Jaw frame type bionic movement mechanism fatigue test device

Abstract

The invention aims at providing a jaw frame type bionic movement mechanism fatigue test device. The jaw frame type bionic movement mechanism fatigue test device comprises a jaw frame type bionic movement mechanism, a motor, a speed reducer, a groove-cam mechanism and a base, wherein the jaw frame type bionic movement mechanism, the motor, the speed reducer and the groove-cam mechanism are arranged on the base; the speed reducer is connected with the motor and the groove-cam mechanism respectively; and the jaw frame type bionic movement mechanism is connected with the groove-cam mechanism. Thejaw frame type bionic movement mechanism fatigue test device has a simple structure, is practical, convenient to carry, intelligent to control and accurate to test, can precisely adjust the size according to various opening requirements of the activity of a multi-bending spring on the cheek side, precisely measure a fatigue period of the multi-bending spring and immediately brake when the multi-bending spring is broken, and is applied to fatigue performance test of the multi-bending spring effectively.

Description

technical field [0001] The invention relates to a test device for a bionic orthodontic mechanism. Background technique [0002] The buccal multi-flex spring movable appliance is a new type of orthodontic movable appliance for treating Angle III malocclusion in the stage of milk and replacement teeth. The mechanism of action of the appliance is mainly to use the soft elastic force of the multi-buccal spring to push the maxilla forward to promote its development, while inhibiting the excessive forward development of the mandible and making it functionally retreat to relieve underbite. It has been used clinically for many years and has achieved satisfactory results. [0003] However, some problems related to materials and mechanics were also found in the process of applying the buccal multi-curved spring movable appliance: 1. Since the performance of the stainless steel arch wire is not suitable for the shape and stress of the buccal multi-curved spring, the average 1- In 3 m...

Problems solved by technology

[0003] However, some problems related to materials and mechanics were also found in the process of applying the buccal multi-curved spring movable appliance: 1. Since the performance of the stainless steel arch wire is not suitable for the shape and stress of the buccal multi-curved spring, the average 1- In 3 months, there will be fractures in the stress concentration area of ​​the multi-curved spring, so on average, 4-7 appliances will be used in the whole process of correction for each child, and the production time of each appliance is 3-4 hours. During the period of appliance redoing, it brings unnecessary trouble to the continuity of the course of treatment, that is, every time a new appliance is replaced, the child stops wearing it for at least one week, thus prolonging the course of treatment and increasing the number of follow-up visits by the patient and parents

At the same time, it also increases the amount of labor and time costs for doctors and technicians

2. Since this appliance is a new invention, there are no relevant documents for reference on the bending, material type, and diameter of the buccal multi-curved stainless steel arch wire. Facing the many types, diameters, and bending methods of stainless steel wire, there is no A good testing instrument cannot further improve this kind of appliance to better meet the clinical needs

The existing fatigue tester cannot effectively test the multi-curved spring of the oral orthodontic appliance regardless of the direction of motion or the trajectory of motion
