Zirconia Crowns - The most aesthetic crowns available
The look of Zirconia crowns and bridges are so close to natural teeth that it is hard to tell the difference.
A Zirconia crown is a popular type of all-ceramic crown which is worn to improve the appearance of a tooth which has become stained or disfigured over the years. They are durable, easy to wear and long lasting. In addition, Zirconia crowns have a translucent appearance which means that they are indistinguishable from your own teeth. It is hard to spot a Zirconia crown amongst natural teeth.
Zirconium is one of the oldest and most abundant elements in the terrestrial crust and it is the basis for Zirconium oxid. It is a very strong material which is compatible with the human body. Zirconia is used in many other medical applications such as artificial joints and is known for its strength and durability. Zirconia is a type of crystal which is long lasting and indestructible.Zirconia crown is safe to use and preferred by many people to porcelain fused to metal crowns.
Zirconia crowns are extraordinary strong and can withstand most chewing and biting activities. They are very resistible to high temperatures and, as a rule, don’t cause teeth hypersensitivity. Due to the fact that they are made of crystal, zirconium crowns are much stronger than porcelain and porcelain-fused-to-metal ones. Furthermore this very acid-proof material prevents the absorption of pollutants and makes cleaning easier and can last longer than other type of crowns.
It is hard to differentiate a Zirconia crown amongst natural teeth. In addition, Zirconia crowns can be modified, according to the shape and size of teeth it will be placed alongside with. These crowns have an attractive translucent colour which blends in well with the other teeth. These crowns are translucent and smooth, matching the size, color and shade of your original teeth therefore are a perfect choice for attractive front teeth restorations.
Due to their biocompatible structure, Zirconia crowns rarely provoke allergic reaction or gum irritation.
⇒Retain more of the existing tooth
Minimal preparation is required which means more of the original tooth is preserved. This is also useful if the crown needs to be removed.
⇒No dark line
Unlike porcelain-fused-to-metal crowns (PFM), all-porcelain crowns don’t have a problem of a dark line as they all made of white porcelain that perfectly imitates your natural tooth enamel. There are no black margin in case of age-related retreat of the gums, as this might be the case with metal restorations.
The process is similar to that for other crowns. It involves two stages: preparation (first stage) and the fitting of the crown (second stage).
- Preparation and Impression
The first stage is where your teeth are assessed and measured for a crown. The dentist will discuss the procedure with you before preparing your affected tooth. This preparation involves the cleaning of the tooth before reshaping with a small drill. A small sliver of tooth is removed under a local anaesthetic which ensures that the tooth is the correct shape for the crown. A mould is made with dental putty which you will be asked to bite into. This is used as a guide for the production of your new crown at a dental laboratory.
The second stage is where you will be fitted with your new crown. The tooth which will receive this crown is roughened with a special dental acid which scratches the surface and increases the bond between crown and tooth. The crown is then fitted onto your tooth. Your dentist will check its appearance and fit before cementing it into position. It is then given a final polish.
Dental crowns require the same level of care and attention as your natural teeth.
- Brush your teeth after each meal and before bedtime, especially at the gum line.
- Floss at least once or twice a day.
- Rinse with fluoride rinse before bedtime.
- Visit your dentist for regular check-ups and professional cleanings.
The life of a crown will depend on how well it is looked after. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth. It is very important to keep this area as clean as your other teeth, or decay may occur which could endanger the crown.
