A multi-posture dental implant test device for simulating occlusal teeth

Abstract

The invention relates to a multi-posture dental implant testing device for simulating tooth occlusion, belonging to the field of stomatology equipment, and relates to a multi-posture dental implant testing device for simulating tooth occlusal. The test device consists of an L-shaped machine table, upper and lower jaw modules, four three-way force sensors, five linear drives, columns, joint bearings and small shafts. One end of the fourth and fifth linear actuators in the device is hinged on the bottom plane of the L-shaped machine, and the other end is hinged on the bottom surface of the lower jaw module; the column is fixed on the bottom plane of the L-shaped machine, and the column and the lower jaw module are connected by joint bearings. The joint bearing is connected to the rear side of the jaw module via a small shaft. One end of the first, second and third linear actuators is hinged on the side of the L-shaped machine table, and the other end is respectively hinged on the top surface of the upper jaw module and the rear end side of the upper jaw module. The test device can test and evaluate the performance of the implant under the action of multi-position occlusal forces, and has the characteristics of simulating multi-position occlusal modes and high test efficiency.

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.
