Comprehensive test experiment platform for orthodontic parodontium mechanical property

Abstract

The invention discloses a comprehensive test experiment platform for an orthodontic parodontium mechanical property, which comprises a base plate, a support, a clamping module and a measuring module; the support and the clamping module are arranged on the base plate; the measuring module is arranged on the upper end of the support; the base plate is provided with a longitudinal guide rail and a horizontal guide rail vertical to the longitudinal guide rail; the support and the measuring module are respectively connected with the longitudinal module in a sliding mode; and the clamping module is connected with the horizontal guide rail in a sliding mode. The clamping module of the test experiment platform provided by the invention can regulate the position in a sliding mode; and the uniaxial drawing / compression and the shearing test of a parodontium test sample can be carried out through regulating the fixture type and the relative position of the clamping module and the measuring module, and the parodontium mechanical performance can be tested under the condition of simulating tooth reshaping. The test accuracy of the device provided by the invention is relative high, and the test accuracy requirement can be met; and the device has less components, is simple in structure, is low in processing cost, and is simple to operate.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing in oral orthodontics, and in particular relates to an in vitro comprehensive test bench for mechanical properties of periodontal ligament in orthodontic tooth movement. Background technique [0002] Orthodontics refers to the direct or indirect action of orthodontic force on teeth and their supporting tissues, thereby causing a series of tissue biochemical reactions to achieve the purpose of tooth movement. In this process, orthodontic force is the external force of tooth movement. In terms of inducement, periodontal ligament biomechanical response is the determinant of tooth movement and tooth movement velocity. The biomechanical properties of the periodontal ligament are key to a correct understanding of orthodontic tooth movement, tissue response, and planning of orthodontic treatment. The current research on the biomechanical properties of periodontal tissue is mainly a combination...

AI Technical Summary

Problems solved by technology

Due to the complexity and smallness of the periodontal ligament structure, the traditional large-scale metal material testing machine cannot be effective for the smaller structure of the periodontal ligament, so that the mechanical properties of the periodontal ligament are less tested, and the test items are relatively single. The structure of the test device is complex

The lack of experimental data on the mechanical properties of the periodontal ligament has an adverse effect on the study of the mechanical model of the periodontal ligament
