Device for expanding maxillary dental arch through automatic force application

Abstract

The invention discloses a device for expanding a maxillary dental arch through automatic force application. The device comprises a support, force application rods, a driving mechanism and a guide mechanism, wherein the force application rods are slidably connected with the guide mechanism, the guide mechanism and the driving mechanism make the force application rods horizontally move towards the outer side or the inner side of the support, the guide mechanism is fixedly arranged on the support, the output end of the driving mechanism is connected with the force input ends of the force application rods, the force application rods are arranged at the two sides of the support, and the guide mechanism and the driving mechanism make the force application rods horizontally move towards the outer side or the inner side of the support; and the guide mechanism comprises a guide rail and a guide sliding block, and the sliding block is slidably arranged on the guide rail and is also connected with the output ends of the force application rods and the output end of the driving mechanism. Automatic force application of an arch expander can be achieved, and the situation is avoided that the treatment progress and effect are influenced due to poor compliance of a patient; force application parameters can be adjusted according to the condition of the patient, and the comfort of the patient in the treatment process can be improved through single small-distance and high-frequency force application; and improvement from traditional maxillary arch expansion to high implementation rate increase is achieved to ensure the clinical arch expansion effect.

Description

technical field [0001] The invention belongs to the field of orthodontic instruments, in particular to a device for automatically applying force to expand a maxillary dental arch. Background technique [0002] Dental arch stenosis, especially maxillary dental arch stenosis, is a common clinical malocclusion. The traditional treatment method is to open the palatal suture by loading a large mechanical force, so that new bone can continue to be deposited in the palatal suture, thereby enlarging the maxillary dental arch. Wide, improve malocclusion, types include Hass expander, Hyrax expander, four-eye ring spring expander, MSE, etc., which are widely used in clinic and have achieved considerable curative effect. [0003] However, the traditional arch expander has the following problems in the process of action: 1. The loading force is relatively large, which is easy to cause damage to the maxilla. For example, gravity combined with high-frequency force may cause facial deformit...

Problems solved by technology

[0004] In order to solve the problems existing in the prior art, the present invention provides a device for automatically applying force to expand the maxillary dental arch to solve the dependence on the patient's dependence on manual force in clinical practice, and by reducing the value of the loading force and increasing the The way of force frequency reduces the discomfort during the treatment process, improves the treatment effect and comfort
