IPS Emax Press Crown yog qhov zoo tshaj plaws kho hniav kho hniav tsim los ntawm lithium disilicate iav -ceramic, muaj npe nrov rau kev sib xyaw ua kom muaj zog thiab zoo nkauj. Nws cov khoom tseem ceeb muaj lub zog flexural ntawm kwv yees li 360 MPa, ua rau nws haum rau ob qho tib si sab hauv (pem hauv ntej cov hniav) thiab tom qab (molar / premolar) cheeb tsam, tab sis zoo tagnrho rau cov neeg mob uas muaj zog occlusal.
Qhov zoo tshaj plaws yog nws lub ntuj translucency thiab xim versatility- muaj nyob rau hauv ntau qhov ntxoov ntxoo nrog cov txheej txheej staining xaiv, nws ua raws li lub teeb pom kev zoo -cov khoom ntawm lub ntuj enamel, tseem ceeb rau kev zoo nkauj luag ntxhi. Ua hlau -dawb, nws tshem tawm cov kev pheej hmoo ntawm kev tsis haum tshuaj rau cov hlau xws li npib tsib xee lossis chromium, thov rau cov neeg mob uas muaj kev nkag siab zoo.
Fabrication muaj xws li ib tug precision tshav kub- txheej txheem nias: molten ceramic yog txhaj rau hauv pwm kev cai nyob rau hauv qhov kub thiab txias, xyuas kom meej haum. Kev luam theej duab digital feem ntau txhim kho qhov no, txo qhov yuam kev piv rau cov txheej txheem ib txwm muaj. Ncej - nias, nws ua rau staining thiab glazing los kho cov xim thiab kev ntxhib los mos, txhim kho lifelikeness.
Muab piv rau zirconia crowns, nws muaj superior translucency (zoo dua rau cov hniav pom) tab sis me ntsis qis zog, yog li nws yog contraindicated rau loj bruxism los yog posterior txuas hniav xav tau heev durability. Nws yuav tsum tau txo cov hniav me me, khaws cia cov enamel noj qab nyob zoo, thiab tiv thaiv cov quav hniav, pab kom ntev - lub qhov ncauj noj qab haus huv. Kev ua tau zoo ntawm kev kho mob yog nyob ntawm kev npaj kom zoo (tsim ceramic thickness) thiab tsis txhob muaj zog ntau dhau los ntawm cov zaub mov tawv. Kev ntsuam xyuas tsis tu ncua pab tshawb xyuas cov chips thaum ntxov, tswj nws lub neej ntev.
