Zirconia Bridge

Because of its qualities (strenght, durability and visual appealing), a zirconia bridge is considered a top quality type of bridge compared to other types of bridges.

Causing less tooth sensitivity and no sign of the dreaded grey line around the edge of the gums, this is often preferred to metal ceramic bridges, considering that for many people this is a downside of wearing a bridge. However, there is one solution to this problem: to choose an all ceramic bridge or the highly rated zirconia bridge instead.

Starting point: what is a zirconia bridge?

In order to better understand what is a zirconia bridge, for the beginning we should clarify one important thing: what is a dental bridge? This is a structure in which a false tooth and two crowns are attached to a metal base which acts as a replacement for missing teeth. As for the false tooth, it ‘bridges’ the gap in your teeth. How? It sits in the gap and is flanked by the two crowns which fit over the natural teeth on each side of the gap. In other words, it ‘bridges’ the gap in your teeth.

Deepening the subject, a zirconia bridge is different in that it is produced from Zirconium oxide – a tough form of dental ceramic which is also compatible with the body. Considering that the main problem with metal based bridges as there are people who have an allergy to the metals used in the bridge, the zirconia bridge is perfect because the body will not reject or react in a negative way to the bridge and, in addition to that, a zirconia bridge has a translucent appearance and is an ideal match with the rest of your teeth.

What is the process, how is a zirconia bridge fitted?

No matter what, first of all, your dentist will assess the current state of your teeth before discussing the pros and cons of the treatment with you and after that the process for fitting a zirconia bridge is the same as for any other type of bridge.

Following this procedure, the dentist will prepare your teeth for this bridge, this preparation stage being part of a two stage procedure: first stage is taking an impression of the affected teeth along with supporting x-rays, and the second stage is known as ‘tooth reduction’. For those who have no idea what this means, in this process the dentist trims the affected teeth with a small drill so that it will enable the crowns to fit over the top.

All these data are sent to a dental laboratory that produces your bridge over a period of two to three weeks, time in which you will wear a temporary bridge, in order to fell confortable.

After the zirconia bridge is ready for you, your dentist will fit it and check that it is a correct fit before cementing it in place. As expected, the dentist will advise you about looking after your bridge.

Which are the benefits of a zirconia bridge?

A zirconia bridge isn’t just stable, strong and incredible great looking which blends in well with the rest of your teeth, but it is also ‘biocompatible’, meaning that is kind to living tissue within your body and will not cause any ill effects or allergic reactions.

Sounds good, isn’t it? Well, that’s not all because zirconia brideges comes with even more advantages for you. This advantages includes less preparation, which refers to the process you undergo before the crown is fitted. Next to that, there is no metal base within this bridge which means no ugly looking black line at the edge of the gums which is a common feature of metal ceramic bridges.

Good, but are there any disadvantages or risks of this bridge?

As expected, everything good comes with some less good and one of the main disadvantages of the zirconia bridge is the cost considering that is more expensive than the standard metal ceramic bridge.

Despite the fact that ceramic is a tough, long lasting material, what can happen is that the surface of the crowns becomes rough which then rubs against natural teeth? Unfortunately, this causes them to become worn down and less effective than before. 

Another major issue is that all ceramic bridges can be less resistant to stress or extra forces, compared to metal ceramic bridges. Even if the newer varieties have a stronger inner structure, there is an increased risk of chipping or a fracture as a result of this.
