Titanium
Titanium has established itself in recent decades as a standard material for dental implants. Typically, pure titanium is used. As distinct from metal alloys, corrosion plays a subordinate role to abrasion with pure titanium. This abrasion is a frequent cause for individual intolerance of titanium.
It is known that such abrasion particles are absorbed into the tissue surrounding the implant and can cause a strong infection with the corresponding disposition.
The particles can be detected in the lymph nodes and blood following implantation. These titanium intolerances are often falsely diagnosed as type IV allergies.
Aluminium and vanadium are also toxic components of titanium alloys which can also be of significance for allergic intolerances.
