Caring for Zirconia Crowns

Zirconia does not corrode due to the ceramic material, so it can last for several years. Although it is not subject to decay, it is best to brush it and your natural teeth at least twice a day using a soft-bristled toothbrush and nonabrasive toothpaste.

Can you adjust zirconia?

Zirconia is harder and stronger than most metals used for crown and bridge procedures. As such, it can be exceptionally difficult to adjust appropriately with standard instrumentation. For the best results when working with zirconia, you should rely on instruments optimized for the high-strength material.

Can zirconia crowns be repaired?

Zirconia-based crowns fared just as well over the course of 5 years as metal-based crowns, according to a 2017 randomized controlled trial published in the Journal of Dentistry. And crowns made of zirconia, called monolithic zirconia crowns, are especially durable.

Is Zirconia better than porcelain?

Zirconia offers superior strength and durability for dental crowns. It is at least three times stronger than porcelain or PFM restorations. Unlike porcelain, zirconia can withstand wear and tear without chipping, which is why zirconia restorations tolerate extreme chewing and bruxism.

How do you fix a zirconia?

Place a tooth desensitizer/disinfectant on the tooth preparation and suck it off (don’t wash it off). Place a bonding agent on the internal of the restoration and on the external of the tooth preparation, then seat with a self-adhesive or adhesive cement as identified previously.
