How durable are zirconium crowns?

Zirconium is a strong material used even in medical applications requiring high durability, such as hip replacements. Therefore, it maintains its durability for many years in teeth. It is highly resistant to the forces of chewing in daily use and is very unlikely to break. Of course, habits such as biting hard objects and clenching teeth can pose long-term risks. However, with proper planning, good laboratory work, and regular dental care, zirconium crowns can last 15 years or more.
