Qhov zoo ntawm Zirconia Ceramic Ceramic Block hauv Cov Kho Hniav
Zirconaunle Ceramic Ceramic Blocks yog qhov siv tau dav hauv kev kho hniav vim lawv lub zog ua kom zoo, zoo dua li kev tsim kho lub teeb ci, thiab cov txiaj ntsig zoo nkauj.
Lub zog siab thiab Hardness:
Ua kom muaj Zarcalics ua rau muaj lub zog siab zoo, pob txha tawv tawv, thiab vickers tawv tawv, ua rau lawv muaj ib qho khoom muaj zog tshaj plaws ceramic. Nrog lub mohs tawv ntawm kwv yees li ntawm 8.5, zirconia ceramics yog cov kev khawb thiab hnav, sib piv rau cov hlau, ua kom lawv zoo tshaj rau cov ntawv thov uas yuav tsum tau coj tsis kam.
Zoo heev biocompatibility:
Cov ceraconia ceramics tsis txhob ua rau cov pos hniav thiab tsis muaj peev xwm ua rau cov kab mob hauv qhov ncauj. Lawv cov thermal tsawg conductivity pab tiv thaiv txoj kev kho hniav thiab tiv thaiv kev txhais ntawm cov pulpitis. Ib qho ntxiv, zirconia ceramics yog biocompible, lub ntsiab lus lawv tsis ua kev tsis haum tshuaj, kev ua xua, ua rau lub neej ntev piv rau cov ntaub ntawv ib txwm muaj piv rau cov ntaub ntawv ib txwm muaj.
Qib siab thermal rwb thaiv tsev:
Vim yog lawv cov kev ua haujlwm tsawg dua, cov ceraconia muab cov pa hluav taws xob zoo heev, ua kom haum rau kev siv hluav taws xob, ua rau lawv haum rau cov ntawv thov rwb thaiv tsev.
Lub Hnav Tsho:
Txawm hais tias lawv muaj lub zog zoo nkauj thiab tawv tawv, ua kom zoo nkauj heev, muab kev ua tau zoo tshaj plaws ntawm kev ua tau zoo thiab yooj yim ntawm kev tuav.
Zoo zoo nkauj ua kom zoo nkauj:
Zaws cov kab ceramics ua kom ze rau cov xim ntawm cov hniav ntuj, rov qab kho qhov zoo li qub thiab ntxo ua haujlwm ntawm cov hniav. Lawv muab lub ntuj zoo nkauj, zoo li yog cov hniav loj hlob ntawm cov pos hniav.
Cov kev zoo no ua cov kab ke zoo zirconia cov khoom siv zoo tshaj plaws hauv kev kho hniav thiab kho hniav thiab kev kho mob kom zoo nkauj.
Cov ntawv thov ntawm Zirconia Ceramics hauv kev kho hniav
Yog siv rau cov ntaub ntawv qhia txog peb lub cncyclystal: Tetragoncystal, magnesia-ruaj khov alumina (zta). Cov ceramics no muaj cov khoom tsim nyog rau kev kho hniav tsim nyog, ua kom zoo nkauj uas tsis muaj kev ua xua, tsis muaj kev fab tshuaj tsis zoo, tsis muaj kev ua xua nruab nrab.
Cov kws kho hniav txiav nyiaj:
Zirconia ceramic abutments yog nyiam rau lawv tus nqi zoo nkauj hauv kev kho tus hniav anterorical. Lawv tau hloov cov nyom txij li xyoo 1990, tshem tawm cov tshuaj tiv thaiv kab mob hauv lub qhov ncauj thiab cov nqaij ib puag ncig, suav nrog kev kub ntxhov, thiab xim hlau.
Crowns:
Zirconia cov yas tau raug xaiv hla hlau thiab kub crowns rau lawv lub zog, durability, thiab kev zoo nkauj. Lawv tuaj yeem ua tiav tag nrho, translucent, los yog fished zirconia. Qhov yoog tau ntawm Zirconia Ceramics tso cai rau lawv yuav tau sib khi lossis ntsia rau hauv qhov chaw. Cov khoom siv lub zog ua rau lawv haum rau cov hniav khaus lossis cov neeg mob uas muaj zom.
Cog abretments:
Zirconia cov kev cog lus kev cog lus ntsig txog kev ua kom muaj ntau yam, tso cai tsim kev siv CAD lossis cov qauv wax rau kev cai fittings. Lawv tiv thaiv lub teeb rau hauv cov pos hniav nyias, tswj kev ua kom zoo nkauj thiab txuam nrog cov hniav uas nyob ib sab.
Orthodontic nkhaus:
Multiilayer Zirconia Crecaconia Crecackts tau hloov Alumina Cleamic nkhaus thiab hlau nkhaus hauv cov orthodontics. Lawv ua haujlwm los ntawm kev txwv rau cov hniav, ua kom txoj kev zawm hniav 'cov xov dej kom deb ntawm cov hniav.
