Relieves chin muscle tension.
Solve the laughing gums.
No matter how severe the gum baring is, as long as the bone nail is vertically controlled, the MIA concept is implemented from beginning to end, and the continuous light force, the amount of pressure is enough, and the time is long enough, it can be completely solved.

The lower incisor is congenitally missing in the lower jaw, so we will extract one less and make a false midline.
