Dental implant fatigue test device

Abstract

The invention discloses a dental implant fatigue test device, which comprises a loading device and a fixing device, the loading device comprises a cross staggered universal joint structure, can realize vertical loading and small-amplitude adjustment of the position of a contact point, not only can ensure a certain horizontal activity amount, but also has enough rigidity and stability to ensure axial loading, so that the loading device is simple in structure and convenient to use. And the loading head is convenient to replace. The fixing device comprises an arc-shaped chute angle adjusting device, an angle locking device, an implant fixing cylinder and a base connecting device, and can realize the change of the integral central axis and the vertical angle of the implant, the adjustment of the rotating angle of the central axis, the positioning and clamping of the implant and the adjustment of the horizontal position of the implant. Therefore, centering of the loading device and the bearing component is guaranteed, various implants can be fixed for fatigue tests, and requirements of fatigue tests of most implants in the market can be met.

Description

technical field [0001] The invention relates to a fatigue test loading device, in particular to a dental implant fatigue test loading device. Background technique [0002] At present, implant treatment has become a common method of tooth restoration. The fatigue performance of the implant is very important, which is directly related to the service life of the implant in the human body. In this regard, the international standard ISO 14801 has been formulated internationally, which specifies the test method for dental implant fatigue tests, and my country has also formulated the industry standard YY / T 0521. Only schematic diagrams are provided for loading and securing devices in the standard, see figure 1 with figure 2 . in figure 1 is a schematic diagram of the test setup for an implant system that includes no pre-angled joints, figure 2 Schematic diagram of the test setup for the implant system with pre-angled joints. figure 1 , figure 2 1 is the loading part, 2 i...

Problems solved by technology

[0004] 2. Fixing device: Different types of implants have different angles between the central axis and the loading direction of the testing equipment, so it is difficult to complete the fatigue test of various implants with the same set of test devices

After the sample is fixed, the alignment between the loading device and the bearing part cannot be adjusted flexibly, and the error tolerance rate is low
