Organic dental implants

Biological dental implants are the first choice for allergy sufferers

Dental implants can perfectly replace lost teeth. They are usually a screw made of titanium that is screwed into the jawbone. This screw serves as a replacement for a tooth root on which a dental prosthesis is subsequently fixed - e.g. a crown or bridge. Normally, these implants made of high-purity titanium are very well tolerated. Nevertheless, about 10% of patients develop some kind of allergy - a so-called titanium intolerance.


With bio dental implants, there is no metallic contact with body tissue because they are coated with a layer (coating) of niobium oxide and zirconium oxide. The extremely durable ceramic layer is only approx. 2-5 μm thick and completely encapsulates the titanium area. The coating also serves as a diffusion barrier, which is why accompanying elements of the titanium such as nickel or tin cannot penetrate into the bone tissue. This achieves a great added value, as both allergic reactions and intolerance reactions are reliably prevented.

Implementation has been complex in the past. With ceramic implants, the healing process often took longer and they were more prone to fracture. With titanium implants, the contact between metal and human tissue was sometimes difficult. If patients were allergic to titanium, or more precisely to titanium oxide particles that detached from the surface of the implants and were deposited in the tissue, this led to inflammation and, in the worst case, to the loss of the dental implant.

That is why biological dental implants were developed, which are particularly suitable for people with allergic reactions. Bio-implants consist of two parts. The implant root forms the anchor and connects to the jawbone. The dental crown is attached to the implant abutment. The implant root and implant abutment are made and inserted separately.

Conventional implants made of titanium contain small amounts of tin or nickel, which can lead to titanium intolerance in patients who are prone to allergies. Biological implants reduce the risk of these side effects to almost zero. The included ceramic zirconium oxide layer prevents the fusion ("diffusion") of metal ions with the bone tissue and prevents allergic reactions.

Bio dental implants thus have a high tolerance and are particularly suitable for allergy sufferers with a tendency to hypersensitivity.

To find out whether there is an allergy to titanium implants, a so-called "lymphocyte transformation test", or "LTT" for short, can be carried out. In this test, blood is taken from the patient and examined in the laboratory. The blood analysis carried out there is used to determine whether the lymphocytes in the blood are compatible with the material titanium. The costs amount to about 150.00 euros. The test can be used to determine in advance which material is suitable as a dental prosthesis.

Biological dental implants offer a good tooth replacement for allergy sufferers or people who have a tendency to hypersensitivity. They have no metallic contact with the surrounding body tissue and are therefore well tolerated. They avoid the deposition of metallic elements in the body and protect against harmful bacteria. Organic dentures also protect against periimplantitis and other secondary diseases.

The indication areas are identical in principle to those for a normal titanium implant. The nanoscaled ceramic coating makes it possible to preserve the surface morphology of proven titanium surfaces. The coating is not only a wear-resistant but also a biocompatible titanium corrosion protection. Therefore, in the context of peri-implantitis prevention, its relevance is not only obvious but also sensible. Titanium and ceramics are joined without gaps and with high strength. That is why the use of alternative materials to pure titanium seems quite conceivable.
