Zirconia or metal-ceramic crown: which is better?

The main difference between a zirconia and a metal-ceramic crown is the base material. Zirconia is fully ceramic, with a natural look and no metal, while metal-ceramic has a metal core covered with ceramic. Zirconia offers the best aesthetics, while metal-ceramic remains a solid and more affordable option.

Why the material matters

With metal-ceramic, the metal core can leave a visible grey line at the gum over time, especially on front teeth. Zirconia has no metal, so it lets light pass similarly to a natural tooth and does not produce that grey line. For the visible front area, zirconia is usually the first choice.

Quick comparison

Aesthetics. Zirconia looks natural, with no grey line. Metal-ceramic is very good but may show a grey line at the gum over time.

Biocompatibility. Zirconia is fully ceramic and very well tolerated. Metal-ceramic contains metal, rarely with sensitivities.

Durability. Both are strong and long lasting. Modern zirconia withstands chewing forces very well.

Price at AURA DENT. A zirconia crown starts from 1500 RON, and a metal-ceramic one from 800 RON.

Our recommendation

For front teeth and for patients who want the most natural result, we recommend zirconia. For back teeth or when budget is the priority, metal-ceramic remains a very good solution. We recommend the right option after evaluating your smile and the position of the tooth.
