Description

Orthodontic accelerator

Technical Field

Background

With the progress of society and the continuous development of economy, people are gradually shifting their eyes from meeting the living needs to improving the quality of life, and oral health is also receiving more and more attention as a problem closely related to people's life. Nowadays, oral malocclusion deformity not only affects the beauty of the face, but also brings certain obstacles to employment, chance selection and the like, most people want to have healthy and tidy teeth, and thus the needs for seeing a doctor for oral problems are increasing.

In the traditional orthodontic method, the treatment period is very long, most patients need two years or even longer treatment period for orthodontic treatment, the moving speed of teeth is about one millimeter per month generally, the long treatment period is high in cost, and side effects such as tooth root absorption, tooth fixing loss and the like can be brought, so that the patients cannot accept the orthodontic treatment.

The movement of the tooth is related to the alveolar bone and periodontal ligament. The periodontal ligament is located between the tooth and the alveolar bone and is the most actively reconstructed and metabolized part, and is composed of three parts, synthetic cells, absorptive cells and interstitial cells, wherein osteoblasts (belonging to the synthetic cells) and osteoclasts (belonging to the absorptive cells) are two cells which play important roles in alveolar bone reconstruction and tooth movement. When the orthodontic force is applied to the teeth, one side of the periodontal ligament is pulled (alveolar bone tension side), osteoblasts on the side can proliferate to promote the regeneration of bone tissues; the other side of the periodontal ligament is compressed (alveolar bone pressure side), and a large amount of osteoclasts are accumulated, so that the alveolar bone is resorbed. Therefore, the speed of alveolar bone remodeling determines the moving speed of teeth during orthodontic treatment, and many studies have shown that periodontal ligament cells are activated more and metabolism is more vigorous during the application of vibration load to teeth, thereby increasing the moving speed of teeth.

The proliferative and absorptive properties of periodontal ligaments are the biological basis of orthodontic treatment, which can be accelerated by applying a vibratory load to the teeth.

The traditional orthodontic accelerator needs to be held by a tongue plate to be fixed at the oral position when in use. The connection mode between the tongue plate and the vibration main body is complex, the reliability is poor, the vibration of the connection part can be attenuated, and the defect that the vibration is unstable exists.
