Description
Technical Field
The invention belongs to the technical field of dental medical instruments, and particularly relates to a jaw flat orthosis.
Background
The remote movement of molars of adults is a difficult problem in orthodontic work. In the development history of orthodontics, for intraoral fixation function correction, a first molar band is adopted at the initial stage, and an extraoral traction method is adopted to correct retroversion of molar at the adolescence stage. The mid-term greenfield invented a fixed piston orthosis. More recently, molar thrusters have been used.
However, the external mouth resistance is complex to wear and is not easy to accept by patients. The fixed piston type appliance and the recent molar thruster often have the problems of insufficient anchorage and difficulty in pushing the molar to move far in the using process, and the appliance can not meet the requirements of correction, particularly when the anchorage tooth is missing or loosened. In order to overcome the problem of insufficient anchorage, anchorage nails are often used clinically to strengthen anchorage, but the use of the anchorage nails increases the treatment cost, has large side effects, and often causes gum swelling pain and discomfort.
