Metal free Dental Implants

Posted by: Barbara on February 7th, 2011 no responses.

Conventional dental implants contain a metal screw, which is inserted into the bone to form a root-like base for the artificial teeth. The most commonly used metal for this purpose is titanium, which exhibits several desirable properties including high strength, light weight, corrosion resistance.

Although titanium implants have high rates of success, the search for newer implant materials has been carried out widely.  Scientists have been looking for cheaper, more esthetic alternatives to this expensive metal. And, with some success, they have found an alternative in Zirconia.

 

Zirconia implants have been around for a few years, especially in the European market. However, they are still a new entrant in the field, and are yet to be completely passed as acceptable replacements for titanium implants.

 

The Zirconia dental implants are made of special ceramic (Zirconium oxide, ZrO2), which is known for its high resistance to fracture and heat. Not only are some of the properties comparable to titanium, these implants also have several advantages over it.
Zirconia has paved a new way metal-free implant dentistry, which is a boon for people who are allergic to metals, or cannot sport them for some other reason.

 

Getting dental implants is not a child’s play. It’s an investment in itself. In the first world nations many patients delay this procedure fearing the heavy bills that would reach them by the end of the procedure.

 

Fortunately with development of Dental Tourism, people now have options to choose from to get over their dental problems. Affordable dental treatments abroad have made things work for the patients who are seeking reasonably tagged dental implants procedure.

 

Zirconia implants surpass titanium in the following aspects:

 

Esthetics: While titanium has a dark, metallic color, Zirconium is whitish in appearance. Though most part of the implant is embedded within the bone, titanium sometimes shows a dark line around the gums. There is no such issue with Zirconia.

 

Hygiene: Ceramic implants and crowns are known to retain less plaque and calculus than titanium. So, they help the patient maintain better standards of oral hygiene and promote healthy gums.

 

Biocompatibility: Zirconium has decent biocompatibility; it is an inert material with very low allergic potential.

 

Corrosion Resistance: Zirconia tooth implants have almost a negligible risk of corrosion.

 

Patient comfort: Some patients are sometimes apprehensive about the idea of having a metal piece fixed into their bone. Ceramic implants solve this problem and provide patients with a comfortable option.

 

Osseointegration: Various studies have suggested that Zirconium implants with modified surfaces can integrate with the bone just like titanium.

 

Risks associated with Zirconia implants

Zirconia Dental Implant

Zirconia implants are relatively new to the market, and are still being highly probed for the associated risks and problems.

 

One of the major risks with these implants is radioactivity. Zirconium may contain a certain number of radioactive isotopes, the activity of which may lead to an increased chance of various oral cancers.

 

Usually the Zirconia used in implants has extremely low radiation emission levels, and manufacturers of these are required to produce a declaration of radioactivity for their Zirconium based dental products.

 

Patients looking to get Zirconia implants must ensure they discuss all possible options with their dentist before undergoing any surgical procedure. One could also find free quote online which could help him plan his budget accordingly. Getting dental implants in India, Mexico, Thailand or Costa Rica could be favorable and one could also save a lot on the procedure.
