Since the establishment of modern implant systems, the stability of dental implants has been a very important factor in the success of dental implants. Is an important guarantee for smoothly finishing osseointegration. Clinicians often rely on experience or literature references to assess whether dental implants are sufficiently stable to allow superstructure restoration, whether based on occlusal forces or X-ray films, which are subjective factors and cannot be continuously tracked and measured. Since it is necessary to determine that the fabrication of the implant superstructure can be started after the bone healing and the good osseointegration of the implant have been achieved, a safe time point with subjective judgment may necessitate a relatively long waiting time for the patient, and the patient may receive the implant superstructure repair too early, resulting in incomplete osseointegration of the implant or damaged osseointegration. Therefore, before the second stage of repair, an appropriate method for measuring the stability of the implant at this time is required to determine whether the osseointegration of the implant is completed.
