The principle of low friction correction and the development of its appliance

​Nowadays, many scholars in orthodontic circles advocate the concept of light force correction. In order to achieve the effectiveness of light force correction, the first thing is to reduce the friction of the correction system. Since the late 1990s, some new fixed appliances have been introduced in the world. One of the directions of improvement or renewal is to reduce the friction of bracket groove, so as to realize light force correction.

Develop a brief history of invisible correction knowledge

​Oral and maxillofacial system is a complex composed of mountain teeth, periodontal supporting tissue, jaw, yimandibular joint, oral and maxillofacial nerves, muscles and other related tissues, which coordinate and restrict each other. The oral and maxillofacial system continues to undergo various forms of adaptive reconstruction in people's life. This change is particularly obvious in the peak period of human growth and development. The poor function of lip, tongue, maxillofacial muscles and other tissues is also one of the important factors in the etiology and development of many malocclusion deformities.
