CAD CAM Dental Zirconia Block

 

1. Lub zog zoo & Durability: Ua kom ntev -Lub Sij Hawm Kho Mob

Qhov kom zoo dua no yog thawj qhov laj thawj vim li cas zirconia tau dhau los ua cov khoom tseem ceeb hauv kev kho hniav.

Txoj Cai Ua Haujlwm:

Siv 3Y / 4Y / 5Y stabilized zirconia formulations thiab nano- qib hmoov sintering thev naus laus zis, tsim tetragonal zirconia siv lead ua tuab. Thaum raug rau sab nraud quab yuam, tetragonal zirconia undergoes ib martensitic transformation, absorbing cuam tshuam lub zog thiab tiv thaiv tawg propagation.
Tsis tas li ntawd, nws qhov siab - ntom microstructure (kwv yees . 6.05 g / cm³)) txo qis hauv porosity, ntxiv kev txhim kho load-cov kabmob muaj peev xwm.

Cov txiaj ntsig:

① Lub zog siv tshuab siab: Peb- taw tes flexural zog ncav cuag 600–1350 MPa- siab dua li cov hniav hniav ceramics xws li iav ceramics (200–400 MPa). Nws yooj yim tiv taus cov zom zom ib txwm (200-300 MPa), tiv thaiv chipping thiab tawg.
② Lub Neej Ua Haujlwm Ntev: Zirconia qhia tau hais tias muaj tshuaj lom neeg zoo nyob rau hauv qhov chaw ntub dej ntawm qhov ncauj, tsis muaj xeb lossis kev laus. Kev kho dua tshiab tuaj yeem siv sijhawm ntev dua 10 xyoo, tshaj li 3-5 xyoo kev ua neej ntawm cov khoom siv cob-raws li cov ntaub ntawv.
③ Kev siv dav hauv kev kho mob: Lub zog siab ua rau nws tsim nyog rau cov kab hauv qab thiab cov txuas hniav uas tiv taus cov khoom hnyav, thaum tseem ua tau raws li qhov yuav tsum tau ua kom zoo nkauj rau sab nrauv kho dua tshiab.

2. Precision rau CAD/CAM ua: Xyuas kom tseeb Fabrication raug

Kev kho hniav digital xav kom cov khoom raug hloov pauv mus rau kev kho kom haum.

Txoj Cai Ua Haujlwm:

Zirconia blocks yog tsim los ntawm cov txheej txheem ua ntej -sintering (debinding), uas ua rau cov hardness nruab nrab (HRC35–40). Qhov no tso cai rau cov khoom siv los tiv thaiv CAD / CAM milling yam tsis muaj deformation lossis ntau dhau brittleness.
Its internal density is highly uniform (density variation<=0.02 g/cm³), free from impurities and pores, ensuring stable tool contact and predictable milling accuracy.

Cov txiaj ntsig:

① High Milling Precision: Tau tshaj micro-precision tsib-axis milling tshuab. Kev kho tiav tiav tswj qhov qhov tseeb ntawm qhov tsawg dua los yog sib npaug ntawm 0.05 hli, tso cai rau qhov zoo tshaj plaws marginal haum nrog qhov sib txawv me me.
② Kev ua haujlwm siab: txo qis kev ua haujlwm nyob rau hauv lub pre-sintered lub xeev shortens milling lub sij hawm mus txog 40% piv nrog tag nrho sintered zirconia. Thaum ua ke nrog ceev ceev sintering furnaces, "zoo tib yam-hnub milling thiab xa" ua tiav.
③ Kev Siv Cov Khoom Siv Siab: Cov khoom siv sib xws yuav txo cov khib nyiab thaum lub sij hawm milling. Kev siv cov nqi ntau dua 85%, txo cov nqi khoom siv rau cov chaw kuaj hniav thiab cov chaw kho mob.

3. Zoo Transparency: Sib npaug Aesthetics thiab muaj nuj nqi

Translucency yog qhov txiaj ntsig tseem ceeb uas ua rau zirconia haum rau kev kho kom zoo nkauj sab hauv.

Txoj Cai Ua Haujlwm:

Los ntawm kev tswj cov zirconia hmoov particle loj (20-50 nm) thiab sintering tsis, cov khoom siv sab hauv siv lead ua yog qhov zoo kom txo tau lub teeb tawg thiab kev xav.
Qhov sib ntxiv ntawm cov lej ntawm cov stabilizers xws li yttria ntxiv kho qhov refractive index, tuav translucency nyob rau hauv qhov zoo tshaj plaws 41% -55% ntau yam - siab txaus rau tej yam ntuj tso esthetics tab sis tsawg txaus los tiv thaiv ntau tshaj qhia- los ntawm cov hauv paus hniav xim.

Cov txiaj ntsig:

① Natural Appearance: Translucency zoo sib xws ntawm natural enamel (45%–55%), muab kev kho kom rov zoo li lub neej-zoo li luster thiab zam qhov "hlau grey" cov nyhuv pom hauv cov plooj (porcelain) -fused- rau-hlau crowns.
② Shade Versatility: Base ntxoov (A1, A2, B1, thiab lwm yam) tuaj yeem xaiv raws li tus neeg mob xav tau. Ua ke nrog translucency, qhov no ua kom cov xim zoo sib xws thiab kev sib haum xeeb zoo nkauj.
③ Zoo tagnrho rau Kev Txhim Kho Sab Nraud: Tsim nyog rau cov veneers thiab tag nrho cov -ceramic crowns, ua rau cov tsev kho mob muaj kev pabcuam siab -kawg kho hniav.

4. Antibacterial Properties: Txhawb nqa qhov ncauj noj qab haus huv

Qhov zoo dua no qhia txog zirconia qhov kev ua tau zoo hauv qhov ncauj biocompatibility.

Txoj Cai Ua Haujlwm:

Zirconia nto nthuav tawm me me alkalinity, cuam tshuam qhov pH tshuav ntawm cov kab mob ntawm tes thiab inhibiting kev loj hlob ntawm cov kab mob hauv qhov ncauj (xws li Streptococcus mutans thiab Porphyromonas gingivalis).
Tsis tas li ntawd, nws qhov ntom ntom (porosity<0.5%) provides fewer attachment points for bacteria. Zirconia is also non-toxic and does not trigger inflammatory reactions in oral tissues.

Cov txiaj ntsig:

① Txo cov kab mob adhesion: Cov kab mob tsub zuj zuj ntawm qhov chaw kho kom zoo tuaj yeem raug txo los ntawm ntau dua 60%, txo cov quav hniav thiab txo qis kev pheej hmoo ntawm caries thiab periodontitis.
② Cov txiaj ntsig kev noj qab haus huv ntawm qhov ncauj zoo dua: txo qis cov teeb meem xws li marginal gingivitis, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov neeg mob tsis zoo ntawm qhov ncauj.
③ Biocompatibility zoo heev: Ua tau raws li ISO 10993 biocompatibility qauv uas tsis muaj kev pheej hmoo ntawm kev ua xua lossis cytotoxicity, ua rau nws tsim nyog rau cov neeg mob feem ntau thiab nthuav cov chaw kho mob muaj peev xwm kho.
