Abstract
The present application discloses a vibration application method including a stage for contacting a contact portion with at least one tooth, and a stage for causing the contact portion to vibrate so as to impart displacement of 0.04 μm or more to the contact portion. The difference between the maximum value and minimum value of a vibrational load during the time the contact portion is vibrating may be 3 gf to 10 gf. The stage for contacting the contact portion with the at least one tooth may include a stage for contacting the contact portion with an orthodontic appliance attached to the at least one tooth.
Claims4
A vibration application method comprising steps of:
- contacting a contact portion with at least one of teeth or an orthodontic appliance that is attached for orthodontic treatment of the at least one of the teeth;
- and
- vibrating the contact portion so that the contact portion displaces by no less than 0.04 μm under a condition in which the contact portion is fixed onto the at least one of the teeth or the orthodontic appliance,
- wherein vibration of the contact portion has a wave number of no less than 3600 per day,
- wherein a difference between a maximum value and a minimum value of a vibrational load which is given the at least one of teeth or the orthodontic appliance is no less than 3 gf and no more than 6 gf during the vibration of the contact portion, and
- wherein a combination of the wave number and the difference activates metabolism of periodontal ligament and alveolar bone to shorten a period of orthodontic treatment.
