Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical auxiliary devices, and particularly relates to a impacted tooth tractor. BACKGROUND

[0002] The impacted tooth tractor is a medical device for correcting the position of an impacted tooth (i.e., a tooth that cannot normally erupt). Impacted teeth are often caused by insufficient tooth growth space, crowded dentition, abnormal bone development, etc. Common impacted teeth include maxillary third molars, canine teeth, and anterior teeth, etc. If not treated in time, it may cause pain, infection, and misaligned dentition, etc. Early tractors are mainly made of metal, and simple springs or wires are used to apply traction. With technological progress, modern tractors are designed more complexly, and adjustable spiral tractors and invisible tractors appear. These new devices not only improve the treatment effect, but also enhance the comfort and aesthetics of patients.

[0003] The future development of the impacted tooth tractor will move towards intelligentization and minimally invasive. Intelligent devices can monitor the changes in traction force in real time and automatically adjust according to feedback. In addition, the application of bioactive materials will promote the physiological eruption of impacted teeth, reducing treatment time and pain.
