One study investigated 56 patients who developed severe health problems after receiving titanium-based dental implants. These medical problems included muscle, joint, and nerve pain; chronic fatigue syndrome; neurological problems; depression; and skin inflammation.
Removal of the implants resulted in a dramatic improvement in the patients’ symptoms, as well as a decrease in many patients’ sensitivity to titanium.
For example, a 54-year-old man with a titanium dental implant and four titanium screws in his vertebra was so sick that he could not work. He suffered from chronic fatigue syndrome, cognitive impairment, Parkinson-like trembling, and severe depression. Six months after the removal of the implants and screws, he was able to return to work.
In another case, a 14-year-old girl developed inflammatory lesions on her face six months after being fitted with titanium orthodontal brackets.
She was also mentally and physically exhausted, and her reactivity to titanium skyrocketed. Within nine months of replacing the brackets with a metal-free material, her facial lesions had almost completely healed, she was healthy and active, and her sensitivity to titanium returned to a normal level.
Titanium Implants Can Cause Cancer
Another complication of the use of implanted titanium is its potential to induce the abnormal proliferation of cells (neoplasia), which can lead to the development of malignant tumors and cancer. Through rare, it is a well-known complication of orthopedic surgery that involves the implantation of metallic hardware.
Furthermore, researchers recently uncovered the first reported case of a sarcoma arising in association with a dental implant.
As described in the August 2008 issue of JADA (The Journal of the American Dental Association), a 38-year-old woman developed bone cancer eleven months after receiving a titanium dental implant. Luckily, she was successfully treated with chemotherapy, but the authors recommended further research into the tumor-causing potential of dental implants in light of their increasing popularity and their ability to last for longer periods of time.
