Abstract
Monitoring dynamical occlusal tooth contacts have a lot of significance and potentialities for clinical application.
The purpose of this project was to establish the method for monitoring dynamical occlusal contacts by tooth vibration with miniature accelerometers attached on tooth surface.
In this study, the evaluation on the accelerometer fixation method on tooth surface were conducted. A miniature accelerometer (MA 3: Morita, Co.) were examined on the vibration table with several kinds of fixation method and received the vibration caused by the random noise. The coherence, gain and phase of each obtained data were analyzed on Fast Fourier Transform (FFT) and compared.
As the result, the most suitable fixation method of the accelerometer determined by the manipulation in clinical situations and in above mentioned factors was the one in which the resin core with and accelerometer bonded by cyanoacrylate bonding agent was fixed on the tooth surface by two-sided adhesive tape.
