Multi-posture implanted tooth testing device capable of simulating tooth occlusion

Abstract

The invention relates to a multi-posture implanted tooth testing device capable of simulating tooth occlusion and belongs to the field of oral medical equipment. The testing device is composed of an L-shaped machine platform, an upper jaw module, a lower jaw module, four three-directional force sensors, five linear drivers, a stand column, a joint bearing and a small shaft. In the device, one end of the fourth linear driver and one end of the fifth linear driver are hinged to a bottom plane of the L-shaped machine platform, and the other ends of the fourth linear driver and the fifth linear driver are hinged to a bottom surface of the lower jaw module; the stand column is fixed on the bottom plane of the L-shaped machine platform; the stand column is connected with the lower jaw module through the joint bearing; the joint bearing is connected to the rear side face of the lower jaw module through the small shaft. One end of the first linear driver, one end of the second linear driver and one end of the third linear driver are hinged to the side face of the L-shaped machine platform, and the other ends of the first linear driver, the second linear driver and the third linear driver are hinged to the top surface of the upper jaw module and the rear end side face of the upper jaw module respectively. The testing device can be used for testing and evaluating properties of an implanted tooth under the action of a multi-posture tooth occlusion force, and has the characteristics that a multi-posture occlusion manner is simulated, the testing efficiency is high and the like.

Description

technical field [0001] The invention belongs to the field of stomatology equipment, and relates to a multi-posture dental implant test device for simulating tooth occlusal. Background technique [0002] Dental implant refers to a way to restore missing teeth based on the lower structure implanted in bone tissue to support and retain the upper tooth restoration. It is the most remarkable technological development in the history of stomatology in the 20th century. It changes the support and retention mode of traditional denture restoration, and realizes the biological and mechanical combination of artificial teeth and jawbone. A typical dental implant structure includes two parts: the lower supporting implant and the upper dental restoration. The implant consists of a body, a neck, and an abutment. During the long-term service after implantation, the implant will bear various complex loads in the oral environment, such as different occlusal force, occlusal area, occlusal posi...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to invent a test device that simulates the multi-position occlusion of the real oral cavity, so as to solve the problem that the current test of the implant performance is different from the stress environment of the implant.
