Self-ligating brackets vs Conventional brackets

Amount of crowding (lower incisor crowding) at 10 weeks · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth

It is very uncertain whether self-ligating brackets changes amount of crowding (lower incisor crowding) at 10 weeks compared with conventional brackets (very low certainty).

1 finding from 1 review
  • Nam 2020: Damon 41/41 vs Hyrax 41/41; NS (no difference in crossbite correction; greater transverse molar/premolar expansion with Hyrax)
