    (20150402 )

    1. in adolescents, expansion across the suture can be done in many ways, () ACE

    (A) rapid expansion with a jackscrew device attached to the maxillary posterior teeth, the original

    (1960s) method, typically at the rate of 0.5~1 mm/day

    (B) rapid expansion with a jackscrew device attached to the maxillary posterior teeth, the original

    (1960s) method, typically at the rate of 1~1.5 mm/day

    (C) slow expansion with the same device at the rate of approximately 1 mm per week, the method

    advocated more recently

    (D) slow expansion with the same device at the rate of approximately 2 mm per month, the method

    advocated more recently

    (E) expansion with a device attached to bone screws or implants, so that the force is directly applied to

    the bone and there is no pressure against the teeth
