This study was undertaken with the intent of seeking the structural stability in connection parts of various formes of experimental one-piece cast bridge prosthetics, It is well known that connection parts of bridge is infuluenced by the factor of stress concentration. The mastication force was occasionally considerd as a collision force, so the impact forces were served as a model force of the vibration in this study. Impulse responses from the bridge using RION PV-90 B pick up was analysed in terms of frequency domain. In this experiment, it is important that in stead of static addition of force, dynamic vibration was employed. The results were as follows ; Peak frequency on 4 modal sections was appeared by free supporting method. Impulse response was influenced by the connection parts of variousforms in freqtuency domains.
