Kev ua tau zoo ntawm Zirconia Ceramics
Jun 16, 2022
Vim nws cov khoom zoo heev, zirconia ceramics tau dhau los ua qhov chaw kub hauv kev kawm ntawm cov khoom siv qhov ncauj hauv xyoo tas los no. Zirconia ceramics yog ib hom tshiab ntawm cov khoom siv zoo nkauj nrog cov khoom siv zoo (pob txha toughness, lub zog, hardness, thiab lwm yam), biocompatibility, stability, zoo nkauj, thermal conductivity thiab formability, uas yuav ua tau ib tug zoo tshuaj rau cov pa txhua yam-ceramics. Qhov teeb meem ntawm tsis txaus lub zog thiab toughness ntawm cov ntaub ntawv yas.
Lub toughness ntawm zirconia tag nrho cov-ceramic crown restorations uas tau siv kho mob kom deb li deb yog piv rau cov hlau thiab cemented carbide, thaum lub pob txha toughness thiab flexural zog yog li ob zaug siab li cov alumina ceramics. Cov khoom siv zoo heev ntawm zirconia ceramics ua rau muaj teeb meem ntawm qhov tsis muaj zog, tsis muaj kev cuam tshuam tsis zoo thiab siab brittleness ntawm cov khoom siv ceramic hauv qhov ncauj, tsim kom muaj qhov yuav tsum tau ua ua ntej rau lawv daim ntawv thov thiab kev txhawb nqa hauv qhov ncauj prosthodontics.
Tsis tas li ntawd, vim yog qhov chaw lom neeg lom zem nyob rau hauv lub qhov ncauj kab noj hniav, nws yuav tsum muaj tshuaj lom neeg ruaj khov zoo li cov khoom siv hauv qhov ncauj. Raws li ib qho zoo heev biologically inert ceramic, zirconia nthuav tawm cov tshuaj lom neeg ruaj khov zoo li lub qhov ncauj prosthesis lossis cog, thiab ua tau raws li cov qauv raws li cov khoom siv hauv qhov ncauj.
