Zirconia Material for Crowns and Restorations
Reasons for the growing popularity of zirconia material for crowns and restorations.
Zirconia is today the preferred material when it comes to crowns and dental restorations. As compared to metal crowns and porcelain fused to metal restorations zirconia crowns are considered to be a much better option.
Whether it is single tooth restoration or fixed dental prostheses, dental practices are switching to zirconia. This is a metal oxide that is derived from zirconium and it is used in the making of some household items.
Reasons that have made zirconia the material of choice for dental restorations:
- Superior strength of zirconia:
One of the main reasons that zirconia is considered the best material for making crowns is its exceptional strength. Zirconia is highly robust and hence it does chip when subjected to wear and tear.
So whether it is mastication or bruxism one need not be worried about chipping of the crown if it is made from Zirconia. The crowns used in the posterior region have to be very strong so that there is no problem in mastication and here zirconia is the material of preference.
These days solid blocks of zirconia that are monolithic zirconia is used which makes the crown rigid and can even withstand harsh conditions.
- Zirconia has excellent aesthetics:
At the gingival margin, no metal lining is used in the case of zirconia crowns. So as far as aesthetics is concerned zirconia is one of the best options. It helps to bring back that confident smile of the patient as there is no metal lining involved in the case of crowns made from zirconia.
- Customization is so easy when it comes to zirconia:
Customization of the crowns made from zirconia can be done easily and they can be made of any fit, size or shape so that they match with the other teeth of the patient.
Due to aspects like the chemical composition or the processing requirements, it is possible to manufacture these crowns as per the specific needs of patients. The margin of error reduces due to the customization and crowns that fit well can be manufactured with ease using zirconia.
- The safety aspect of zirconia:
One very crucial reason for using zirconia crown is the safety aspect. Allergic reaction probability is highly reduced due to the high biocompatibility of zirconia. The dental restorations that are made from zirconia are safe for clinical use.
- Unmatched durability of zirconia:
As compared to the conventional PFM ceramic zirconia crown is found to be more durable. Since this material has more stabilizers it can easily withstand grinding and mastication. With proper care, these dental restorations can last for many years.
