Description
Summary:A low cost instrumentation system was proposed in this paper to determine the stability of dental implants using Resonance Frequency Analysis (RFA) technique. In the present work, an improved system has been described which provides a microcontroller based tracking of the change in resonance frequency (RF) when the dental implant is dipped in a hardening dental plaster mixture. In order to do so, the acquisition of the sensor output using the microcontroller as well as its corresponding display on the LCD has been calibrated and characterized. Thereafter, the performance of the system in tracking the change in RF in in-vitro experiments has been validated.
