Cobalt-chromium (co-cr) corsalin-Fused-to-hlau DentalsinS sawv cev rau kev ua haujlwm tseem ceeb hauv kev ua haujlwm thiab kev pheej yig. Tus co-c alloy, feem ntau tsim ntawm cobalt, chromium, thiab me me ntawm molybdenum thiab tungsten, ua pov thawj tshwj xeeb cov khoom siv tshuab. Nws lub zog siab-rau-hnyav piv ua kom cov yas, tsis tau siv tus hniav txo ntau dhau thaum npaj. Ntxiv mus, lub alloy zoo heev corrosion tawm tsam kom muaj kev ruaj khov nyob rau hauv lub noo, inquiding qhov ncauj ntawm kev rov qab los.
Nyob rau hauv cov nqe lus ntawm biocompatibility, co alloys muaj qis dua npib tsib xee cov ntsiab lus piv rau cov hlau laus alloys, txo kev tsis haum xeeb. Txawm li cas los xij, cov teeb meem rhiab tseem tuaj yeem tshwm sim, tshwj xeeb hauv cov neeg mob uas muaj cov hlau ua xua. Cov txheej txheem tsim khoom lag luam cuam tshuam txog precision casting ntawm alloy moj khaum Qhov laj thawj no tsim ib qho chaw zoo uas ua rau cov xim thiab kev txhais cov hniav tiag tiag, txhim kho cov kev tswj hwm masticatory.
Txawm hais tias lawv tau zoo, CAL-CR yass muaj kev txwv. Sij hawm dhau mus, cov hlau txuas mus yuav ua rau muaj kab mob greyish discoloration ntawm cov kab ntawm cov pos hniav, tshwj xeeb tshaj yog hauv cov neeg mob nrog nyias gingiva. Ib qho ntxiv, daim phiaj hniav yuav nti tau nti tau nti tau nti tau nti tau nti tau nti tau nti tau nti lossis kev sib tsoo nyob rau hauv cov tub rog ntau qhov kev siv, xav tau kho lossis hloov. In the evolving dental market, Co-Cr crowns remain a popular choice for posterior teeth restorations due to their cost-effectiveness, but their use is gradually declining as more advanced materials like zirconia gain traction. Txawm li cas los xij, kev nkag siab co-cr yass tseem ceeb heev rau cov kws kho hniav, vim lawv txuas ntxiv mus ua lub qhov ncauj kho mob.
