kahle ne- i-abutment emlonyeni wesiguli.

5. I-radioactivity ephansi

Amazinga we-State Food and Drug Administration anezindinganiso eziqinile kuzo zonke izinto zobumba ezimakethe, futhi zingasetshenziswa njengezokwelapha kuphela izinto ezisetshenziswayo ngemva kokuhlangabezana nezidingo zokuhlolwa kwe-radiological. Hhayi kuphela zikhona yini izidingo ze-zirconia, kodwa futhi ne-porcelain yokuhlobisa, i-alumina, ingilazi zobumba, njll Ukuhlola kubonisa ukuthi radioactivity of zirconia okumsulwa i-powder ayigcini nje ngokuphansi kune-ceramics yengilazi, kodwa futhi iphansi kunalokho wezicubu zethambo lomuntu.
