CovCobalt-Chromium (Co-Cr) Alloy Cast Frameworkyog lub hauv paus tseem ceeb hauv kev tshem tawm ib feem ntawm cov hniav hniav (RPD) kev tsim khoom, muaj nuj nqis rau nws qhov kev pom zoo ntawm kev ua haujlwm zoo thiab biocompatibility hauv kev kho hniav prosthetics.
Manufactured los ntawm classicpoob -wax casting txheej txheem, nws muab qhov tseeb qhov tseeb, qhov tseem ceeb rau seamless adaptation rau qhov ncauj qhov ntswg. Tsis zoo li cov ntshiab titanium los yog kub alloys, Co-Cr alloys muab superior tensile zog thiab corrosion kuj ntawm tus nqi -zoo nqe taw tes, ua rau lawv nyiam xaiv rau kev kho hniav labs thoob ntiaj teb. Ua raws liISO 1562: 2019 Daim Ntawv Pov Thawjcov qauv, cov qauv no ua tau raws li cov kev cai biocompatibility nruj, txo qhov kev pheej hmoo ntawm cov nqaij mos ntawm qhov ncauj txawm tias ntev - cov neeg hnav.
Ib qho tseem ceeb ntawm kev txiav txim siab yog qhov ua tiav ntawm qhov chaw: qhov chaw du ua rau tus neeg mob xis nyob, thaum tus qauv tsim ntxeem tau ua kom cov resin bonding zog- qhov tseem ceeb rau kev txhawb nqa ntau cov hniav hniav hauv siab - mastication - load case. Clinically, Co-Cr cast frameworks excel nyob rau hauv rooj plaub uas cov neeg mob yuav tsum tau check, hnav RPDs, tshwj xeeb tshaj yog rau tom qab hloov hniav.
Tshwj xeeb tshaj yog, piv rau 3D- luam tawm Co- Cr moj khaum, cam khwb cia versions ua kom pom kev qaug zog zoo dua nyob rau hauv lub zog zom zaws, txawm tias 3D luam ntawv muaj kev hloov pauv sai rau cov duab geometry nyuaj. Kev saib xyuas kom raug- suav nrog kev tu thiab kho cov neeg ua haujlwm tsis tu ncua- txuas ntxiv lub hauv paus kev pab cuam lub neej mus rau 5-8 xyoo nyob rau nruab nrab, ua kom nws cov xwm txheej zoo li qhov tseem ceeb hauv kev kho hniav kho hniav.
