1. Kev zoo nkauj ntawm cobalt chromium alloy porcelain fused rau cov hniav hlau tsis txaus. Piv nrog rau cov hniav ib txwm, cov tsos ntawm tag nrho cov hniav ceramic yog ze dua.
2. Cobalt chrome plooj (porcelain hniav) tseem yog cov hlau plooj (porcelain hniav). Txawm hais tias qhov teeb meem ntawm gingival xim blackening tau raug txhim kho, vim tias cov hlau tseem muaj peev xwm ntawm oxidation discoloration, tsawg tus neeg yuav muaj teeb meem ntawm cov kab gingival dub, uas yuav cuam tshuam rau kev zoo nkauj ntawm cov hniav.
3. Lub peev xwm bearing yog txwv. Koj tsis tuaj yeem tom tej yam nyuaj. Lub hardness tsis zoo li zirconia porcelain hniav.
4. Cobalt chrome porcelain hniav muaj hlau, uas yuav ua rau cov txiaj ntsig ntawm kev kho mob (xws li nuclear magnetic resonance) tsis raug.
