[Intrinsic chemical stability of resins for removable dentures]
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.

Relative Reactivity of Carboxylic Acid Derivatives
A key factor in assessing the reactivity of the acid derivatives is the basicity of the substituent or the leaving group. The lower the basicity of the leaving group, the higher the reactivity of the derivative. The basicity of the leaving group follows this order:
Halide ions < Acyloxy ions < Alkoxy ions < Amine ions
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
