Feem ntau hais lus, muaj zog, tawg toughness, lub teeb transmittance, xim kev loj hlob thiab txiav kev ua tau zoo, thiab lwm yam. Tau kawg, qhov qis dua qhov ntsuas hluav taws xob, qhov zoo dua, qhov qis dua cov tshuaj solubility, qhov zoo dua, qhov ntau dua qhov kev tiv thaiv kev laus, qhov zoo dua, thiab lwm yam. Qhov no yog cov hniav A yuav tsum- muaj rau ceg - siv zirconia
Peb feem ntau tham txog lub zog thiab pob tshab ntawm no. Functionally, nws yog lub zog; aesthetically, nws yog pob tshab thiab lub suab, uas yog, xim nyhuv (ntawm chav kawm, muaj cov ntaub ntawv, tab sis tsis qhia ntawm no). Txhawm rau ua kom muaj kev kho dua tshiab uas txaus siab rau cov neeg mob ob qho tib si ua haujlwm thiab zoo nkauj, ob qho tib si yog qhov tseem ceeb.
Tsis muaj zirconia thaiv uas tuaj yeem ua tau raws li qhov sib txawv ntawm txhua qhov kev kho hniav. Peb paub tias peb yuav tsum hnav cov khau ncaws pob ntaus pob, khau ncaws pob ncaws pob ncaws pob, khau ntaus pob ncaws pob ntaus pob, thiab lwm yam. Qhov no yog vim cov kev ua si sib txawv hauv kev ua kis las muaj qhov sib txawv ntawm kev quab yuam thiab quab yuam ntawm ko taw, thiab nws kuj suav nrog kev tiv thaiv ko taw. Kev thov. Tib yam muaj tseeb rau zirconia. Lub zog siab yog tsim rau cov molars thiab cov kav hlau ntev; siab transparency yog haum rau anterior hniav restoration nrog siab aesthetic xav tau. Tau kawg qee tus neeg hais tias yog tias lub zog thiab pob tshab ntawm zirconia siab, puas yog txhua yam siv tau? Lub tswv yim yog tag nrho, qhov tseeb yog tawv. Cov kev txwv ntawm txhua yam tuaj yeem pom nyob txhua qhov chaw hauv ntiaj teb, thiab cov chaw tsim khoom siv raw khoom tau tshawb nrhiav thiab groping ntawm cov hom phiaj, thiab lawv yuav tsum tau tos. Qhov xwm zoo yog tias zirconia raw cov ntaub ntawv nrog ob lub zog thiab kev xa tawm tau tshwm sim ib zaug. Piv txwv li, cov khoom lag luam nrog lub zog ntawm 1100MPa thiab kev xa tawm ntawm 47% tau tshwm sim hauv khw.
Txawv zirconium thaiv cov tuam txhab muaj npe sib txawv me ntsis rau lawv cov khoom. Feem ntau ntawm lawv muaj npe tom qab qib ntawm pob tshab, xws li siab-permeability zirconia, ultra-permeable zirconia, ultra-permeable zirconia, thiab lwm yam.; qee lub npe los ntawm daim ntawv thov, xws li zirconia rau cov hniav anterior, zirconia rau cog thiab lwm yam.
Cov xim ntawm zirconia tau maj mam tsim los ntawm tib lub ntuj xim (White) mus rau Vita16 xim. Qee cov tuam txhab lag luam kuj tau qhia lawv cov xim tshwj xeeb kom tau raws li cov kev xav tau ntawm cov xim sib txawv ntawm kev lag luam thiab kev sib tw. Cov tsos ntawm cov xim zirconium tuaj yeem txo lossis tsuas yog tso tseg cov kev ua haujlwm dyeing tom ntej, uas tsis tsuas yog txo cov kev ua haujlwm ntawm cov neeg ua haujlwm, tab sis kuj tseem tswj cov kev ua haujlwm ntawm zirconia nws tus kheej, thiab zam qhov tsis zoo ntawm kev ua haujlwm dyeing uas tuaj yeem ua rau txo qis zog. yam. Nyob rau hauv lub neej yav tom ntej, cov xim zirconia blocks yuav hloov tag nrho cov xim zirconia blocks.
Rov qab mus rau lub pob tshab ntawm zirconia, cov tuam txhab siv pob tshab kom paub qhov txawv tshwj xeeb, uas yog cov pob tshab siab, super pob tshab, tsis tshua muaj pob tshab, thiab lwm yam rau npe lawv cov khoom. Ua ntej ntawm tag nrho cov, peb yuav tsum paub hais tias tsis muaj tus qauv nyob rau hauv cov hniav tej hub khoom kev lag luam uas stipulates dab tsi yog siab transparency, dab tsi yog super transparency, thiab dab tsi yog ultra transparency. Cov npe no tau sau los ntawm txhua tus neeg tsim khoom. Qhov no zoo li tib neeg thoob plaws ntiaj teb, sib txuas lus nrog lawv tus kheej cov lus, qee tus tuaj yeem nkag siab ib leeg, thiab qee tus tsis paub yuav hais li cas. Yog li ntawd, nws tsis yog qhov tseeb tias qhov siab transparency ntawm A chaw tsim tshuaj paus yog qhov tsis tshua muaj pob tshab dua li ntawm B chaw tsim khoom. Tom qab ntawd peb yuav tsum sib txuas lus hauv cov lus uas txhua tus tuaj yeem nkag siab. Cov℃ntawm pob tshab yog qhia los ntawm lub teeb transmittance, thiab lub zog yog qhia los ntawm peb -point dabtsi yog khoov zog.
