Zirconia rov kho dua
Peb CAD \/ CAM Zirconia Thaiv yog cov khoom siv zoo, cov khoom siv zoo nkauj nrog cov khoom zoo nkauj, uas yog cov khoom zoo meej los ua kom koj cov tsiaj muaj peev xwm.
Kawm ntxiv txog cov khoom:Hniav Zirconia block
Hniav Zirconia
Zirconia dis yog ib qho kev ua tau zoo tag nrho cov khoom siv zirconium oxide hmoov thiab cov khoom tsim nyog ntawm cov khoom ruaj khov los ntawm kev tshaj lij sintering txheej txheem. Cov khoom muaj ntom ntom heev thiab khoov tau muaj zog, ua kom nws tseem nyob ruaj khov thiab ruaj khov thaum lub sijhawm zom. Nws lub xeev pre-sintered yog yooj yim rau kev koom tes nrog kev ua kom muaj kev ua tiav thiab tau raws li cov kev xav tau ntawm ntau lub crowns, txuas hniav thiab puv-qhov ntswg rov qab. Zirconia dis muaj kev ua tau zoo tshaj plaws. Nws cov xim gradient muaj xim zoo nkauj thiab lub teeb kev hloov kho zoo tuaj yeem txig zoo dua lub zog kho qhov muag ntawm cov hniav ntuj. Nws muaj biocompatibility zoo heev thiab tsis yooj yim rau qhov ua rau cov kev tsis txaus siab uas ua rau cov tshuaj tiv thaiv kab mob. Strict quality inspection systems and international certifications ensure that each piece of Zirconia Disc meets the standards of high-end dental restoration materials, providing safe, stable and precise material guarantees for clinical use.
