Yam khoom siv kho hniav Crown / Veneer: Zirconia lossis Emax?

Pa PFM (Porcelain Fused to Metal) tau hloov pauv los ntawm ntau qhov kev zoo nkauj thiab zoo nkauj zoo nkauj. Zirconia thiab Emax crowns yog cov qauv tshiab hauv kev kho hniav kom hniav zoo nkauj thiab lawv cov koob meej nce zuj zus mus ib hnub. Txawm li cas los xij, xaiv cov khoom siv kho hniav zoo rau koj cov hniav tej zaum yuav tsis meej pem.

Yam khoom siv kho hniav twg zoo dua rau kuv cov hniav?

Kev xaiv ntawm cov khoom siv kho hniav yog nyob ntawm qhov chaw lawv tau siv. Piv txwv li, thaum E-max veneers nyob rau hauv Qaib Cov Txwv yog zoo meej rau pem hauv ntej cov hniav, lawv yuav tsis yog qhov zoo tshaj plaws kev xaiv rau molars. Cia peb saib kom ntxaws ntxiv ntawm lawv qhov tseem ceeb.

A- PFM Crowns

Porcelain Fused rau Hlau, raws li tuaj yeem nkag siab los ntawm lub npe, siv cov hlau alloy ua lub hauv paus. Porcelain uas yog qhov pom ntawm PFM crown yog tsim los ntawm cov xim tsaus nti ntawm lub hauv paus rau kev siv dag zog. Porcelain yog cov khoom siv translucent. Yog li ntawd, kev siv cov opaquer uas tiv thaiv cov xim tsaus nti ntawm lub hauv paus ntawm cov plooj (porcelain nto) yog ib feem thiab ib feem ntawm PFM cov hniav nyiaj hniav kub. Yog li ntawd, nws yuav nyuaj dua kom ua tiav qhov zoo nkauj ntawm cov hniav hniav.

B-Zirconium yas

Zirconia crowns yog ib qho khoom siv zoo tshaj plaws los hloov cov hniav hauv kev kho hniav niaj hnub. Zirconia yog cov khoom siv tawv thiab xim dawb. Txawm li cas los xij, muaj 3 ntau hom zirconia crowns muaj thiab nws yuav muaj txiaj ntsig zoo rau tus neeg mob kho hniav kom kawm txog lawv qhov sib txawv.

Tag Nrho Zirconia Crown

Txawm hais tias nws muaj zog thiab muaj cov xim zoo li cov hniav, zirconia yog cov khoom tsis zoo uas txhais tau hais tias nws tsis cia lub teeb hla, tsis zoo li cov hniav thiab cov plooj (porcelain). Yog li ntawd, tag nrho zirconia crowns tsis yog qhov kev xaiv zoo tshaj plaws los siv rau hauv qhov chaw tseem ceeb xws li incisors thiab canines. Vim lawv lub zog txhua yam, lawv tau siv ntau dua hauv cov hniav molar, uas yog nyob rau hauv ib qho kev thauj khoom thiab tsis tshua muaj qhov tseem ceeb.

Multi-Layered Tag Nrho Zirconia Crown

Yuav kom kov yeej cov teeb meem zoo nkauj txog Tag Nrho Zirconia Crowns, manifacturers tau pib tsim ntau txheej zirconia blocks. Cov Multi-layered Tag Nrho Zirconia Crowns muab cov txiaj ntsig zoo nkauj zoo dua li cov qauv zirconia blocks. Lawv tau siv tshwj xeeb hauv cov hniav hauv pem hauv ntej uas yog qhov tseem ceeb ntawm kev zoo nkauj thiab lawv muab cov txiaj ntsig txaus siab.

Porcelain Fused rau Zirconia (PFZ)

PFZ crowns muaj tib lub cev raws li PFM's; cov plooj (porcelain) yog tsim los ntawm cov khoom siv hauv paus. Txawm li cas los xij, cov xim ntawm zirconia puag siv hauv PFZ crown yog ze dua rau cov xim ntawm cov hniav, tsis zoo li PFM yas. Hauv Porcelain Fused rau Zirconia, kev sib xyaw ua ke ntawm zirconia puag thiab lub cev porcelain translucent muab cov txiaj ntsig zoo nkauj zoo nkauj. Yog li ntawd, lawv yog ib qho ntawm thawj qhov kev xaiv rau kev kho hniav kom hniav zoo nkauj.

C- Txhua-Ceramic Crowns & Emax

Emax yog ib hom tag nrho-ceramic crowns uas muab cov txiaj ntsig zoo nkauj zoo nkauj. Tawm tsam PFM thiab PFZ, Emax crowns tsis muaj cov khoom siv hlau. Yog li ntawd, tag nrho cov yas yog ua los ntawm ceramic. Emax crowns muab lub ntuj zoo tshaj plaws thiab lawv siv rau ntawm cov hniav pem hauv ntej xws li incisors, canines thiab premolars.

Txawm hais tias lawv muab cov txiaj ntsig zoo nkauj zoo nkauj ntawm cov hniav pem hauv ntej, Emax crowns tsis yog cov kev xaiv zoo tshaj plaws rau qhov chaw thauj khoom xws li cov hniav molar.
