| Abstract | This article begins by recalling the notions of biocompatibility and bio-material, in order to define the general context of the research on the intrinsic chemical inertia of resins used for removable prostheses. The materials (10 resins), equipment and operating conditions set up to obtain the extraction liquids which are analysed according to three procedures are then treated: molecular absorption spectrophotometry under ultra-violet rays, gas phase chromatography, coupled with mass spectrometry and atomic absorption spectrometry. Gas phase chromatography coupled with mass spectrometry showed that only one resin released diethyl phthalate after an immersion duration of 8 weeks. Various propositions are discussed in order to try to explain these various behaviours. In conclusion, it appears at the end of this investigation that the resins tested (except for one) show good intrinsic chemical stability when they are used according to precise and rigorous procedures. |
