Abstract

Biocompatibility means that the materials of which fixed dental prostheses and implants are made of, should not irritate the surrounding structures, must not lead to the appearance of a inflammatory response or to a allergic reaction of the organism and may not release toxic ions. In the first part of the study we experimentally submitted a titanium implant abutment and three types of dental alloys (two NiCr alloys and one CoCr alloy) to a corrosion process, in similar conditions to the ones in the oral cavity (temperature: 37 ± 0,5°C ; pH values: 5.2 and 7), simulating the situation in which there is one single alloy in the oral cavity at a time. Then, we analysed the corrosion for galvanic couples made of titanium abutment - CoCr alloy and titanium abutment - NiCr alloy. According to the conducted tests, regardless of the pH value to which they have been realised, the NiCr alloys showed a better resistance to corrosion in the absence of the titanium alloy, while the CoCr alloy behaved better to corrosion in the presence of the titanium alloy.
