Metal Free Dental Implants

Dental implants, known as the most reliable and highly durable form of teeth restoration for missing teeth, provide the most advanced solution for tooth loss. Dental implant treatments are permanent and look just like real teeth. They also prevent jawbone and muscle deterioration, which is normal with dentures and bridges. Implants are not just for cosmetic enhancement, but also work like natural teeth, thus improving the quality of life. The confidence patients get with implants enables them to smile, talk and enjoy eating all kinds of healthy foods again. Implantation provides a simple, predicable solution with superior and positive results.

When you hear the words, “dental implants,’’ an image of a metal screw automatically comes to your mind, but did you know that there are various types of dental implants? Implant teeth consist of a range of materials, such as titanium, stainless steel, titanium alloy and zirconium oxide ceramics. Titanium dental implants are the most common and widely used form of dental implants. However, it is no longer obligatory to implant titanium or any other metal in order to have fixed teeth. Various ceramic materials exist that dental professionals use to create metal free dental implants. Metal free ceramic implants are harder than titanium dental implants. In fact, they are next to diamonds, in terms of hardness. Ceramics possess tensile strength and are similar in composition to natural teeth, thus supporting biological dentistry.

Zirconium oxide ceramics are used in the manufacture of materials that work in aggressive environments such as extrusion dyes, valves and port liners for combustion engines. Zirconium oxide implants have outstanding mechanical properties, optimal stability, a high biocompatibility and a strong resistance to scratching and corrosion. The oxide is ivory in colour, making it similar to the color of a natural tooth, which is important for restoring teeth, especially front teeth. Furthermore, its ability to transmit light makes it a suitable material in fillings that require aesthetics.

It is important to add that metal free dental implants are biocompatible, because they are fully tissue-friendly. There are no allergic reactions, no sensitivity to temperature and no impact on taste. The zirconium oxide ceramic shows no interactions with other dental materials and is electrically neutral.

As compared to titanium dental implants, metal free dental implants look more like natural teeth. Ceramic dental root implants are the preferred choice for patients who dislike the notion of having metal in their mouths, or are prone to titanium allergies.

Worthing Dental Centre offers consultancy services to patients so they can make an informed decision on the type of implants best for them. They take the time to review the advantages and disadvantages of all forms of dental implants. It is important to note that metal free implants are more expensive compared to other forms of dental implants, because of the special features they provide. However, they offer patients the most reliable, natural and permanent solution for missing teeth available today.
