Cov Hniav Kev Hniav FMC FMc Tag Nrho Cov Hlau

TusDental FMC (Puv Steel yas)Yog lub zog ua kom ruaj khov, muaj zog kho cov khoom siv rov qab los ntawm cov khoom siv kho hniav zoo li kub-palladium, semi-precious alloys, lossis npib tsib xee-chromium). Tsim los rau ib leeg-hniav lossis cov hniav yooj yim, nws muaj cov qauv hlau ruaj khov uas tag nrho cov hniav npaj ua kom ruaj khov thiab tiv thaiv tsis muaj zog. Cov ntsiab lus tseem ceeb muaj xws li:

Superior zog: Qhov zoo tagnrho rau cov hniav posterior hauv cov pa hluav taws xob zoo siab (piv txwv li, cov hniav puas nrog cov neeg mob bruxism, nrog cov khoom siv bruxism ntau tshaj 800 MPa.

Precision haum: Siv lub tshuab poob los yog CAD \/ Cam tshuab los xyuas kom ntseeg tau kev ncaj ncees thiab tsawg dua micrork.

Biocompatibility: Noble Hlau Variants Muaj Kev Zam Cov Ntaub Ntawv Zoo Tshaj Plaws, txo cov khaus sib tw tau piv rau cov hlau hluav taws xob.

Kev muaj peev xwm: Ua pov thawj 10+ xyoo lub neej muaj sia nyob rau hauv chaw kuaj mob, ua rau kev xaiv txhim kho kom tau txais kev rov kho dua tshiab.

Thaum tsis muaj kev pom zoo kom zoo nkauj ntawm txhua-ceramic crowns, FMCs Excel nyob rau hauv cov ntaub ntawv durability, piv txwv li cov khoom noj ntxiv rau hauv thaj chaw tsis pom). Tsim nyog tsim nyog suav nrog kev txo qis ntawm 1.5-2. {5}} hli thiab nqus plua plav thiab kev faib tawm.

Vim li cas FMCs tau nyiam rau cov hniav pos hniav lossis mob siab?

FMCS (tag nrho cov hlau nplaum) yog nyiam rau cov hniav postorior lossis cov khoom siv ntxhov siab vim lawv cov kev ntseeg siab muaj txiaj ntsig thiab cov qauv kev cai. Lawv liLub zog flexural, feem ntau tshaj800 MPa, muaj kev xaiv tag nrho cov kab ke zoo li lithium disilicate (360-470 MPA) thiab txawm tias rov qab zirconia raws li kev hloov pauv hauv cov xwm txheej ntxhov siab. Lub zog zoo tshaj plaws ua rau lawv tsis tseem ceeb rau:

Kos ntsiab lus kos npe(Cov hniav puas thiab cov ua ntej), qhov chaw ua rau cov rog thaum ntuj pib ntau tshaj thaum zom mov (piv txwv li ntawm 400-700 n hauv cov hniav puas). Cov khoom siv hlau cov qauv no faib cov rog no, txo qis kev pheej hmoo ntawm CUSP pob txha lov lossis rov qab ua tiav.

Cov neeg mob uas muaj kev ua kom parafununctional(Bruxism, zawm), leej twg tsim ntau dhau, tsis muaj lub cev rog. FMCS ua yeeb yam ruaj khov rau rov ua kom sib tsoo, tsis zoo li cov hlau nplaum sib tsoo, uas yog nquag rau cov ceramic chipping lossis Delamination nyob rau hauv cov kev ntxhov siab ntawd.

Kev ntseeg tau ntevNyob rau hauv cov hniav looj kev cuam tshuam (piv txwv li, txuas ntxiv lwj lossis endodontically kho cov hniav puas), qhov twg cov qauv kev txhawb nqa yog qhov tseem ceeb. Qhov tsis muaj ntawm cov khoom sib xyaw ceraminates tshem tawm cov khoom noj uas tsis muaj zog hauv hybrid rov qab, ua kom muaj kev ncua ntev txawm nyob hauv ib puag ncig lub siab.
Clinically, Qhov no ua rau FMC cov qauv kub rau cov khoom lag luam zoo tshaj plaws uas yuav tsum muaj lub zog ntau, tshwj xeeb hauv cov rooj plaub uas muaj lub zog ua haujlwm ruaj khov.
