Dentures: Keep information about the materials used because of allergy risk

A new denture can trigger an allergic reaction, with the risk increasing with the number of materials used, reports the Kuratorium PERFECT Dentures (KpZ) in a current press release. The patient should therefore keep the information on the dental materials used well. Over 20,000 different allergy triggers are known and "Materials that are used in dentures can be one of them," explained the head of the scientific advisory board of the KpZ, Professor Hans-Christoph Lauer.

Since a denture and therefore the materials used usually remain in the mouth for years or even decades, the experts at the KpZ recommend that the information about the denture, which is given to the patient with the so-called declaration of conformity, be kept in a safe place. “It happens that a patient has up to twenty different materials in their mouth. This increases the risk of an allergic reaction, ”emphasized Professor Jürgen Geis-Gerstorfer, member of the scientific advisory board of the KpZ. Sores and eczema may form in the mouth, accompanied by painful mouth burning.

Declaration of conformity must be handed over The experts at the KpZ report that modern dentistry and dental technology today use numerous different materials, from "adhesives, cements and impression materials to plastics and ceramics to amalgam, gold, titanium and alloys (mixtures of different metals)" pass. With the large number of materials used, not only have the treatment options improved, but the risk of an allergic reaction has also increased. Anyone suffering from a known allergy should “inform their dental practice about critical materials or medication before starting therapy,” the KpZ pointed out. The declaration of conformity can also be used to determine which materials are already in the patient's mouth. According to the KpZ, dentists are obliged to hand over the declaration of conformity to their patients at the end of treatment if they are provided with dentures.

Allergic reactions due to a metal mix in the mouth of the patient Based on the declarations of conformity, "the dentist can then follow up on subsequent dental work to understand which materials have already been used," explained Professor Geis-Gerstorfer. This is particularly important, for example, if various metallic materials have already been used and more are to be used. Because "alloys can differ electrochemically" and in the mouth there is a "metal mix" that may lead to incompatibilities, reports the KpZ. The experts recommend ceramics as a well-tolerated dental material: "All-ceramic looks deceptively similar to natural tooth enamel and is considered to be particularly bio-compatible." However, ceramics are also expensive and are usually only partially financed by the statutory health insurance companies. In any case, according to the KpZ's recommendation, patients should openly discuss materials in their dentist's office before starting therapy. (fp)
