Does the Harley-Davidson retainer need regular afterloading?

Harley-Davidson retainer does not need to be installed regularly. Harley-Davidson retainer can fine-tune teeth. Harley retainer can automatically apply force according to the width of the patient's teeth, and at the same time, it can directly apply force to the retainer through the adjustment of the doctor to achieve the effect of shrinking teeth. Harley-Davidson retainer needs to be worn for 24 hours for a long time, and the teeth are contracted by the strength of the retainer. The retainer should be worn according to the doctor's instructions. Do not wear it at will, and do not apply force to the retainer by yourself.
