Nyob rau hauv cov xwm txheej dab tsi yog qhov pom zoo los tsim cov khoom siv kws kho? Lub crown yog cov hniav cuav ntawm cov hniav tsim nyog hauv kev puas tsuaj ntawm cov neeg muaj kev puas tsuaj, tsis muaj ntau yam kev ua txhaum, thiab, tau ua txhaum ntawm cov duab ntuj thiab xim.
Soviet txiv neej yuav txawv nyob rau hauv "hlau hniav". Tom qab ntawd, cov kws kho mob - kws kho hniav tuaj yeem xav txog kev nyab xeeb ntawm cov hniav, dua li ntawm kev ua kom muaj nuj nqis, thiab tsawg kawg ntawm cov nyhuv zoo nkauj ntawm cov khoom siv dag ntxias. Hmoov tsis zoo, cov thev naus laus zis tseem siv.
Nws yuav tsum tau sau tseg tias kev kho hniav yog kev loj hlob tsim hauv kev tsim kho xyoo tsis ntev los no.
Cov lus hlau ua los hloov cov hlau hlau. Cov kab hlau no kab nrog Ceramics, uas tso cai rau koj hloov cov xim thiab cov qauv ntawm cov kaus hniav ib txwm ua tau.
Ib qho qauv tsim nyog uas cov kws kho mob yuav nruab tsis tsuas yog nyob rau hauv thaj teb ntawm cov hniav pem hauv ntej, tab sis kuj tseem rov qab muaj kev ncaj ncees ntawm kev zom zom. Lawv tau zoo los ntawm cov qub hlau stamped crowns, tshwj xeeb tshaj yog cov ntom ntawm haum rau cov nqaij mos ntawm cov hniav. Tab sis muaj tau meej meej cons. Cov kev zoo nkauj yuav tsum tau them ib qho txaus ntim ntawm cov ntaub so ntswg. uas yuav tsum txiav, thiab feem ntau thiab "tshem tawm cov hlab ntaws" los ntawm cov hniav noj qab nyob zoo. Hlau hlau nplaum sib ceg tseem cuam tshuam. Dhau ntawm xyoo dhau los, cov thev naus laus zis tshiab tau tshwm sim uas tso cai ua qhov tseeb tshaj plaws, thiab ntau lub dag zog yog qhia ua haujlwm nrog cov ceramic loj. Ntawm cov hlau ceramic yas, nrog txhua qhov naturalness, nws tau tig mus ua ib qho rho tawm ntawm lub teeb ci, xav txog nws, thiab qhov no cuam tshuam txog qhov naturalness ntawm xim. Kev ua xua rau cov hlau alloys muaj peev xwm ua tau. Muaj qee kis, tus qauv tsim los ua ntau lub sijhawm kim dua, vim muaj cov khoom siv hlau ntau, uas muaj cov khoom siv hlau uas muaj txiaj ntsig, thiab lwm yam tab sis lawv yog biologically inert.
Kuv rov hais dua, cov qauv tsim no muaj feem xyuam rau hnub no. Kev ua haujlwm nquag tab tom tsim kom muaj cov ntaub ntawv zoo nkauj rau cov khoom siv ntawm cov yas thiab tshawb rau cov thev naus laus zis tshiab.
Cov hlau thav duab tau hloov los ntawm cov khoom siv muaj zog heev - zirconium dioxide, uas muaj biologity inertness thiab muaj ob peb ntxoov ntxoo ntawm cov hniav nyob ze xim. Nws tsis tas yuav cov stratification ntawm ntau cov hniav txhuam hniav. Yas los ntawm Zirconia yog tsim raws li cov thev naus laus zis tshiab tshiab. Yuav kom ua tiav qhov siab tshaj plaws ua kom zoo nkauj, ceramics tau thov rau Zircon.
Crowns los ntawm tag nrho cov organic ceramics muaj qhov zoo tshaj plaws kev ua kom zoo tshaj plaws. Ntau yam xim ntawm cov xim, txha hniav laus qauv yog tsim los ntawm txheej kev sib kis ceramic. Hauv qhov ncauj kab noj hniav, xws li cov ris tsho tsis sib txawv ntawm txhua yam ntawm cov hniav hniav sib txawv, vim tias lawv tsis muaj ncej. Tab sis nws yog qhov zoo uas ua rau nws cov kev txwv. Xws li cov kaus mom yog qhov tsis yooj yim heev. Yog li ntawd, lawv tsuas tuaj yeem ntsia tau ntawm cov hniav pem hauv ntej,
uas tau ntsib ib qho kev thauj khoom me dua li cov chewable. Tseem muaj ntau dua cov crowns los ntawm cov khoom siv hluavtaws. Piv txwv li, e-. Milling txoj kev los ntawm cov blocks ruaj ua rau lawv siv lawv thiab sab hniav. Lub tshuab milling me me tshwm sim hauv txee ntawm kws kho hniav thiab cia koj ua cov yas ua kom muaj tus neeg mob ib zaug.
Tshaj tawm, Kuv xav hais qhov tseem ceeb tshaj plaws: Tsuas yog koj tus kws kho hniav tuaj yeem xaiv cov yas khoom tsim tawm, tom qab koj muaj kev paub meej.
