Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a stability measuring instrument for dental implants. Background Art

[0002] The stability of dental implants is a very important factor in the success of dental implants. According to the literature, it can be determined that the success rate of dental implant treatment is higher in areas with better bone density. Class IV alveolar bones have the lowest bone density and a higher implant failure rate than other types of alveolar bones.

[0003] When evaluating whether the stability of dental implants is suitable for superstructure repair, clinicians often rely on experience or reference reports. Whether it is based on occlusal force or X-rays, it contains subjective judgment factors and cannot be continuously tracked and measured. Since the implant superstructure can only be made after bone healing and implant bone integration are confirmed, the safe time point with subjective judgment may cause patients to spend more waiting time, and may also cause patients to accept implant superstructure repair too early, resulting in incomplete implant bone integration or bone integration being destroyed. Therefore, before the second stage of repair, an appropriate method is urgently needed to measure the stability of the implant at this time to determine whether the implant bone integration is complete.

[0004] The current new generation of non-invasive dental implant stability detection devices is based on the overall resonance frequency (resonance frequency) of the retention state between the implant and the alveolar bone. It uses the change in resonance frequency caused by the change in the bone boundary during the healing process of the implant as a reference for judging the fit between the dental implant and the surrounding bone. This analysis method is also called implant resonance frequency analysis (RFA), which is a non-invasive and non-destructive vibration detection method. However, the related equipment is large in size, has poor stability, is not easy to operate, and is not very portable. Utility Model Content
