Objectives: Monitoring implant stability is an important factor in determining the long‐term success rate of implants. Periotest values and resonance frequency analysis have been widely used for this purpose, but these indicators mainly reflect the mobility and/or stability of implants. Thus, a no‐contact electromagnetic vibration device was developed and tested for monitoring both tooth mobility and periodontal tissue conditions. The aim of this study was to evaluate the ability of a no‐contact electromagnetic vibration device to measure implant stability under various peri‐implant conditions using mechanical parameters. Material and methods: The device consisted of three components: the vibrator, detector, and analyzer. The mechanical parameters resonant frequency, elastic modulus, and coefficient of viscosity were used to measure simulated atrophic bone defects in periodontal tissues. Results: The resonant frequency and the elastic modulus increased with an increase in supporting bone height. In contrast, the coefficient of viscosity decreased with bone height. Values for the three parameters for the formed urethane models were lower than those for the urethane models. Conclusions: A no‐contact electromagnetic vibration device may be capable of monitoring implant stability, and mechanical parameters may be useful for assessing the condition of periodontal tissues around implants.
