Upside to Having Zirconium Dental Implants


A perfectly aligned set of white, healthy and beautiful teeth is essential to looking your best and boosting your self-confidence. Some people are blessed naturally with straight and sparkling teeth but who aren't lucky enough to have two lines of pearly whites can still flash a fabulous smile with the help of dental implants.



Unlike removable dentures, dental implants never slip or make embarrassing sounds. As well, they look and feel like natural teeth and serve as long-term replacements. Composed of titanium metal that fuses with your jawbone, dental implants preserve the health and function of the jaw.

Titanium implants are the most extensively used teeth restorations in the field of dental implantology today, thanks to their impressive success rate i.e. 98% for lower implants and 91% for upper implants.

However, recently, non-metallic material implants have been introduced to replace a tooth or several missing teeth. The new form of teeth implants, called zirconium dental implants, offers a potentially more precision, strength, and aesthetic appeal than traditional titanium implants.

Overview of Zirconia

A clear definition of zirconia is needed when looking into zirconium dental implants. Zirconium dioxide (ZrO2), commonly known as zirconia or simply "white steel," was discovered back in 1789 by the German chemist M. H. Klaproth. Today, zirconia is extensively used in automotive and aircraft industry because it is extremely resistant to heat and corrosion. This so-called 'wonder material' possesses some remarkable properties such as high bending strength, hardness and weibull modulus.

Thanks to its extraordinary properties, including its high fracture toughness and chemical resistance, zirconia-based ceramics have long been preferred for fabrication of lab equipment and a variety of medical applications, including hip replacements, dental crowns and bridges, to name a few.

Zirconia-based Implants

Also referred to as ceramic implants, the metal-free zirconium dental implants have today become a viable alternative to standard titanium teeth restorations. People who have sensitivity allergic reactions to metallic implants, can go for zirconium dental implants that are completely metal free.

The fake dental roots are made of special ceramic (Zirconium oxide) which is highly resistant to corrosion, fracture and heat.

Benefits

As zirconia is naturally white, the crowns and bridges made of it are very clear and are extremely similar to the condition of natural teeth and tooth roots.

Unlike the metal crowns, zirconium dental implants allow the light to pass as a normal tooth.

As far as the strength of these implants goes, they are highly stable, and are strong enough to endure wear and tear of everyday use. They are capable of lasting for a lifetime.

Due to their rough surface texture, these implants have excellent biological compatibility and are very well tolerated by the gingiva.

The implants bond exceedingly well with the jaw bone and are tolerated by the gums.

Zirconium dental implants have been approved by the FDA, German and other European Governing Boards.

These are completely metal-free implants, attracting patients with allergies or those who just do not want any metal replacements for their missing teeth.

Zirconium dental implants retain less plaque and calculus, and are virtually free of adverse concerns like metal sensitivity, inflammation, metal corrosion and physical fatigue, giving you healthier gums and improved overall health.

Zirconium based implants are definitely an ideal option for people who want to replace their damaged or missing teeth with metal-free restorations. But, as with any surgical procedure, these implants too come with some risks and problems.

Radioactivity is one of the main risks associated with Zirconia dental implants. The radioactive isotopes found in zirconium can build up inside a muffle and lead to an increased chance of various oral cancers.
