Abstract:
An orthodontic device generating cyclic tensility is provided to reduce time for orthodontic treatment by periodic generation and release of tensility. An orthodontic device generating cyclic tensility includes: an operation body established between a traction body and a fixation body combined with teeth to be treated, which allows generation and release of traction power by elasticity on the traction body and includes a housing(32) equipped with a combining implement to be fixed with either the traction body or the fixation body, and an actuator(35) to make a load move; and a control unit(40) to control for the operation body to generate and release traction power on the traction body in a prescribed driving cycle.
