What is Zirconia?

Zirconium is a chemical element with atomic number 40 and symbol ‘Zr’ in the periodic table. It is known for its hardness, resistant to corrosion and various other properties similar to steel. It can’t be found in pure state in nature. However it can be obtained through complex physico-chemical process. In the periodic chart, it is located next to Titanium (Ti). For this reason their properties are very similar.

Which form of Zirconia is used in Dentistry?

Zirconium ceramic is obtained through a comprehensive cycles of reductive chlorination (Kroll process). At the end of this process, zirconium oxide powder is attained which is primary ceramic and remains no longer a metal.
ZIRCONIA is a powder that is also used as a pigment in various commercially available white paints, and also as abrasives. At room temperature it exists in a monolithic phase. This state of existence is extremely brittle and fragile.
To improve the properties of zirconia (ZrO2), other elements are added to the compound to stabilize the molecular structure: ex. Yttrium (Y). Through a mixture and sintering process, the final ceramic structure is stabilized and is known as Y-TZP (Yttrium stabilized Tetragonal Zirconium Polycrystal). The Y-TZP ceramic is the material that is used in dentistry as ZIRCONIA.
At Ankura dental hospital in addition to various dental specialties we possess that includes orthodontist, implantologist, cosmetic dentist, root canal specialist and oral surgeons, we also have one of the best in-house dental labs in Hyderabad reinforced with high skill proficient team of Lab Technicians who understands the A to Z of the various properties of zirconia and chooses the ones best suitable for your needs.

Applications of Zirconia in Dentistry?

Zirconia has already been extensively used over 40 years for both commercial and industrial purposes. It is highly biocompatible and exceptionally durable in longevity. For these favourable reasons it is used increasingly in surgery for ear, finger and hip prostheses. Applications for dentistry are found in zirconia crowns, bridges, dental implants and pins. The material’s natural white base allows individual colour blending in predefined dentin shades.
The biotechnical characteristics of zirconia result in high quality crowns, bridges and implants with excellent aesthetic appearance and biocompatibility.

What is a Zirconia Crown?

This type of crown is made from zirconia, 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.
Plus there is no fear about the body rejecting zirconia or displaying an allergic reaction to it. It is safe to use and preferred by many people to porcelain fused to metal crowns.
In addition to the advanced specialty dental services we also have best modern in-house dental laboratory that enables us to provide you the finest prosthodontic dental care by rendering you the best zirconia crown options available.
At Ankura dental clinic we take pride in presenting you to the best dental treatments in Hyderabad and with our wide range of zirconia crowns, you are sure to meet the highest dental care.

Advantages of a Zirconia Crown

Strength: zirconia crowns last longer than other types of crowns.
Aesthetics: these crowns have an attractive translucent colour which blends in well with the other teeth.
Retain more of the existing tooth: Minimal preparation is required which means more of the original tooth is preserved. This is useful if the crown needs to be removed.
So, a good choice if you are looking for a strong, long lasting and visually appealing crown. They are ideal at covering signs of damage or staining as well as helping to maintain the function of the tooth.
At Ankura dental hospital we understand your expectations and concerns towards esthetics and durability and hence we constantly strive to provide you the best cosmetic care available.

Disadvantages of a Zirconia Crown

The disadvantages of zirconia are negligible but yet worth mentioning.
The tough, durable nature of a zirconia crown can work against it as well as in its favour. This material has an abrasive quality which can cause friction against the root of the tooth as well as other teeth.
It must be highlighted that dental specialist in the field of prosthodontics are trained and qualified to make individual assessment of each patient and customize treatment plan using zirconia based prosthetics that can cater your functional and aesthetic demands. Hence at Ankura dental hospital, a comprehensive diagnostic assessment by our team of Prosthodontist must be done. We are one of the famous dental clinics which has an in-house Prosthodontic and implantology services to provide the necessary multidisciplinary approach your condition may need.

How is a Zirconia Crown Cemented?

The process is similar to that for other crowns. It involves two stages: preparation of tooth structure (first stage) and the fitting of the crown (second stage).
The first stage is where your teeth are assessed and measured for a crown. Our highly qualified and vastly experienced Prosthodontist will discuss the procedure with you before preparing your affected tooth. This preparation involves the cleaning of the tooth before reshaping (which reduces its size) 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 our dental laboratory which has the best standards of technical equipments with high precision.
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. The dentist will check its appearance and fit before cementing it into position. It is then given a final polish.

A zirconia crown must be cared for in the same way as your natural teeth. .
At Ankura dental clinic we lay emphasis in not just choosing the right zirconia property but also on its long term maintenance. With our systematic and well organized periodic recalls we monitor the service and integrity of your prosthesis. With our best dental quality and a high profile team of dentists, we commit our dental services to the highest standards. At Ankura dental clinic your comfort and satisfaction is our highest priority.

Replacement with metal-free/full zirconia restorations possible?

Replacement of conventional (precious) metal-based restorations with zirconia is entirely possible, but should only be carried out by dental specialist who have undertaken special training in this field.

Aesthetic comparison of zirconia vs. Conventional metal based crowns?

Zirconia framework is translucent and far superior to the opaque appearance of metal-ceramic. It delivers far more superior natural appearance with the adjacent teeth in comparison to the conventional metal based crowns.
Hence it is highly indicated for the replacement of front teeth for its esthetic properties while suggested for back teeth primarily owing to its high strength and durability.

How does cost compare with metal-ceramic?

Zirconia restorations are equal to or marginally more expensive than metal-ceramic restorations.
At Ankura dental clinic our team of prosthodontic specialist will customize the best dental treatment tailor-made for your case following detailed assessment of the risk and complications expected by the treatment plan and other underlying factors you may have.
