The present invention relates to a torsional vibration resonance frequency measuring method and and a novel amplitude transformer for assessing the stability of dental implants, wherein the measuring method of torisional vibration resonance frequency for assessing the stability of dental implants comprisies installing a novel amplitude transformer, energizing a torisonal vibration mode of the amplitude transformer system, gathering resonance signals and analyzing the resonance frequencies, which is capable of detecting the stability of dental implants, continuously monitoring osseointegration in clinical treatments and directing to determine the opportunity of restoring implants, and wherein the novel amplitude transformer ccomprises an anti-rotary horizontal double-winged component and a central bolt, which is in favour of energizing torsional vibrations of the dental implants and thus detects the resonance frequency of the dental implant in torsional vibration mode, thus to increase the the sensibility of the stiffness of the bone in the bone-interface area of the dental implant, avoid the mixed influence from the non-correlation facotrs, and detect the stability of the dental implant, providing a scientific and effective method for continuous osseointegration detection and research.
