Ceramic materials can sometimes have adverse effects on the organism as well. Ceramics are comprised of up to 80 percent aluminum oxide, an essential component of ceramic dental materials. Studies have shown that aluminum can be been detected in the brain as a result. In combination with mercury, aluminum is associated with Alzheimer's disease.
Adhesives and joining materials in compressed ceramics have allergic and toxic properties. Feldspar ceramics are also radioactive.
The Lymphocyte Transformation Test (LTT) or the more specific ITT Immunotolerance test can be used to show the individual patient's immune specific response in the blood to the ceramic materials used.
Zirconiumdioxyde or also with the trivial name Zircon oxide, is the most frequent connection in the nature after the pure zirconium itself. Zirconiumdioxid ZrO2 is high-capacity ceramics, a non-metallic, inorganic material, and belongs to the group of the oxide ceramics.From us commissioned investigations to detect the radioactivity have shown that the zirconium ® used by us has no raised radioactivity compared to the normal radioactivity of the environment. Also the white sandy beaches of Sri Lanka where we can find Zirkoniumdioxide would be closed if a raised radioactivity is detected.Because of his white colour Zirconiumdioxid is preferred to the metal alloys in aesthetic to areas like the front teeth area and the gingival margin.In contrast to metals and metal alloys it undergoes no corrosion in the oral cavity not even if the patient takes sour dishes. Also it hardly leads the warmth and the supplied teeth are less sensitive to warmth.The elasticity module it is almost like feather-hard steel (which is used for clip prosthesis) and we can do long bridge reconstructions with up to 4 teeth to be substituted. On the smooth ceramic surface bacteria don`t attach and grow as they do on the surface of metal alloys or titanium
