Description
Technical Field
The invention relates to the technical field of oral treatment, in particular to a novel orthodontic force measuring method and device.
Background
Orthodontics (Orthodontics) are the correction of teeth and the relief of malocclusions. Orthodontics mainly researches the etiology and mechanism of malocclusion deformity, diagnoses, analyzes, prevents and treats the malocclusion deformity, and can achieve the effect of beautifying teeth. The english name of orthodontics is derived from a combination of three greek roots, which are meant as "teeth", "correction" and "discipline", known as "corrected teeth". Orthodontic treatment is mainly to adjust the coordination among nerves and muscles of facial bones, teeth and maxillofacial parts, that is, to adjust abnormal relationships among maxilla and mandible, between upper and lower teeth, between teeth and jawbone, and between nerves and muscles connecting them, by various orthodontic devices, with the ultimate aim of correction being to achieve balance, stability and beauty of the oromandibular system. The correction of the malocclusion (occlusal deformity) mainly depends on wearing a correction device inside or outside the oral cavity to apply proper 'biological materials' to teeth, alveolar bones and jawbone so as to cause the teeth, the alveolar bones and the jawbone to generate physiological movement, thereby correcting the malocclusion (occlusal deformity).
At present, the tooth moving direction, the correcting force and the moment are mainly judged by the experience of a doctor, and the orthodontic doctor replaces the arch wire in a proper period according to the experience to help a patient to achieve the expected correcting effect.
Therefore, the method for accurately measuring the orthodontic force on the teeth in the orthodontic process has great significance for popularizing the orthodontic technology in a wider range.
