Purported symptoms of metallosis generally include pain around the site of the implant, pseudotumors (a mass of inflamed cells that resembles a tumor but is actually collected fluids), and a noticeable rash that indicates necrosis. [1] The damaged and inflamed tissue can also contribute to loosening the implant or medical device.
Implants and prosthetics, including dental repairs, are also an exposure; dental work is the main way in which the general population is sensitized to palladium, and dental workers may get occupational palladium allergies, though cross-sensitization may also be a common way in which people develop an allergy to this fairly rare metal.
Many metals, particularly heavy metals are toxic, but some are essential, and some, such as bismuth, have a low toxicity. Metals in an oxidation state abnormal to the body may also become toxic: chromium(III) is an essential trace element, but chromium(VI) is a carcinogen. Only soluble metal-containing compounds are toxic. Soluble metals are ...
Metals can be toxic in high quantities. Either ingestion or faulty metabolic pathways can lead to metal toxicity (metal poisoning). Sources of toxic metals include cadmium from tobacco, arsenic from agriculture and mercury from volcanoes and forest fires. Nature, in the form of trees and plants, is able to trap many toxins and can bring ...
Failure of a dental implant is often related to the failure of the implant to osseointegrate correctly with the bone, or vice versa. [4] A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after.

Mercury poisoning is when a person is exposed to too much mercury, an elemental metal found in the environment or food. Over the weekend, Hall told her nearly 2 million followers she's been "super ...
Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12 . A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia .
