1. The aesthetics of cobalt chromium alloy porcelain fused to metal teeth is insufficient. Compared with normal teeth, the appearance of all ceramic teeth is closer.
2. Cobalt chrome porcelain teeth still belong to metal porcelain teeth. Although the problem of gingival color blackening has been improved, because the metal still has the possibility of oxidation discoloration, very few people will have the problem of black gingival line, which will affect the aesthetics of teeth.
3. The bearing capacity is limited. You can't bite hard things. The hardness is not as good as zirconia porcelain teeth.
4. Cobalt chrome porcelain teeth contain metal, which will make the results of medical imaging (such as nuclear magnetic resonance) inaccurate.
