Summary of research:
Class II malocclusions represent approximately 30% of the reported malocclusions (bite arrangement problems) among the Canadian population. Treatment of Class II malocclusions is a common challenge for orthodontists. Fixed Class II Correctors (FFC) (orthodontic devices that are secured inside the mouth to favor the correction of this malocclusion type) have been shown to be relatively effective in Class II malocclusion correction. Although there is a significant body of data published in this area; the specific data reported about the effects of FCCs on some oral tissues remains unclear. Cone Beam computerized tomography or CBCT is an X-ray based imaging technique used to assess the gum and bone tissues and currently renders the only method to visualize and analyze the bony defects. Despite its accuracy and 3D revelation of the oral structures, the use of CBCT should always be considered by assessing its benefit versus the radiation risk to the patient. Ultrasound imaging is a non-invasive and non-destructive imaging technique used in many fields, especially medicine and engineering. The primary purpose of this randomized clinical trial is to assess the impact of Class II malocclusion correction using FCCs on periodontal tissues including gingiva and alveolar bone using a medical ultrasonic device to image and monitor teeth and gums and to compare changes with X-ray imaging.
