Which conditions cause corrosion on metallic implants?

The most important characteristics of body fluids that influence the corrosion of metal implants are the chloride, dissolved oxygen and pH levels.

How does corrosion affect medical implants?

As a material starts to corrode, the dissolution of metal will lead to erosion which in turn will eventually lead to brittleness and fracture of the implant. Once the material fractures, corrosion gets accelerated due to increase in the amount of exposed surface area and loss of protective oxide layer.

What happens when dental implant fails?

A failed dental implant is easily removed with local anesthesia. If an implant needs to be replaced, they will take it out and gently clean the area. If the bone is intact around the area of the removed implant, no bone graft will be necessary.

Does corrosion affect human health?

Things that are corrosive can destroy (or at least damage) metal. Eventually, corrosives can cause damage to not only metal but the human digestive tract, respiratory tract, eyes, and skin. The effects of corrosion can threaten our very lives.

Where does galvanic corrosion occur?

Galvanic corrosion (also called ‘ dissimilar metal corrosion’ or wrongly ‘electrolysis’) refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte. It occurs when two (or more) dissimilar metals are brought into electrical contact under water.

Can metal rust inside your body?

The performance of any material in the human body is controlled by two sets of characteristics: biofunctionality and biocompatibility. The titanium and Co-Cr alloys do not corrode in the body; however, metal ions slowly diffuse through the oxide layer and accumulate in the tissue.

How long does it take for titanium to corrode?

Titanium has Excellent Corrosion Resistant Properties After 70 days the film grows steadily to 50 Å, slowly increasing to 80 to 90 Å after 545 days, and 250 Å in four years.

Do dental implants stop bone loss?

Today, implants with attached crowns are the preferred method for treating tooth loss because they function the same as natural teeth and help preserve the jaw structure by preventing atrophy from bone loss. Bridgework and dentures address the cosmetic problem of missing teeth but do not prevent bone loss.

Can you fix a failed bone graft?

There is a higher risk for bone graft failure in patients with existing medical conditions or are smokers. The good news is your dentist will still be able to remove and replace the failed bone graft with a second bone graft procedure, once the surgical area is healed.
