评论

  • G6 is good for first premolar extraction cases because it works well on upper molar anchorage control and upper incisor torque control.
  • G5 attachment is good for Spee curve leveling and anterior overbite control on first premolar extraction cases.
  • For moderate anchorage cases, I narrow the arch width but don't design molar mesialization on Clincheck.