Kev cog hniav:
Kev cog lus ntawm kev kho hniav kab ntsig txog kev kho hniav, pom zoo siv xyoo 2011, muab biocompatibility thiab kev ruaj khov zoo. Tsis zoo li cov hlau screws, zirconia kev cog hniav tsis ua kom haum rau kab mob thiab cov kab dub ntawm cov yoov, muab ntau txoj kev teeb tsa. Hlau-Dawb Zirconia kev cog hniav zoo dua rau cov pos hniav ntawm cov pos hniav thiab tartar tsawg dua thiab Tartar, tshwj xeeb hauv ib-thooj kev cog lus. Zaulions zirchoonia 'siab flexural zog thiab fracture todness kom nruj thiab ntev-ntev fittings.
Tsim ntawm Zirconia Ceramic Block

Cov txheej txheem tsim khoom thiab cov qauv xim
Cov txheej txheem tsim kho hniav rau kev kho hniav Zirconia ceramic ceramic muaj xws li kev ua cov txheej txheem thiab kev kho xim.
Txoj kev tsim cov txheej txheem:
Ob txoj hauv kev yog siv:
Khaub thuas isostatic nias (CIP):Qhov no cuam tshuam nrog nias qhuav, iasteratic nias, ua ntej-sintering, thiab machining. CIP yog yooj yim thiab txuag tab sis me ntsis tsawg translucent thiab qis dua hauv lub zog thiab tawv. Kev kho kom haum hauv hmoov cov ntsiab lus, cov hom tsis sib xws thiab cov txheej txheem Sintering tuaj yeem txhim kho kev hloov pauv, ceev, lub zog, thiab tawv.
Qos Casting:Qhov no cuam tshuam nrog kev npaj slurry slurry, molding, kom qhuav, demolding, thiab machining. Qos pov tseg ua zirconia cov blocks nrog cov translucency zoo, ceev, thiab tawv tab sis nyuaj dua thiab yuav tsum tau tswj hwm nruj.
Cov hau kev Coloring:
Ob txoj hauv kev tau siv los ua zirconia ceramics 'xim ze rau cov hniav ntuj:
Khoom-lub xeev doping thiab conspination:Los ntawm kev sib xyaw xws li cov roj predymium, cov hlau, cerium, cerium, cerium, cerium, thiab manganese rau hauv cov hmoov, tus nqi xim tuaj yeem hloov kho kom phim lub vite16 xim nplai.
Soluble ntsev tov kev sib xyaw ua ke thiab suav:Siv cov ntsev soluble ntawm preaseymium, cerium, cerium, cerium, thiab mangoranctions, thiab cov neeg sawv cev sib txawv, npog cov xim kho hniav ntawm cov pej xeem sib txawv.
Cov txheej txheem no ua kom pom tias zircon ceramic blocks muaj tsis tsuas yog cov kev ua kom zoo nkauj thiab kuj tau thov kev pab kho hniav.
Qhov Zoo Ntawm Cov Qauv Kev Lag Luam
Khaub thuas isostatic nias (CIP):
Hom qauv no yog cov cwj pwm los ntawm kev yooj yim thiab kev ua haujlwm siab. Txawm hais tias nws txhais lus yog qis me ntsis, kev hloov kho me ntsis hauv cov txheej txheem Sintering tuaj yeem txhim kho cov khoom siv cov khoom.
Qos Casting:
Thaum yooj yim nyuaj, npleem ua kom yooj yim ua zirconia cov thaiv nrog translucency, ntom, lub zog, thiab tawv. Nws yog qhov zoo tagnrho rau cov ntawv thov uas xav tau cov qauv zoo nkauj kom zoo nkauj.
Kev kho xim
Khoom-lub xeev doping thiab conspination:
Los ntawm kev sib xyaw ua ke cov oxides zoo li praseodymium, cov hlau, cerium, cerium, lub txiaj ntsig kev ua kom tau cov xim ze rau cov hniav uas muaj cov hniav sib txawv.
Soluble ntsev tov kev sib xyaw ua ke thiab suav:
Hom no cuam tshuam nrog kev siv ntsev ua kom tsim cov xim tsis muaj xim uas npog ntau cov xim sib txawv, yog li catering rau ntau tus neeg mob cov neeg mob.
Tag
Zirconia cov kev thaiv ceramic muaj ntau yam thiab cov khoom siv tau zoo rau cov ntawv thov kev kho hniav. Lawv lub zog siab, kev txhawb nqa biocompatibility zoo nkauj, zoo dua li kev xaiv kho kom zoo nkauj, thiab kev kho zoo rau kev kho hniav thiab kho kom zoo nkauj. Cov txheej txheem tsim kev lag luam ua kom ntseeg tau tias txoj kev tsim xim uas tsis yog tsuas yog ntsib tab sis ua rau muaj kev xav tau ntawm cov kev daws teeb meem niaj hnub no, muab cov kev xav tau txaus rau cov neeg mob thoob ntiaj teb.
