Description

Technical Field

[0001] This utility model relates to a device for measuring implant stability. Background Technology

[0002] Currently, more and more people are experiencing tooth loss or dental diseases, often requiring the implantation of dental implants into the alveolar bone, followed by an abutment and prosthesis to restore teeth. However, over time, implants may become loose, necessitating a proper assessment of their looseness. The primary testing method involves screwing a sensor into the internal threads of the implant, which is fixed to the alveolar bone. An external detector then emits a scanning frequency. When the frequency matches the inherent frequency of the implant and the sensor, the detector receives the strongest feedback signal. The strength of this signal is used to determine the implant's stability.

[0003] However, since different patients require different implant sizes, and the structural dimensions of devices used to test implant stability are usually fixed, they cannot be used to test implants of various sizes. For example, CN119405439A discloses a device for measuring the stability of alveolar bone implants, including a connecting part, a supporting part, and a magnetic part. The connecting part is configured to fix the device to the implant; one end of the supporting part is connected to the connecting part, and the other end of the supporting part is connected to the magnetic part; the magnetic part includes a cylindrical magnetic component and a shell; the shell includes a bottom surface and a side wall, the lower end of the side wall is connected to the outer periphery of the bottom surface, and the side wall and the bottom surface form a cavity; the magnetic component is disposed in the cavity formed by the bottom surface and the side wall; a groove is formed at the upper end of the side wall, and the groove is oriented along the length of the side wall.

[0039] The threaded segment includes a threaded segment body. The threaded segment body has a bottom surface and a top surface. The threaded segment body can be cylindrical. The outer circumference of the threaded segment body is provided with threaded segments. The threaded segments can be used to fix with threads provided in the implant's groove, or to fix with threads provided in the movable sleeve's internal movable sleeve.

[0040] The rod-shaped segment includes a rod-shaped segment body and a rod-shaped segment head. One end of the rod-shaped segment body is connected to the bottom surface of the threaded segment body. The other end of the rod-shaped segment body is connected to the rod-shaped segment head. The outer surface of the rod-shaped segment is smooth. The outer surface of the rod-shaped segment is not threaded. This facilitates the assembly of the movable sleeve with it.

[0041] The projection of the rod-shaped segment onto the bottom surface of the threaded segment falls within the area of ​​the bottom surface of the threaded segment. "Falls within" means not exceeding the area of ​​the bottom surface of the threaded segment; it may coincide with the bottom surface of the threaded segment or lie within it. At least 50% of the edges of the projection of the rod-shaped segment do not coincide with the edges of the bottom surface of the threaded segment; preferably, at least 60%; more preferably, at least 70%. In some embodiments, the edges of the projection of the rod-shaped segment do not coincide with the edges of the bottom surface of the threaded segment. This helps improve the stability of the movable sleeve after assembly.

[0042] In some embodiments, the projection of the rod-shaped segment body is circular. The projection of the rod-shaped segment body does not coincide with the edge of the bottom surface of the threaded segment body. Preferably, they are concentric circles. The rod-shaped segment body is a cylinder. The rod-shaped segment head extends from the rod-shaped segment body. The surface of the rod-shaped segment body is a convex, smooth arc surface.
