Orthodontic force measuring device based on flexible six-dimensional force sensor

Abstract

The invention discloses an orthodontic force measuring device based on a flexible six-dimensional force sensor. Comprising a flexible six-dimensional force sensor, a bracket and a Bluetooth module, the flexible six-dimensional force sensor is pasted on the surface of each tooth through a biomedical adhesive, the bracket is installed at the top of the flexible six-dimensional force sensor, and the Bluetooth module connected with the flexible six-dimensional force sensor is installed on the surface of the bracket. The brackets between the adjacent teeth are connected through the orthodontic arch wires penetrating through the brackets; the orthodontic arch wire applies orthodontic force to teeth through the flexible six-dimensional force sensor, and the piezoresistive sensing unit on the flexible six-dimensional force sensor outputs a voltage signal through the Bluetooth module. According to the invention, not only can real-time detection of external stimulation in the spatial six-dimensional direction be completed, but also simultaneous acquisition of real-time data of a plurality of teeth can be realized, and a correction doctor is helped to know the suitability of orthodontic force and the tightness of a tooth hoop so as to formulate a more reasonable correction scheme.

Description

technical field [0001] The invention belongs to the technical field of orthodontic force measurement in the process of oral orthodontics, and in particular relates to an orthodontic force measurement device for orthodontics based on a flexible six-dimensional force sensor, which can assist orthodontists to formulate a reasonable correction plan. Background technique [0002] In the process of orthodontics, the orthodontic force comes from the external deformation of the orthodontic device, and the orthodontic force applied to the teeth determines the effect of orthodontic treatment. If the orthodontic force is too large, it may cause the root of the tooth to absorb , there are side effects such as pulp inflammation, tooth pain and loosening; if the orthodontic force is too small, the orthodontic effect will be greatly reduced, prolonging the treatment cycle. Therefore, appropriate orthodontic force is crucial to orthodontic treatment, and applying an orthodontic force of app...

Problems solved by technology

[0003] Most of the traditional orthodontic force measuring devices for orthodontics are equipped on the treatment table for positioning and installation. Correction is performed by fixing the brackets and bending deformation of the arch wires passing through the brackets. However, due to the fact that the arch wires cannot be accurately Positioning, the treatment effect cannot be guaranteed during the orthodontic process. This kind of measuring equipment installed in the clinic is not only inconvenient to adjust, but also the accuracy cannot be achieved very high. There are also imperfections in the face of different groups of people and different dental problems. place
