If You Want Dental Implants, You Want Metal-Free Zirconia – Here’s Why

No one wants to lose a tooth, but sometimes it happens. When it does, you’ve got three options for replacing it: a bridge, a partial denture, or an implant.

Implants are the closest thing you can get to natural teeth, and this is because of how they work.

Where once there were roots, a screw-shaped object is surgically implanted into the jaw. As the site heals, the implant strongly fuses to the jawbone. A crown is then attached to the top, creating an artificial tooth that looks and functions just like a natural one.

At first, all implant screws were made of titanium, but these days, ceramic implants offer another option.

For one, titanium – like many other metals – can corrode. When it does, particles of the metal are released, causing inflammation around the implant. The resulting condition is known as peri-implantitis. The inflammation destroys both the bone and soft tissues around the implant. This provides spaces for bacteria to invade and infect the area. If this goes far enough, the implant may fail and need to be removed.

According to one study in the Journal of Clinical Periodontology, over the course of 20-plus years, roughly 22% of all implant patients developed this condition, and nearly 55% developed peri-implant mucositis, a precursor to the condition.

Other research has found that nearly one-third of patients who develop peri-implantitis said that living with the condition was “terrible.”

Another risk of titanium is that, like some other implanted metals, it may promote autoimmune dysfunction, depending on the individual’s genetics, health behaviors, and other lifestyle and environmental factors. Nonetheless,

the scientific literature is abundant with studies and cases of individuals improving or recovering from autoimmune disease usually within a year or two after removal of the offending metal….

Some of health conditions that improved (or from which patients even recovered) after removal of metal medical and dental implants and devices include a variant of amyotrophic lateral sclerosis (Lou Gehrig’s Disease) known as progressive muscular atrophy, autoimmune thyroiditis, chronic fatigue syndrome, Crohn’s disease, fibromyalgia, multiple sclerosis, oral lichen planus, Sjögren’s syndrome, and systemic lupus erythematosus.

Some individuals are even allergic to the titanium itself. Studies have shown that there’s been an overall increase in metal allergies. When the offending metal is titanium, the effects can be dramatic.

In one case, a fifty-four-year-old man with a titanium dental implant and four titanium screws in his vertebra became so sick he could not work. Chronic fatigue syndrome, cognitive impairment, Parkinson’s-like trembling, and severe depression plagued him. Six months after removing the implants and screws, he was well enough to return to work.

A fourteen-year-old girl developed inflammatory lesions on her face six months after receiving titanium orthodontic brackets. Her reactivity to titanium skyrocketed, and she became mentally and physically exhausted. Within nine months after replacing the brackets with metal-free material, her facial lesions almost completely disappeared, and she was healthy and active.

Additionally, there’s the problem of oral galvanism. If titanium implants are present in the mouth along with other metals, such as a gold crown or “silver” mercury filling, electrical currents are generated. As we noted earlier, these can interfere with health in a big way.

Such troubles – corrosion, metal allergies and toxicities, and galvanism – just aren’t an issue with ceramic implants. That’s why we feel metal-free is the way to go. Zirconia implants have other advantages, as well.

Ceramic implants retain less plaque and calculus than titanium resulting in healthier gums and overall health. The rough surface of zirconium integrates or attaches itself exceedingly well to the jawbone.

They do require some special care when it comes to hygiene – just as bridges and dentures require special care – but for both appearance and function, ceramic implants just can’t be beat.
