简要总结
It is a randomized controlled clinical trial in which orthodontic patients undergoing upper first premolar extraction are divided into 3 groups based on frequency of vibratory force (n=18) -
Group 1 - 90 Hz (n=6)
Group 2 - 110 Hz (n=6)
Group 3 - 130 Hz (n=6) All 3 frequencies are tested in Horizontal (n=3 in each group) and Vertical (n=3 in each group) growth pattern patients to check whether the acceleration of tooth movement varies with the facial growth pattern of an individual. To check the rate of tooth movement, intra oral scans of the patients are taken at the start of retraction (T0) and after 3 months of completing retraction (T3) Pain / discomfort scores are also assessed using VAS scale.
