I. Kev qhia lus
Kev nce qib hauv cov ntaub ntawv kho hniav tau rov kho dua cov kws kho hniav kho kom rov kho dua thiab txhim kho kev luag nyav. Ntawm cov kev hloov tshiab no, zirconia blocks tau dhau los ua kev xaiv ib qho kev ntseeg siab rau cov kaus mom, txuas hniav, thiab kho kom tsis pom kev. Lawv cov kev sib xyaw ua ke, kev thov kom zoo nkauj, thiab biocompatibility ua rau lawv mus- rau cov khoom siv rau kev kho hniav thoob ntiaj teb.
Hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm cov kab ke zirconia ntawm lawv cov ntawv thov tseem ceeb, thiab cov lus qhia tseem ceeb rau kev xaiv High- Cov kev xaiv zoo.
Ii. Dab tsi yog zirconia blocks?
- Kuv tseem hu ua kws kho hniav zirconia discs {2} {2} {2}-}} Tom qab ua kom zoo milling nrog cad / cam tshuab thiab siab- kub sintering, lawv tau hloov mus rau hauv cov hniav kho hniav.
Hniav Zirconia muaj nyob hauv ntau daim ntawv:
Dawb Zirconia blocks: Qhov zoo tagnrho rau kev cai kev cai thiab xim xim.
Ua ntej -} duab zirconia ntxoov: Tuaj nyob rau hauv vita 16 ntxoov ntxoo, txuag lub sijhawm thaum lub sijhawm tsim.
Multiilayer Zircon Blocks: Cov kev hloov zuj zus gregient translucency thiab xim rau ntuj heev -}}} saib txoj kev rov kho dua.
Ua tsaug rau cov versatility no, zirconia cov blocks yog qhov haum rau ob sab pem hauv ntej (toterior) thiab rov qab (posterior) cov pa taws.
III. Cov ntsiab lus tseem ceeb ntawm zirconia blocks
1. Koj lub zog zoo dua thiab lub zog
Zirconia muaj lub zog flexural muaj kwv yees li 1100-1200 MPa, nyob deb surpassing iav ceramics. Qhov no ua rau nws haum rau cov ntoo khaubligior crowns thiab ntev- span choj, uas yuav tsum tau nyiaj dhau kev zom zom. Zirconia txoj kev rov qab tiv thaiv kev chipping lossis tawg, muab kev txhim khu kev qha ntev- sij hawm ua haujlwm.
2. Cov tsos pom zoo
Niaj hnub nimno cov zirconia cov khoom lag luam, tshwj xeeb tshaj yog cov ntau yam tsis muaj 43-49%, ze rau cov txha hniav laus hniav. Thaum zoo stained thiab glazed, cov kev ua haujlwm no sib xyaw nrog cov hniav nyob ib puag ncig, ua rau lawv zoo tagnrho rau ob qho tib si anterior thiab posterior.
3. Biocompatibility
Ua cov hlau - dawb thiab tsis {{{1} {{1} econdhlenic, Zirconia yog maj mam rau ntawm cov pos hniav thiab biocompice siab heev. Cov neeg mob uas muaj hlau rhiab tau txais txiaj ntsig zoo los ntawm cov rov qab kho zirconia uas txo txoj kev pheej hmoo ntawm kev voos lossis kev tawm tsam.
4. Ntev -} kav xim ruaj khov
Zirconia khaws nws qhov ntxoov ntxoo dhau sijhawm, tsis zoo li qee cov chaw so lossis hlau {{}. Cov neeg mob tuaj yeem txaus siab rau lub sijhawm ntev- kav zoo nkauj tsis muaj kev txhawj xeeb txog kev tsis sib haum xeeb.
5. Ntau yam ntxiv
Los ntawm ib lub kaus mom thiab veneers mus rau ntau -}}}}}}}}} unit} unit unit impl unit unit is is,,,, in of most most most most most most materialsileile in materials်းက. Is is materials in်း. Nws qhov sib npaug ntawm lub zog, tsos, thiab kev nyab xeeb yog tso cai rau cov kws kho hniav tau siv nws hauv kev kho mob ntau.
IV. Cov ntawv thov hauv kev kho hniav
ZirconWigh blocks feem ntau yog ib feem nrog cad / cam tshuab, ua rau lawv zoo tagnrho rau:
Ib lub hau thiab tag nrho -} kev ua haujlwm sourorations
Peb {-}} -} spail choj
Cog abutments
Inlays, Onlays, thiab Veneers
Txheem Disc ntau thiab tsawg {}} mm, 95 mm, thiab 92} Yog suav nrog Roland, thiab lwm yam qhib-system li.
V. Yuav ua li cas xaiv high - zoo zirconia blocks
Tsis yog txhua zirconia cov khoom thaiv ua ke ua ke. Xav txog cov hauv qab no:
Ntawv pov thawj:ISO 13485 {-} Tau lees paub thiab FDA-sau npe cov blocks kom zoo ib txwm ua kom zoo thiab kev nyab xeeb.
Hmoov So Los:High -}} Grad Filders los ntawm Nyiv (TOSOH) lossis Tuam Tshoj (Sinocera) muab lub zog zoo thiab qhov muag pom.
Cov kev xaiv ntxoov ntxoo:Qhov muaj ntawm cov vita 16 ntxoov ntxoo lossis cov multalayer blocks pab ua tiav cov hniav hniav hniav.
Kev sib haum xeeb:Paub meej tias cov blocks haum koj lub cad / cam tshuab (qhib system (95 hli, 98 hli, lossis 92 × 75 mm).
VI. Cov Lus Nug
Q1: yog zirconia crowns muaj zog dua cov pob cell (cov pob zeb)?
Yog lawm. Zirconia cov yas muaj ntau ruaj khov, tiv taus chipping, thiab muaj kev piv rau cov yeeb yaj kiab rau porcelain {}} hlau (pfm)
Q2: Pab tau zirconia yuav siv rau cov hniav pem hauv ntej?
Kiag li. Multiilayer Zirconia muaj cov lus txhais lus siab, ua rau nws tsim nyog rau kev ua kom xav tau kev kho mob anterior.
Q3: Ntev npaum li cas ua zirconia rov qab so?
Nrog rau kev tu kom zoo, zirconia crowns thiab choj tuaj yeem nyob rau 10-15 xyoo lossis ntev dua.
Q4: Dab tsi yog qhov sib txawv ntawm pre -}}}}} shaired thiab multiilayer zirconia blocks?
Pre {-}} Cov xim xim tuaj hauv ib qho xim tsis zoo, thaum cov khoom siv multilayer muab cov xim me thiab transitions kom tau txais txiaj ntsig zoo.
VII. Tag
Cov pob zeb zircon tau dhau los ua lub pob zeb uas niaj hnub kho tsev, muab lub zog tsis muaj zog, kev ua kom zoo nkauj, thiab kev nyab xeeb. Los ntawm ib lub kaus mom ua ke los ua cov choj thiab cog hniav tsis zoo, zirconia muab cov txiaj ntsig tau zoo, ntev}}} kav cov txiaj ntsig.
Thaum xaiv Zirconia, Tshaj Tawm ISO 13485 -}} Cov ntaub ntawv muaj ntawv tso cai thiab FDA-sau npe los xyuas kom zoo thiab tus neeg mob kev nyab xeeb. Xaiv txoj cai Zirconia tso cai kho hniav los muab cov kws kho mob los muab kev txhim kho uas yog ob leeg ua haujlwm txaus siab.
