Simple comparison between porcelain VS zirconia teeth

Cobalt-chromium porcelain dental crown:

Real non-precious metal porcelain teeth full crowns, cobalt-chromium porcelain teeth were first-used to make artificial joints, with outstanding biocompatibility, and have been widely-used in the field of dental restorations, safe, reliable, reasonably priced, and stable in performance.

advantage:

Good biocompatibility, high strength, economical value and high cost performance.

shortcoming:

After the metal is oxidized, gray oxides will be formed, and black gum lines will appear.
Because it contains metal components, it is generally not possible to do MRI directly. MRI CT can be performed only after the porcelain teeth are removed.
There is metal, so the color is unnatural and the aesthetics is low. Not recommended for use on front teeth.
Light transmittance and aesthetics are average.
Need to grind teeth.

Applicable symptoms:

Unable to perform dental implants.

Contraindications

The patient has the habit of biting deeply, grinding teeth, and gnawing hard food.
The patient has oral inflammation or periodontal disease.
All-ceramic crowns (Zirconium dioxide all-ceramic teeth):

All-ceramic zirconium crowns are dentures that do not contain a metal layer at all, and are completely made by cutting and firing ceramics. Because of the lack of unsightly metal layers, all-ceramic dental crowns are the most perfect and natural dentures today. Transparent and beautiful like teeth.

advantage:

Good light transmittance and aesthetics, closer to the color of natural teeth
The comfort is higher, without the hard texture of metal, the material is closer to the hardness of tooth enamel.
It has good biocompatibility, does not contain metal components, and will not cause allergic reactions and irritation of the gums.
MRI can be done without removing the crown
Hard and wear-resistant, high compression resistance.

shortcoming:

The price is more expensive than porcelain dental crowns.
Need to grind teeth.

Applicable symptoms:

All-ceramic zirconia crowns can be used to restore the teeth whose root canal treatment is completed or whose defects are too large.
Unable to perform dental implants.
