Qhov Zoo Qhov Tsis Zoo ntawm Zirconia cov yas

Zirconia (zirconium dioxide) crowns yog ua los ntawm cov khoom monolithic zircithic zircithic zirconia tej yam khoom muaj kab ke. Txawm hais tias nrhiav tau nyob rau hauv 1789 los ntawm German Chemanist Martin Heinrich Klaprroth, zirconia tau siv los ua kev siv txij li xyoo 1960s. Nws siv ua cov khoom kho hniav rov qab ua kom nrov thaum ntxov 2000s nrog kev tawm tsam ntawm cad {}} cam thev naus laus zis. Nyob rau tom tom tom qab ib feem ntawm lub xyoo caum lawv tau muaj muaj raws li preformed crowns rau thawj hniav.

Qhov Zoo

Siab lub zog thiab kev ruaj khov
Lawv muaj lub zog siab zoo, feem ntau ntawm 900 thiab 1500 MPA, nyob ntawm cov txheej txheem tshwj xeeb thiab txheej txheem tsim khoom. Lawv muaj zog tawg thiab tuaj yeem tiv taus cov rog zoo kawg li tsim tawm thaum zom thiab tom. Hauv kev tshawb fawb soj ntsuam piv cov kev ua tau zoo ntawm cov ntaub ntawv sib txawv hauv cov khoom siv sim ua kom muaj zog ntau dua lossis qee cov tshuaj tua kab ceramic. Hauv kev siv cov kev siv, qhov no txhais tau tias zirconia cov khaub ncaws tsis tshua muaj qhov nti, tawg lossis tawg, muab cov neeg mob ntev ntev} ntev.
Zoo nkauj zoo nkauj
Niaj hnub nimno crowns muab ib qho txiaj ntsig zoo nkauj zoo nkauj. Advanced Coloring Technology tso cai rau lawv yuav tsum tau phim rau tus neeg mob cov hniav ntuj. Cov tuam txhab uas tsim tau muaj peev xwm tsim ntau qhov ntxoov ntxoo ntawm cov duab ntxoov ntxoo uas sib txawv ntawm cov duab ntxoov ntxoo sib xyaw ua ke nrog cov ntawv kho hniav ib puag ncig. Ib qho ntxiv, Zirconia muaj qee qhov kev txhais lus, zoo ib yam li cov txha hniav laus. Tsis zoo li qee cov hlau - cov ceramic crowns, uas qee zaum ua rau cov pos hniav thiab tsis muaj zog rau cov pos hniav, zirconia cov teeb meem tsis muaj qhov teeb meem no thiab muaj kev pom ntau dua.
Biocompatibility
Zirconium oxide yog biocompe heev nrog tib neeg cov ntaub so ntswg. Nws yog tshuaj lom neeg nyob rau hauv qhov chaw ntawm qhov ncauj, tsis tso tawm cov tshuaj phem, thiab tsis ua kev ua xua fab hauv cov neeg mob feem ntau. Ntau cov kev tshawb nrhiav cov kev tshawb nrhiav tau pom tias kev siv zirconia cov yas tuaj yeem txo cov tshuaj mob lossis khaus ntawm cov pos hniav ib puag ncig. Piv txwv li, ntev - lub sijhawm ua raws li cov pos hniav yog txo qis nrog cov kab mob Cov biocompatibility no ua kom tus neeg mob noj qab haus huv no thiab kev nplij siab, uas yog qhov tseem ceeb hauv kev kho hniav ua tiav.
Zoo Thermal Rwb Thaiv Tsev Khoom
Piv rau cov hlau, zirconia muaj qhov tsis zoo thermal conductivity. Cov cuab yeej no muaj txiaj ntsig zoo nyob rau hauv kev kho hniav vim tias nws pab cais cov hniav los ntawm qhov kub hloov. Thaum cov neeg mob tau haus cov zaub mov kub lossis dej txias, zirconia crowns tuaj yeem ua rau muaj kev cuam tshuam ntawm qhov kub thiab txias ntawm cov cai tswj thiab pulp. Qhov no yuav pab tswj kom muaj cov hniav kev loj hlob thiab tiv thaiv cov teeb meem hniav rhiab uas tuaj yeem tshwm sim los ntawm cov ntaub ntawv nrog cov khoom siv thermal ntau dua.
Saj zawg zog tsim cov txheej txheem
Zirconium Oxide cov yas tuaj yeem tsim nrog qhov siab precision siv lub computer {{}}}}}}}} {} {}}}}} {}}}}}}}}} {}}}} {}}} {}}}}} {}}}}}}}}} {}} {}}}}}}}} {}}}} {}}} { Cov khoom siv yog sib xws nrog ntau yam milling tshuab thiab cov ntaub ntawv software hauv kev kho hniav. Qhov no tso cai rau kev kho hniav Technicians los tsim cov kws kho hniav tsim kho kom zoo nkauj, kev cai-} ua rau cov crowns nrog ib qho tshwj xeeb haum. Lub peev xwm los ua kom pom lub zirconia block rau cov yas geometry tso cai rau tus neeg mob kho hniav txoj kev xav tau, txo qhov kev kho kom haum, thiab ua kom cov snug tau. Zirconia kuj tseem siv tau los ua ib leeg crowns, multure- Cov choj {{{kev txhawb nqa rov qab.
Xim Ruaj Khwv
Thaum tsim, zirconia crowns khaws lawv cov xim dhau sijhawm. Lawv tiv taus staining thiab tshem tawm los ntawm cov zaub mov, dej haus, thiab qhov chaw ntawm qhov ncauj. Cov xim ruaj khov no kom cov yas ua kom zoo sib xws thoob plaws nws lub neej, muab cov neeg mob uas muaj kev ntseeg siab tau yooj yim.

