Adaptation of currently used resins in prosthodontics

: This study is intended to detail the relative level of adaptation (at the hiatus palatinus) of five (5) acrylic resins used in partial and complete prosthodontics (Formatray, Orthodontic, Triad, Lucitone, Ivocap). These five (5) resins have been treated to five (5) different methods of conservation (in water at different temperatures, to air and to cold) to discover which of these methods are most likely to conserve the accuracy of adaptation one looks for in a resin.
