Metal Free Dental Implants/ Ceramic Implants/ Zirconia Implants
These are 10 reasons why you should consider Metal Free Dental Implants such as Ceramic Implants and Zirconia Implants
1. Biocompatibilty and optimal Osseointegration
Zirconia Implants are biocompatible and ceramic which allows complete assimilation into jaw bone. According to a study performed at University of Minnesota, it was confirmed that there was additionally no signs of inflammation or foreign body rejection.
2. Allergies and Sensitivities
Zirconia Implants are hypoallergenic. Titanium Implant sensitivity shows up years after surgery and typically itchiness and inflammation can develop around implant sites.
For especially those who have allergies, skin sensitivities and compromised immune systems, a metal free dental implant might be a better solution.
With those who have thin or translucent gums, titanium implants can show up as having a grey gumline or margin. Zirconia is non metallic and white, hence it is much more natural looking that titanium. It is a perfect base colour which mimics natural teeth comparatively to titanium implants.
4. Corrosion Resistant
Zirconia is resistant to chemical corrosion and does not conduct electricity or heat. Because it is bio inert, it will never trigger chemical reactions, migrate to other sites in the body or interfere with the maintenance of optimal oral health. Titanium however can corrode in the wet environment of the mouth and especially if there is more than one metal in the area such as amalgam fillings, alloy metal crowns, bridges or gold inlays. Metal corrosion is even more active in the presence of fluoride that is free flowing in water supplies, toothpastes or mouthwashes. Scientific articles have cited that titanium can also migrate from the implant site into surrounding tissues and even into nearby lymph nodes.
5. Non conductivity of zirconia
Because zirconia does not conduct an electrical charge reduces the collection of bacterial growth. This hence creates an oral environment and gums which are healthier.
6. Holistic friendly
Zirconia and metal free implant do not interfere with the movement of energy through the body’s meridian. Hence if you adhere to holistic health principles, this is the perfect tooth replacement for you.
Zirconia as a material, is well known for its durability and inflexibility under pressure. Hence it is particularly well suited to withstand tremendous masticatory or biting forces.
8. One piece design
One of the problems with titanium implants, is the joint between the implant in the jaw and the abutment (post) that sits above the gumline. Because this is a joint, there is always a chance of micro movement and microleakage. This is due to the extreme pressures of chewing. Hence bacteria has an opportunity to colonise this area leading to smell, bone loss and implant failure in the area. Many zirconia implants are hence one piece design to avoid this problem. ZERAMEX is an example of a metal free dental implant brand which is however two piece and has been shown to have great success rates.
9. One stage surgery
Many zirconia implants are designed for the immediate placement after tooth extraction. This one stage surgical approach minimised implantation time and maximised comfort. Also there is usually less invasive surgery i.e.: without incisions or sutures (Only possible when there is no infection and that there is sufficient bone in the implant site)