Tsis zoo

Tus nqi
Ib qho ntawm cov tseem ceeb ntawm cov zirconia crown yog lawv tus nqi siab, uas yog qhov siab piv rau lwm hom crowns, xws li tsoos victainin crowns lossis acrylic cords. Cov txheej txheem ntau lawm ntawm zirconia crown yuav tsum muaj siab- kev lag luam raw, thiab feem ntau cad / cam ua, uas ua rau lawv tus nqi siab. Ib qho ntxiv, cov cuab yeej siv uas yuav tsum tau ua kom zirconia, xws li cov tshuab ua tshwj xeeb xws li cov tshuab thiab cov rooj sov, tseem kim. Qhov no ua rau zirconia cov crushs nyuaj kom tau rau qee cov neeg mob lossis chaw kho hniav nrog rau cov peev nyiaj tsawg.
Kev kho kom nyuaj
Zirconium ox yog ib qho nyuaj thiab cov khoom siv loj. Thaum nws tau ua thiab muab tso rau hauv tus neeg mob lub qhov ncauj, nws yuav nyuaj rau kev hloov kho. Tsis zoo li qee cov ntaub ntawv softer uas tuaj yeem hloov kho hniav lossis kho hniav yooj yim, zirconia yuav tsum tau ua cov kev hloov kho uas tsim nyog. Piv txwv li, yog tias muaj teeb meem tom tshwm sim tom qab cov yas kho tau, nws yuav tsum muaj sijhawm ntxiv thiab kev txawj ntse los kho nws ntau dua nrog cov khoom siv suab nrov tshaj. This can increase the complexity and cost of post-installation adjustments in the dental clinic.
Tsis muaj kev so
Yog tias lub zirconia crown ua puas tsuaj, xws li tawg lossis chipped, nws feem ntau tsis yooj yim kho. Tsis zoo li qee cov hlau lossis cov ntawv sau sib xyaw, uas tuaj yeem kho tau yooj yim los ntawm kev ntxiv lossis rov kho dua qhov feem ntau, zirconia crowns feem ntau yuav tsum tau hloov. Vim tias cov khoom ntawm cov khoom siv thiab cov txheej txheem tsim khoom, nws yog qhov nyuaj rau kev rov ua kom ncaj ncees thiab kev ua kom zoo nkauj ntawm tus yam ntxwv zoo. Qhov no txhais tau tias yog tias muaj teeb meem tshwm sim, tus neeg mob yuav tau muaj lub tsheb rov qab los, uas yog qhov tsis yooj yim thiab kim dua.
Esthetics hauv cov xwm txheej tshwj xeeb
Thaum lub zirconia crown feem ntau muab kev ua kom zoo nkauj zoo nkauj, lawv yuav tsis zoo li ntuj ua lwm yam ntaub ntawv nyob rau hauv qee yam teeb pom kev zoo lossis tshwj xeeb. Piv txwv li, hauv lub teeb ci ntsa iab lossis ncaj qha, lub teeb ci ntsa iab thiab cov qauv hloov me ntsis ntawm cov hniav zirconia tej zaum, txawm hais tias qhov sib txawv no feem ntau yog hloov maj mam. Ib qho ntxiv, rau cov neeg mob uas muaj kev zoo nkauj tsis tshua muaj txiaj ntsig thiab kev ua kom hniav zoo nkauj tshwj xeeb nrog cov xim puag ncig tej zaum yuav nyuaj, cov xim zirconia cov xim nplua nuj thiab transluco cov nplua nuj xim thiab transluconency.
Qho hnyav
Zirconium ox yog ib qho khoom siv ntom ntom piv rau qee cov ntaub ntawv kho hniav. Thaum lub zog sib txawv yuav tsis pom tsis pom feem ntau, rau cov neeg mob uas muaj qhov hnyav dua, qhov kev xav zoo me ntsis ntawm cov hniav kev ntxub ntxaug lossis kev cog hniav rau lub sijhawm. Txawm li cas los xij, qhov no yog qhov kev txhawj xeeb me me uas feem ntau yog outweighed los ntawm lwm qhov zoo ntawm cov kab mob zirconia hauv feem ntau cov kev kuaj mob.
