Yuav ua li cas xaiv los ntawm All-ceramic hniav, porcelain hniav, hlau hniav?

 

Kuv yuav ua li cas yog kuv cov hniav puas lawm?

Cov lus teb yog kom tau DENTURES.

Cov hniav hlau, cov hniav plooj (porcelain), thiab cov hniav txhua-ceramic yog peb hom kev kho hniav uas nrov tshaj plaws.

Peb yuav xaiv li cas los ntawm cov ntaub ntawv no?

 

 

Nqe thiab Aesthetics

 

★ Hais txog tus nqi, feem ntau, cov hniav hlau yog qhov pheej yig tshaj plaws, thaum tag nrho cov hniav ceramic yog kim tshaj plaws.

Qhov zoo thiab qhov tsis zoo

 

 

Hlau yog cov khoom siv niaj hnub rau kev kho hniav kho hniav thiab tau siv ntau xyoo lawm. Tam sim no feem ntau siv yog cov hlau muaj txiaj ntsig thiab cov hlau tsis muaj nqi. Cov hlau muaj txiaj ntsig muaj xws li kub alloys, kub-palladium alloys, nyiaj-palladium alloys, thiab lwm yam, thiab cov hlau tsis muaj nuj nqis suav nrog nickel-chromium alloys, cobalt-chromium alloys, titanium thiab titanium alloys.
Qhov zoo ntawm cov hniav hlau hlau yog lub zog siab, muaj zog thiab hnav-resistant, txheej txheem yooj yim thiab tus nqi qis. Tab sis qhov tsis zoo kuj pom tseeb. Lawv tuaj yeem pom tau yooj yim hauv lub qhov ncauj, uas tuaj yeem ua rau lawv sawv thiab cuam tshuam los ntawm tus neeg lub ntsej muag tag nrho. Lwm qhov tsis zoo ntawm cov hniav hlau yog tias lawv tsis tas li biocompatible. Qee tus neeg yuav ntsib kev tsis haum tshuaj lossis lwm yam kev mob tshwm sim tsis zoo los ntawm cov hlau hauv lawv cov hniav, uas tuaj yeem ua rau tsis xis nyob lossis txawm tias kis tau.

Cov hniav hlau xav tau kev saib xyuas tshwj xeeb thiab tu kom lawv saib thiab ua haujlwm zoo tshaj plaws.

Nws tuaj yeem siv ob qho tib si lub zog thiab kev zoo nkauj rau hauv tus account. Nws muaj ob lub zog ntawm cov hlau thiab cov xim ntawm cov plooj (porcelain).

Raws li cov khoom siv hlau sab hauv, cov hniav plooj (porcelain hniav) tau muab faib ua cov hniav nyiaj hniav kub uas muaj nuj nqis thiab cov hniav uas tsis muaj nuj nqis hlau plooj (porcelain hniav). Clinically feem ntau siv kub alloy porcelain, cobalt-chromium alloy porcelain, npib tsib xee-chromium alloy porcelain thiab lwm yam.

Thaum ua hniav hniav, ib feem ntawm cov hniav ntuj yuav tsum tau muab pov tseg, thiab tom qab ntawd cov hniav yuav tsum tau muab tso rau, thiab cov hniav uas yuav tsum tau muab pov tseg yog ntau tshaj li cov hniav hlau, vim cov hniav porcelain yog tuab ( hlau ntxiv porcelain) thiab xav tau qhov chaw ntxiv.
