Yuav paub dab tsi txog kev kho hniav veneers

Cov veneers hniav yog dab tsi

Cov hniav veneers yog cov khoom siv tshwj xeeb uas tsim los pab zais lossis kho cov hniav puas, suav nrog:

• Stains thiab discoloration

• Cov Qos Yaj Ywm Chips thiab Cov Khoom Me Me Uas Ploj Lawm

• lwj

• yuam kev

• qhov sib txawv ntawm cov hniav

Cov hniav veneers pab txhim kho qhov zoo nkauj ntawm ib tug neeg cov hniav. Lawv yuav pab tau rau cov neeg uas tab tom nrhiav kev daws teeb meem zoo nkauj mus sij hawm ntev, tshwj xeeb tshaj yog cov neeg uas tsis tau teb rau lwm yam kev kho hniav xws li kev ua kom hniav dawb, braces, lossis retainers.

Thaum lub sijhawm muab cov hniav tso rau hauv, feem ntau cov kws kho hniav yuav tshem tawm me ntsis cov enamel, uas yog lub plhaub tiv thaiv ntawm cov hniav. Vim li no, thaum tus kws kho hniav tau muab cov veneers tso rau hauv, ib tus neeg yuav tsis tuaj yeem tshem tawm lossis xaiv tsis siv lawv.

1. PMMA veneer

Cov khoom tseem ceeb ntawm cov veneer resin: composite resin + cov khoom porcelain zoo. Cov khoom siv lub cev (lub zog) yog li 400MPa; nws yog ua nyob rau hauv tus neeg mob lub qhov ncauj thiab ncaj qha thov rau ntawm qhov chaw hniav, thiab tom qab ntawd kho los ntawm lub teeb kom rov qab kho qhov tsis zoo thiab npog cov xim tsis zoo uas cuam tshuam rau qhov zoo nkauj ntawm cov hniav. Txoj kev no yooj yim thiab siv tau, yooj yim kho, thiab tus nqi qis, tab sis qhov zoo nkauj thiab kev ruaj khov yog qhov phem dua me ntsis, thiab nws yooj yim rau zas xim.

2. Cov veneer porcelain

Cov khoom tseem ceeb ntawm cov porcelain veneer: feldspar, kaolin, quartz, thiab lwm yam. Cov khoom siv lub cev (lub zog) yog li 90MPa. Cov txheej txheem ntau lawm feem ntau yog sintered nrog porcelain hmoov, thiab cov yam ntxwv tseem ceeb yog qhov tseeb thiab cov xim txheej, siab permeability (txwv shading nyhuv), vim tias cov hmoov ceramic sintering shrinkage ntug tsis haum.

3. Cov iav ceramic veneer

Cov khoom tseem ceeb ntawm cov iav ceramic veneer: lithium disilicate + iav matrix. Cov khoom siv lub cev (lub zog) yog li 400MPa. Cov txheej txheem ntau lawm feem ntau yog kev txiav tshuab molding, cov yam ntxwv tseem ceeb yog kev nkag tau zoo, cov duab ntug meej, kev tsim khoom yooj yim thiab ceev, cov xim thaiv cov nyhuv txwv.

4. Zirconia Veneer

Lub ntsiab tivthaiv ntawm zirconia veneer yog zirconium dioxide. Cov khoom siv lub cev (lub zog) yog ntau dua 900MPa. Cov txheej txheem ntau lawm feem ntau yog kev txiav tshuab molding, cov yam ntxwv tseem ceeb yog qhov nyuaj tshaj plaws, cov duab ntug meej, kev tsim khoom yooj yim thiab ceev, cov xim zoo thaiv, thiab kev pom tseeb siab, piv txwv li, kev pom tseeb ntawm 3D-Pro ML tuaj yeem ncav cuag 42% -49%, yuav luag sib piv rau cov resin.

Qhov txawv ntawm veneers, crowns thiab implants yog dab tsi?

Cov hniav veneers, cov crowns, thiab cov implants tuaj yeem ua rau koj cov hniav zoo nkauj dua. Txawm li cas los xij, muaj qhov sib txawv ntawm lawv.

Ib qho txawv ntawm cov veneers, crowns thiab implants yog thaj chaw ntawm cov hniav uas txhua txoj kev xaiv npog.

Cov hniav veneers feem ntau npog sab xub ntiag ntawm cov hniav. Qhov sib txawv, cov yas hniav npog tag nrho cov hniav, suav nrog sab xub ntiag, nraub qaum, thiab txhua sab. Yog li ntawd, cov kws kho hniav siv cov yas hniav los kho cov hniav tawg, suav nrog cov uas tsis muaj zog. Cov yas hniav kuj tseem tuaj yeem pab txhawb cov hniav uas lawv npog.

Lub implant, lub sijhawm ntawd, yog ib qho qauv zoo li ntsia hlau uas txuas rau lub puab tsaig los hloov cov hniav uas ploj lawm.

Thaum tsim nyog, tus kws kho hniav yuav siv cov hniav cuav los tuav lub kaus hniav kom ruaj khov hauv qhov ncauj. Qhov no tuaj yeem tshwm sim yog tias ib tus neeg poob ib tug hniav lossis yog tias ib tug hniav tawg dhau lawm uas kho tsis tau thiab yuav tsum tau rho tawm.

Feem ntau, cov kws kho hniav siv cov yas hniav los kho cov hniav uas puas lawm loj heev, thaum cov hniav cog rau hauv cov hniav hloov cov hniav uas ploj lawm. Cov hniav veneer ua rau cov hniav uas tseem zoo nkauj dua.

Yuav ua li cas saib xyuas koj cov hniav tom qab veneers?

• Tom qab kho cov hniav cuav tas, tsis txhob noj cov khoom noj uas txias dhau los yog kub dhau rau lub sijhawm luv luv.

• Siv cov txhuam hniav uas muaj cov plaub mos mos, thov tsis txhob txhuam koj cov hniav hnyav dhau.

• Tsis txhob siv cov tshuaj txhuam hniav uas muaj cov noob loj, vim tias cov hmoov me me hauv cov tshuaj txhuam hniav yuav cuam tshuam rau qhov tiav ntawm lub veneer.

• Xav siv cov xov paj hniav los ntxuav cov pos hniav.

• Sim tsis txhob haus cawv liab, tshuaj yej, kas fes, thiab txiv pos nphuab uas ua rau cov hniav dawb pigment.

• Tsis txhob tom cov khoom tawv.

• Nyob deb ntawm cov luam yeeb.
