Interventions

  • DeviceLow-Intensity Pulsed Ultrasound

    The total sample will be randomly divided into two equal groups (according to method of application of the lipus on the intervention side)as follows: ■ Group I: will include 8 patients who will receive lipus with maxillary canine retraction that will be performed every (3 weeks) on intervention 6 sides according to a standardized protocol. ▪ Group II: will include 8 patients who will receive lipus that will be performed every (1 week) on intervention sides according to a standardized protocol.
